Videos from the B & B Messabout 2014

In the above video, Robert and I attempt to chase down the CS20 MK3. She is a fast boat!

Later the new MK3 CS20 sucessfully completed a self righting test with ballast tanks full.

For comparision here is the self righting test done at the 2013 Messabout in the Core Sound 20 Mk2 that recently completed the North Carolina Challenge 2014.

B&B Messabout (Sunday)

here are some pictures I took on Sunday. I also created a Facebook group for the B&B messabout with many more pictures that can be seen here.

A lineup of CS's (my 17 'Southbound' then the new CS-15 'Amazing Grace' then 'Dawn Patrol' and on the end I believe is Brent's CS-20.

The ever cheerful Robert jumped on board the 15 for a quick blast around the creek.

B&B Messabout 2014 (Saturday)

The Boat shed down by the waterfront turned buffet area. 

A Band even showed up!!

The CS 15 "Amazing Grace", YES IT'S THE ONE FROM THE VIDEOS!!!! Finished. More videos on it coming soon I promise...

Here she is from the stern ready to set sail. 

A happy new owner

My little puppy 'Dejah' finally worked up the courage to venture out onto the dock. 
Chicken may have helped motivate her.

A Furry Addition

 This weekend we brought home a new furry friend into our lives. Dejah is a rescue puppy picked up on the streets in Clinton, NC. She is 5 months old and has one blue eye. She is very sweet and quiet. We are loving her!
 She loves to be wherever you are.
And she loves WoodenBoat Magazine!

This week at the B and B Yacht Designs Shop in Vandemere, NC we had a misty morning and I snapped some pictures at the dock as the seagulls flew over the glassy creek.

Core Sound 17 'Southbound' gets a weigh in

This week at the shop I finally got around to purchasing a new trailer for my Core Sound 17 'Southbound'. The original trailer was commandeered for the Mosquito Trimaran and I don't want to modify it back to fit the 17.  We took the opportunity to lift her onto the trailer with the tractor and use a newly acquired digital scale to weigh her. Any guesses???

She weighed in at 445 pounds with no accessories. No masts, sails, sprits, rudder, anchor. So all up probably a 500 lb boat.

Here she sits on the new Trailer.

Mandy inspects the welds and declares them to be sound. She says that we may proceed. 

The trailer needs a little adjusting as there is a bit of overhang at the moment but all looks good for many more sailing trips to come.

Starting to look like a Boat

This weekend I glued in the tabernacle assembly and the mizzen mast bast. I also got some work done on the foredeck and the carlins that will support the side deck. Here are parts 12 and 13.

More work on the Core Sound 15

I've uploaded parts 9, 10 and 11 of the build. If your one of the 3 people who can stand to watch them then thanks for following along! These 3 videos represent about 2 long weekends (or about 5 days) worth of work.

In Part 9 below I get the aft seat locker painted in preparation for the seat tops going down. I also get the centerboard trunk glassed to the bottom of the hull.

In part 10 I get the seat tops glued down. I made a piping bag (apparently that is what they are really called) to do the "icing" on the "cake". Don't make the mix too thick or you will have trouble squeezing it out of the bag easily.

In part 11 I was able to get a lot done thanks to the 93 degree weather we had this weekend. Multiple steps were possible in 1 day because of the fast gel time of the epoxy at that temperature. I coated the seat tops and sanded them the next day, installed the tabernacle bulkhead and glassed it in and I also started coating some of the underside of the various deck parts off camera so they will be ready to go down when all the deck structure is finished.

Core Sound 15 Centerboard Construction

Below is a video of the process of cutting and gluing up the quarter-sawn strips of wood that make up the centerboard. The finished blank for the centerboard is very stable because we "end for end" every other strip in the board which cancels out the bending or twisting tendencies of any individual strip. The strips are oriented as close to quarter-sawn as possible to reduce the effects of expansion and contraction of the wood.

Ideally this process starts with a straight plain-sawn board with little twist. The boards I used were not as plain sawn as they could have been and so I ended up with some strips that resemble more rift-sawn cuts. One could be more picky with their strips and weed out the rift-sawn ones.

After the blank was glued up it was put on the CNC machine to be shaped. The creation of the part files takes about twice or even 3 times as long as the cutting itself. The entire process took about 6 hours to draft the centerboard in 3 dimensions and create the cutting files. That includes the surfacing and hole drilling and outline cutting. Each of these processes involves a different set of menu options in the software and each produces a separate file. It is not as easy as throwing in your 3d model and out pops a centerboard. Each file has to be referenced correctly to the origin so that all the cutting operations happen in the right spot in relation to all the others. Otherwise the two halves of the board might not match up!

Here is a video of the processes that went into cutting out the centerboard. The obvious advantage to this method is that another centerboard can now be created using these files in a fraction of the time. And all in all, the final product is more accurate that one could hand shape given 6 hours with any hand operated tool.

Core Sound 15 Centerboard Trunk Installation

This week the centerboard trunk was installed in the cockpit and awaits fiberglass taping. I also started on construction of the centerboard which will be the subject of the next video.

Part 6 of the Core Sound 15 build

Had the chance to get more parts cut out for the 15 last week. Here is a video of the progress to date:

Below are some pictures of assembling the B and B waterproof hatches.

The assembled hatch and hatch ring. 

This is a rendered view of the finished hatch.

Here it is seen from below. All edges would be rounded over.

Here we have an exploded view of the hatch lid. 

This is an exploded view of the hatch ring showing all the parts.

And now for the real thing.

 Here is the hatch lid being glued up on a flat table to eliminate the possibility of a twist in the top. The parts were assembled with dabs of hot glue and then filleted. The hardwood beam across the back cannot be hot glued down like the plywood sides. It must be glued down with thickened epoxy. 
Here are the parts for the hatch ring. The sides and back rail are hardwood. They were glued on after the inner corner of the plywood parts were filleted. 

Here the hatch ring parts are dry fitted and hot glued together to hold them in place while being filleted. The hardwood sides are just dry fitted.  

Here is another video from B and B last week of the crew lifting the hard top on to the 45' powercat that is nearing completion at B and B.
