Happy Birthday Dad

Finally figured out something good to do with those darn watertribe paddles. A birthday present for dad. AKA DancesWithSandyBottom in Watertribe. Happy Birthday to the best Dad ever. 


Another Race to the Start Line?

Well, ok but not quite. I wanted to get another blog post done before I won't really have time. I have updated the photo album to the current day with 174 additional pictures so check them out here. The sailing canoe is painted and almost ready for paddling/sailing trials. Mast, sail, crossbeams and amas all are nearing completion. Soon I will be on the water doing some sailing, paddling and rescue drills.


A note on safety:
I will not be entering the race (the UFC in this case) unless I have time to sail and paddle the canoe in all of its configurations and complete rescue practice with simulated failures (missing ama/crossbeam) in all configurations. I would be literally "risking my life" if I was not able to regain control of the canoe in the event of capsize. Everyone should do rescue practice before going out of reach of help.

Now, I know what your thinking....Yes, my dad and I launched our CS-20 in 2008 fresh out of the workshop and into the Everglades Challenge but we were a 2 person team and the CS-20 design was well founded and well established. And yes, I did launch a 22' Trimaran in 2012 fresh out of the workshop (sailed only once before) and had some issues with it along the way. But it was also a 2 person team and we did not push the boat very hard. This year is the first year I will be sailing solo and in a smaller craft. For that reason, I am more cautious even if my mother is convinced otherwise (love you mom).

Getting back to the build, here is a little more info about how the design has evolved and some of the systems.


Then (above) and now(below)

Hiking vs. Sitting:
Originally, the idea was to use a relatively narrow beam and rely partly on hiking benches with ama backup. The advantages would be less ama interference with the water which would make the boat more upwind capable (that was the thought process anyway). This idea was thrown out mainly because it is not conducive to distance sailing. The new platform is about 11' wide with amas of approximately 70lb displacement. If there is time I will experiment with a hiking board which would be clamped transverse across the cockpit to allow for sitting up and out of the cockpit making for a dryer ride and more righting moment. 

Crossbeams:
The crossbeam consists of 3 pieces of aluminum tube joined with fiberglass collars for a slip fit. A central tube (purple) with smaller tubes outboard (green). This is the best configuration for strength rather than joining the tubes in the center and it is a more efficient use of cross sections because it is a better approximation of a tapered beam. Another unique feature is that the central tube can slide from side to side with 3 configurations. "Centered" in which the amas provide equal righting moment on either tack. Or "Asymmetric" either shifted port or starboard. This will come in handy on those loooong tacks down the coast because with the leeward ama slid farther out producing more righting moment, the boat will sail flatter and stiffer. An added benefit of this feature is for camping, the crossbeam can put in the asymmetric position to provide a platform for camping aboard that will not rock back and forth with every movement of the sleepy sailor. 

Amas:
The amas are sculpted from solid 2lb density 2" blue foam fiber-glassed on the outside. They are approximately 8" tall by 6" wide and 63" in length. They easily fit inside the forward part of the main hull through the circular hatch. There is enough room left in the forward section for lots of gear. Mast and crossbeam tubes will also be stored there when in the paddling configuration. 

The amas will join to the crossbeams with a bracket that consists of a tube that slides onto the outboard crossbeam connected to a set of vertical "ears" and a saddle that matches the contor of the ama. The bracket will be bolted to the ama. The bracket must be removable so that the ama can be stored inside the main hull.

The bracket allows the ama to freely pivot about the axis of the crossbeam, a feature pioneered by Meade Gougeon and applied successfully in his sailing canoe. Limits for the ama's rotation will prevent the ama from rotating past about 5 degrees. The center of bouancy of the ama is slightly ahead of the crossbeam so that the ama will want to pitch up when pressed. 

The Mast:
The mast is constructed of 4 aluminum tubes the longest of which is 5 feet. Similar to the crossbeams, the mast is joined using the B&B system of fiberglass collars sanded down for a slip fit. Button clips will secure the tubes together and keep them secure. Each mast tube will have a foam plug glued into the ends so that each piece is individually buoyant.

The Sail:
The sail is a stock Spindirft 9 sail from the B&B inventory which comes with a single slab reef designed for single line reefining. A second reefing point will be added as a "deep reef" to satisfy the reefing rules. The sail has a zippered sleeve luff which is desirable for reducing drag. The sleeve is cutaway for the first reef. This allows the first reef to be put in in a matter of seconds by lowering the halyard to a predetermined spot and pulling in the single reefing line. The second reef will require unzipping the luff to the new tack position, lowering the sail with the halyard and pulling in the second reefing line.  

Portage:
The portage cart is made of a 2" aluminum tube with stub axles. The wheels are 16" utility wheels from northern tool. The cradles are homemade and bolt to the aluminum tube.


The folding bicycle is a Vilano Urnaba single speed coaster hub it was a great deal found on amazon. Total weight is 21 lbs. The stock bike came with 20" wheels. I replaced them with 16" wheels by Avenir. Front and Rear. The smaller wheels lowered the pedals to within about an inch and a half to the ground but the bike is still easily ride-able and I can't make sharp turns with the boat in tow anyway. I also purchased some larger sprockets to replace the 16 tooth one that came stock. A 22 tooth sprocket was still too high of a gear (this is the configuration in the video above). A local bike shop did a great job installing a new 44 tooth crank in the front to replace the 57 tooth that it came with. Now the gearing is nice and low. About 6mph at a cadence of about 80 to 90 rpm.

Coming Along Nicely

Even with a boatload of other projects going, I managed to get some more work done on the new sailing canoe over the last couple of weeks. Yesterday I glued up the rudder blank. The full gallery of build pictures can be seen here. B&B UFC Canoe build.

The hull is now all glassed and ready for paint but I will be finishing up the hatches and rudder before that. Then she will be paddle-able while I complete the sail rig.

I made my mast step with some leftover carbon sleeve from Graham's EC22 masts. It was not necessary but I wanted to experiment. I was able to lay up the tube with the bottom portion masked off which allowed me to glass the tube to the hull with a big carbon flange after the tube cured.  Below you can see the tube installed.



The bulkheads were finally glassed in with some bias cut glass scraps. I'm using 4oz S-glass throughout. The extra cost is justified because it is a small boat. Almost all of the scraps leftover from glassing the hull go to good use.

The deck is attached to the hull with hot glue and small wood bits which allow the hull and deck joint to be precisely joined. Once the deck and hull were joined, the inside was glassed with thickened epoxy and 2" glass tape. I used tape in the ends of the hull because it is easier to roll and unroll in place than cut strips. Once the interior hull/deck joint is fully glassed, the blocks are twisted off and a small chisel was used to gouge all of the hot glue out of the joint on the outside. Then the outside of the hull was given a good sanding and all remaining voids were filled. 


The inside is glassed. 

The bottom was glassed first and the glass was trimmed just past the hull/deck joint. It took 2 pieces to glass the bottom and the joint was left offset from center just to more efficiently use the glass. Then the deck was glassed all in one piece. That was tricky. Peel ply was used all over. I am undecided if it was worth the extra work but I believe so. 


The completed hull glassed inside and out weighed in at 43lbs.


The forward hatch I decided to do rounded for extra strength and a nicer look. Originally I planned to just bend 4mm plywood but decided to do a striped top which won't try to spring back and won't require beams underneath. The strips are 3/16" basswood 1" wide with a 5 deg bevel cut on one side of each strip. The top will be sanded round and then the hatch rim put on in plywood before glassing top and bottom. 

The stern and cockpit hatches are 4mm plywood flat panels with bent 4mm ply rims. A heat gun was used to "dry bend" the plywood. Long clamps and patience are required to achieve the hatch below. A plywood strip on the outside takes care of the end moment at the bitter ends of the joint. Once it's in place, a fillet is applied to the inside and then the screws can be removed. 



The rudder blank is glued up and will be CNC machined to shape.

A busy year to say the least

Not having any one project that I'm spending all of my time on lately I figured I would just mention them all. Here in no particular order is what takes up almost ALL of my time. To say these projects are enjoyable is an understatement.

Continuing progress on the new B&B Yacht Designs website

I've been working on a 28' Cruising Trimaran for Kayakman7 and wife Kristen.


The Core Sound 17 and 20 Mark 3 designs have evolved and work will resume on their construction manuals soon. Lots of great pictures coming in from the first builders. 



Design work continues for a 56' Carolina Sportfish. 

Design work has begun for a 61' sportfish catamaran which dwarfs the 45' powercat that B&B built over the last 4 years. Don't worry, we aren't going to build this one. 

Design of a NEW Carolina flare bow powerboat that B&B is offering. This one is going straight to kit with 2 maybe 3 builders patiently waiting for her completion. 

We also have builders patiently waiting for the completion of the Kit version of the Outer Banks 20. She is close to being cut out.

Wait there's more....

I've been slowly building a sailing canoe on the side (yes on the side of all of these projects). This will become my entry into the Ultimate Florida Challenge race next March.  
 


On the list of projects I want to finish there is also the last few videos in the series I started about building the Core Sound 15. I still mean to finish them. Occasionally I get a message asking where the next part is. Sorry. 

That's enough projects for one post.

First (non-race) Springtime sail of the year

Yesterday we made it out to B&B for a relaxing sail with the dog which happened to be her first time out in the sailboat. I have taken her out in the rowboat before but she didn't seem to enjoy it much. We hope the warmer weather will encourage her to do some swimming out at the shop and be more comfortable around water. She had a great time on the boat smelling the smells, checking the sail trim, patrolling the creek and eating treats.

B&B 45' Powercat travels from Washington, NC to New Bern, NC

The past weekend I had the opportunity to crew for the owner of the Powercat 'SiverVoyager' that was designed by Graham Byrnes and built by B&B Yacht Designs. I have personally spent about 4 years full time on the built team. She was put up on the hard to have the props re-pitched and as well as add a wedge and side fences to the transoms. The reduced pitch increased the full throttle engine RPM at the manufacturer's request. The fences and wedge were added to trim the bow down slightly. Initial sea trials showed about 2.5 degrees of bow up at cruise in flat water which was reduced to 1.5 degrees. At 15 knots it's like a magic carpet. Just an incredible feeling of speed. Videos below.


Lifted and on her way to the basin.

View from astern. Transom fences clearly visible. 


 Another view of the transom fences. The discoloration is thanks to the Neuse River.
"Neuse Juice" as we call it here. It will fade once she gets into some clear water. 

 Passing a barge just before the Hobucken Bridge. 

We left Washington Yacht Service harbor at 1:45pm in the rain and tied up at 8:15pm. Total trip distance was 71.5 nautical miles. Average speed: 11 knots. The wind was 15-20 knots out of the SSW which made for about a 4' chop at about 20-30' wavelength in the mouth of the Neuse. In these conditions we slowed the boat to 9 knots for extra comfort. The high wing deck clearance that Graham made no concessions on in the design proved it's worth again and again as we glided directly into the head sea. The motion was easy and smooth compared to the sea state outside.

Graham met us on the Hobucken Bridge over the ICW to get some pictures and video of his masterpiece from above. I will try to get a copy of his pictures and post them here.


Below, shot at the mouth of the Neuse River. Boat speed is 9.5 knots. Head sea just off the port bow. 








As we made our way south the fetch was reduced and we were able to resume 15 knots cruise speed. Please forgive the brevity of the video, I was standing up to a 30 knot apparent headwind. 



Finally this is the wake at 15.5 knots. The fences and wedge improved the flatness of the wake. Overall very little wake considering the speed.

2015 Everglades Challenge Race Report

This years Everglades Challenge was one for the record books. Many challengers this year had personal best times into Checkpoint 1 at Cape Haze Marina where the event was officially canceled.  My Dad (DancesWithSandyBottom) and I tied up at 3:59 pm which happens to be 10 minutes FASTER than we did in 2013 and just 12 minutes after Jake (Poptarps) and I came into CP1 in 2014 in the Mosquito Trimaran. In short, we had a blast sailing down the outside this year and decided to quit after CP1. For the long version continue below...

As I posted earlier in the week we had just completed the retrofit of our new weighted centerboard of proven design into our CS20 'Dawn Patrol' and we were really excited about its potential to improve life aboard especially at speed. Other changes to the boat this year included improving the design of our spray deflectors along the side decks and lowering the spinnaker halyard block and raising the running backstay connection to reduce mast bending under the load of the spinnaker. All of these changes were huge successes especially the centerboard which we found to be vastly easier to use in shallow water and which made grounding much less of a scramble to raise the board which used to be held down by shock cords. Now the board just gently raises and slows the boat very little as it drags the bottom until it is hoisted.

On race morning we completed final tasks before heading over for the roll call. Sails hoisted, SPOT on, gopro mounted, rollers inflated, and a walk out into the water to check the depth of the sandbar about 20 yards off the beach. I thought we might need rollers to get over it but we ended up floating right over.

We had checked the forecast and knew to expect about 15 knots out of the NE and for us that meant a deep reach across the bay to Passage key and then out into the gulf. We know our boat pretty well and knew that we could easily handle full sail for the conditions in front of us and did not put in a reef. I noticed that others were reefing for the start, a decision that is up to the captain of his or her vessel based on conditions and experience. We were at the west end of the beach flanked by an I550 and Ridgerunner and Greybeard in their CS20 Mk3. At 7 am we heard Paula giving the all clear to launch and we made fast work of getting to the water. With one long push we rolled over our 3 inflated roller and down the beach sliding the last 10 feet over wet sand and finally into the water. We collected our rollers, threw them into the cockpit, and were off on a reach gliding along in the relatively flat water just off shore.

Just before launch. CS-20 Mk3 at left.

I looked back as we gained distance over the pack. I think we were one of the first Class 4 boats to get going but we knew we would almost certainly be caught up by Graham's EC-22 which was chartered by Chupacabra and Flysonwater. Sure enough they were about even with us about half way across the bay. We never thought twice about the conditions or that anyone else would be struggling to get across the bay at that time. We were occasionally surfing down the swells and averaging about 7-9 knots with bursts up to 11.

Halfway across the bay. EC-22 to starboard. 

We were sailing close to Coastie and Clamcounter on their Hobie Getaway as we made our way to the inside of Passage key. They had their sail slightly eased which allowed us to just about match them for speed. We made the jibe together into the pass that lead to the gulf. The EC-22 had chosen to leave Passage key to port which gave us quite a head start down the coast as we entered the gulf hugging the beach. We jibed again onto port where we would stay all the way to Stump Pass. We could see the Class 5 leaders out ahead becoming specs on the horizon as expected.


Sailing with Coastie and Clamcounter on Hobie Getaway.

We did our best to hold off the EC-22 but it steadily gained and then passed us again and then eventually disappeared from view. They arrived in CP1 1 hour ahead of us. We knew we couldn't keep up with them in these conditions but we also knew that it was a long race (usually) and that reaching downwind won't last forever. I hoped that lighter conditions in the coming days and the natrual filters the course offered would favor us in the end. We know full well that the narrow winding route into and out of CP2 can bring challengers back head to head with one stroke of the tide. Florida bay can grab your bottom and not let go for hours or even days so it's never over until it's over but i guess we will never know.

I saw a CG chopper headed south and remember thinking I hope nothing has happened to anyone out ahead in Class 5. Later we saw what I assume was the same chopper headed back toward Tampa. On our way South we were also passed by Gadgetgirl in her tricked out Weta trimaran. She had a reef in and was sliding right by us. I got some gopro footage of her as she passed. A few hours later she was out of sight.

Gadgetgirl Sails past. 

We were about 25nm from Stump Pass where we would enter to reach CP1 when my phone rang. I left my phone on in the cabin because we carry a house battery on board with a 100watt solar panel on the cabin roof and can easily charge our phones during the race. The battery also powers a tiller pilot which we use in light air and while rowing in dead open water. The caller was Steve our shore contact who did a great job and posted about us on his blog 'Log of Spartina' keeping tabs on us during the event. He left us a message relayed from Kayakman7 that the CG had made numerous rescues in Tampa bay and was putting a mandatory weather hold on the event and that we were instructed to seek safe harbor immediately. After discussing the meaning of the message and calling Steve back to confirm we made the decision to seek safe harbor at CP1 by way of Stump Pass. We altered course to close our distance from the beach to less than a mile and took stock of the situation as we read up on the happenings in Tampa bay via facebook posts and the watertribe forum.

The wind had started to lighten to about 10 knots as we ticked off the final miles to Stump Pass. By this time we had read the CG bulletin indicating that they were "terminating" the event due to the rescues and the deteriorating conditions and at about that same time the sun came out and the wind lightened even more. We tacked into Stump Pass on a slight incoming tide. At that point we considered the option of simply sailing right on by CP1 and continuing our vacation to Key Largo but thought it would be a good idea to call the CP1 manager first. Izatarock thought that we should come in to the CP anyway since it wasn't clear at that point if the event may be allowed to continue and also they had pizza. We tied up at 3:59 pm and proceeded to the Pizza.

Tied up at CP1. Where is the pizza. 

At 5pm those challengers that were at CP1, some of whom had been waiting for hours, were ready to make a decision regardless of what came down the pipe and together all challengers attempted to agree on how to proceed. In the end, most wanted to continue but many had no interest in sailing all the way into CP2 or CP3 except maybe to refill water. We basically decided to all do whatever we wanted regarding the actual EC route and knowing that if the event was officially restarted we may all be officially disqualified.  Shortly thereafter most departed CP1 including us and the EC-22. We knew at that point that SandyBottom had stopped for many hours on the ICW and that she had decided to possibly continue at a more relaxed pace and not plan to make Key Largo by kayak. It was clear that many challengers were wrestling with the idea of continuing anyway or calling it quits to save vacation time and money on hotels booked at the finish.

Chupacabra and Flysonwater on the EC-22 indicated to us that they would likely stop to camp at Sanibel on the south end of Pine Island Sound. They planned to probably skip CP2. We made our way south and sailed under the Placida harbor swing bridge together with them with a few pulls of the oars. The sun was setting as we picked up speed into the open water of Charlotte Harbor and the EC-22 began to leave us behind. In the darkness we avoided day markers now almost invisible as we splashed our way across the large fetch of the mouth of Boca Grande inlet. We were getting wet, it was getting colder, we were depressed and still in shock at the events of the day. This was not fun and so we decided to camp for the night in Pelican bay. We settled into a sweet anchorage and read up on all the latest posts. By morning we decided it would be more fun to just sail back to Tampa where we could take the boat out and then go retrieve SandyBottom. We sailed out Boca Grande and started north where we took stock and realized that it would be well after dark before we would arrive at the Fort DeSoto Boat ramp so we just sailed right back into Stump Pass and back to CP1. We caught another incoming tide and tied up at the marina right at noon on Sunday just in time for the makeshift awards ceremony for the Ultra Marathon which i guess technically wasn't "terminated". There we had hot dogs, beans, and potato salad. You may note at this point that we have managed to eat almost none of the food that we actually brought with us in the boat for the event.

By this time SandyBottom was being picked up by Kiwibird and together they would meet us at CP1. We spent the remainder of Sunday talking with watertribers at CP1 about what had happened and trying to salvage the time we had with each other. Many were planning to just head home at that point and we would do the same. We were on the road Monday morning headed back to NC.

I have tried to keep up with all of the posts on WT, facebook and SA but for the most part will sit out of any online discussion until more facts are published and the Chief has had the opportunity to speak to the CG on our (watertribes) behalf. I know that this years stumble will only strengthen and improve the everglades challenge an the watertribe organization as a whole. I look forward to future discussions on how we can all better plan for and mitigate the effects of weather on our small boat events as well as improve the process by which challenger preparedness and the security of their chosen craft is evaluated. I do not fault the CG for their abundance of caution although I believe that this event could have safely resumed. I thank them for aid rendered to any triber and try never to forget that I may well really need them next time.

Dawn Patrol gets a new Depth Indicator

Also known as a centerboard. This year we finally got around to switching over to a weighted centerboard. 31lbs all up including the lead in the tip. The uphaul line is a 10:1 cascaded purchase and the top of the trunk is now covered in a 6mm piece of lexan. There is a small block that angles the uphaul out of the side of the board and back into the cockpit. This is sealed with a plywood box and lexan cover and a pvc pipe to lead the line aft.

The biggest advantage of this system over the old is that at high speeds (10 knots plus) water would siphon up the trunk and spill out sometimes forcefully like a geyser into the cockpit and the cabin. On several occasions this was a rude awakening to the poor sucker trying to sleep in the cabin. The only solution was to stuff sponges into the top of the trunk which kind of works but eventually they are ejected and they hinder movement of the board. Here are some pictures of the new setup.

Video Editor? more like Profanity Producer!

Just finished part 19 in the building series on the Core Sound 15. The prototype that went to a customer in Florida was completed almost 4 months ago but if feels like i haven't had a spare moment to work on videos since then.

Well, this weekend I forced myself through another segment using a new program which always takes longer. I'm now using Power Director 13 which was a Christmas gift! (thank you Dad) Using windows movie maker was really a drag with the large files I'm working with. The raw files for this video are around 10 GB and the finished video came in at 2.3 GB rendered at 1280x720. All video and audio was taken from my Samsung Galaxy S5 (same as all the other videos) which is also my everyday phone.



Below is a screenshot of Power Director. It has waaaay more features than i need and I actually had to look pretty hard to find settings that would kind of match the sort of outdated look of the old videos so that the series would kind of match but the speed of the program is at least 4 times faster maybe more and rendering takes a fraction of the time. It also has many features that I'm sure will come in handy as I become a better producer.
