I have used this feature a number of times.  But today I saw my first like by someone else.  I can't say no one else uses this feature, but as thoroughly as I read this forum I can't imagine too many likes got past me.  The most common reasons I have for using the like feature is to show support for a good technical post without saying the same things again when some one else has already said them well in the first place.  Also I use it to simply provide a positive reply for cool pictures and acknowledge that I enjoyed them.  Anyway, I just thought it strange how little the feature is used.  Not to imply written replies need to be limited, just a curiosity of mine.


#88819 Future of B&B Yacht Design

Posted by Garry on 20 November 2015 - 04:21 AM

I may have missed other posts relating to future plans for B&B Yacht Design, but I noticed this entry from Graham on another thread and thought that it deserved it's own thread.



After the completion of the cat we had to decide where the company was going. I could have carried on with Carla doing as much as we could but slowly grinding the business into the ground as we aged out. We had long recognized how good Alan was and decided to offer him a partnership. Earlier this year we formed B&B Yacht Design inc. with Carla, Alan, Beth and I as equal partners. As Carla and I age out they will take over and eventually inherit the whole business.


We kept Nat on to help out and David is doing most of the machining giving Alan and I more time to create. I see B&B growing a lot more in the future. It gives me a lot of satisfaction to know that the business will live on and that the builders who had enough faith to build our designs will know that they will continue to have support and keep up the value of their boats.


I want to applaud Graham and Carla, first for their commitment and innovation to boat design and building, and second for their foresight and good fortune in bringing Alan and Beth into the business. I also want to thank and congratulate Alan and Beth for keeping this wonderful enterprise alive. 

#82505 Carla Byrnes

I talked with Carla yesterday. She is doing MUCH better. She is off of anti-biotics now and the infection is gone. She has 5 sets of plates, screws, and rods in her neck, but---this is hard to believe---she has a full range of motion!. And NO PAIN! She is able to eat normally now, and it "all comes out the way it is supposed too." She has lost a lot of weight through her ordeal. She feels good but is still very weak. Her main job now is to build up her strength and endurance to the point that she can begin physical therapy. She still has more surgery to come on her lower back. (Still pain in her lower back, That was where she was originally supposed to have the surgery until tests indicated a very dangerous situation in her neck.) This will happen, maybe, in December.


She is back in he office trying to get everything back on track---including Graham. Her computer went down just as she got back, and they went through a period when the phone system was "off line". Who did I just hear saying "When it rains, it pours."? Beth was a great help in getting out plans and such.


Carla is very thankful to all of of you for your concerns, well wishes, and prayers. She said that there were literally thousands of people, church groups, and friends praying for her, and she credits this for her recovery from a very dangerous and trying situation. Thank you to all of you. And most of all, thanks to God!

I felt like it would be a good idea to intentionally capsize my boat in a controlled environment so I could practice righting the boat. I also wanted to observe to see if there were any modifications I could make to insure that the boat was stable when it was knocked over and I would be able to right the boat.


I kept putting this little chore off. I didn't want to break anything. I did not have anyone to help me. I did not want to injury myself or someone else.



My nephew was visiting, there was no wind so we decided to give it a go. We both gained some confidence learned a few things and had some fun. And nothing got broken.



#91125 Tips and Tricks

Posted by PAR on 17 April 2016 - 08:02 PM

When applying goo and fabric overhead, a builder with a significant bald spot has the advantage of using it as a squeegee, to hold and smooth the cloth, without the usual bad hair day. Apply a PVA first for easier clean up afterward.

#89919 Keep the weight down

Posted by andy00 on 31 January 2016 - 05:45 AM

Missing from this discussion is analysis of failure modes. We need information on how SOF boats have failed:

  • Did a stringer break? At a frame? Between frames? At a knot? At a joint? What species of wood? Dimensions?
  • Did a frame break? Where? What type of plywood? Dimensions?
  • Did a lashing or other fastening between a stinger and frame fail?

This forum might be a way to collect some information of this sort. Then some ideas on where weight can be safely reduced and where to keep things robust can be developed.


Paddle on, Andy

#89259 Tips and Tricks

Posted by Rich D on 15 December 2015 - 04:44 AM

Winter Storage:

Not a building tip but I thought this tip might be useful for those who keep their boats outside during the winter. 

When I removed the old skin on one of my kayaks to do a re-skin job I found that mice had built a nest for the winter up in the bow end of the boat and had gnawed about half way through a couple of the stringers. 

   I remembered that when we owned a travel trailer my wife would put dryer sheets in cupboards, drawers, and corners to repel the mice. In many years of outside storage we never once had any sign of mice in the camper. Now I push a few dryer sheets into each end of the boat while I wait for soft water again. Seems to be working.

Hi everyone,

Good day to everyone we are joining from south cost of Turkey. We two amateurs we start to built OC 20 and any comments negative or positive highly appreciated..

Thanks to everyone and safe voyages.

I should say from this part of the world Graham and Carla they are both great people and they are very helpful.Attached File  image.jpg   216.88KB   7 downloadsAttached File  image.jpg   179.14KB   4 downloadsAttached File  image.jpg   206.28KB   8 downloadsAttached File  image.jpg   190.87KB   8 downloadsAttached File  image.jpg   184.51KB   6 downloadsAttached File  image.jpg   179.72KB   8 downloads

#86573 New sail track

Posted by Designer on 14 June 2015 - 07:52 AM



It is not hard to drill out the rivets to remove the old track and it is fairly easy to remove the old slides and sew on the new ones but it is tedious. The expedient way would be to just shackle the slides to the sails, I prefer the webbing method.


That being said, I do not expect everyone to rush out change their tracks because it does work, just not as smooth.


I am going to change out Southern Skimmer's track, I am using the excuse that it is R&D.




I think that it is a good idea to supply the rivets with the track. We are sending one of our rivets to the machine shop to make sure that it is a match.


Howard, I do not think that aluminum rivets are strong enough. I know that you are thinking about corrosion. If you put some goop on each rivet it helps. SS and aluminum are not far apart on the galvanic scale. You always want the fastener to be slightly more noble than the mass so that it will be protected. Aluminum on aluminum will corrode if it stays wet.


I will be caulking the track to the mast as well just to keep moisture from corroding under the track.

#86558 New sail track

Posted by Designer on 13 June 2015 - 10:19 AM

It has been a long time coming. I have never been happy with the stainless steel external track. Until now it was the only track available.


Many years ago, I used to be able to get 5/8 and 7/8 internal track. I have searched long and hard over the years and finally got back to the company that had the original die, but I could not justify the huge cost to do a run. I do not even think it exists anymore.


I even modified some cutters and machined some track out of Starboard. It worked very well but was labor intensive and it was a bit bulky.


Alan contacted about 10 aluminum extruders and so the work began. We decided that over the years we have used enough track to make the big investment.


We began to list all of the properties we wanted and probably drew hundreds of versions before we committed. We wanted it to be strong enough for a 30' boat, but light enough for a Core Sound. The last weekend that I worked on it I was able to save a few more hundreds of an ounce per foot. We realized that we had better get it right or we would have the worlds most expensive recycling.


We took a deep breath and invested in having the die made.  The company just sent us a 3 foot trial sample, to evaluate before we make the big run.  We are really happy with it; it is everything we wanted and hoped for.


It is made of 6061 T-6 aluminum which is the same as the spars, so there is no galvanic interaction. It weighs 2.7 oz per foot. The track is clear anodized and pre-drilled for 5/32" countersunk rivets, or #8 flat head machine screws. It also has a V-groove down the center, so if you want/need to add and in-between fastener; or an end of section faster, because your cut length is not at the end of a standard length.  It is has a radius on the back side to fit from 6" down to 1 1/2" round spar tubes. It has flat on each side of the edge on the back, so it will also fit flat on a wooden mast, with round or flat sections (box sections).  It is much stiffer and straighter than the SS external track and it fits true to the surface (doesn't tilt off), which makes it easier to install.  The corners are well radiused to prevent chafe on the sprit.  


It takes standard 5/8" internal nylon sail slides.  The slides slide more easily than on the external track.  


The best thing of all is that with all these features and advantages it will cost less to our builders (or others) than the ss track.  We expect to be able to sell it for about $35.00 per 8' length; vs.  $39.00 for a slightly under 6' section of ss 5/8" track.  After a lot of soul searching, we decided on 8' lengths so we can ship FedEx.


The picture shows the track on a 1 1/2" tube with a nylon slide.Attached File  sailtrack1 (790x665).jpg   58.77KB   18 downloads 

#82135 Carla Byrnes

Posted by Designer on 04 September 2014 - 09:26 PM

Thanks again for every ones wishes and concern. Carla was released on Monday and tonight she looked the best that she has been since the surgery. She has been up and down before but if she does not slip back over the next couple of days I am confident that she will be past the worst.

#81262 Carla Byrnes

Posted by Designer on 22 July 2014 - 06:20 AM

I want to thank everyone for their support and well wishes. Carla got out of surgery at around 5 pm yesterday. The doctor said that everything went well. Marissa and I drove home after they moved her from the post-op to a room. She as alert and able to communicate and all of her vitals looked good. Beth is staying with her. She can come home in three to five days depending on her recovery rate.


The bad news is that they were originally going to repair the upper and lower spine at the same time but decided the the upper was so bad that they addressed it first and she will have to go back for a second round once they deem her to be ready. She will be convalescing for a long time.


Marissa is home from college and will be running the office as best as she can. I want to thank everyone in advance for their patience.

#80084 Converting "Fly Fisher" into a sailboat.

Posted by Action Tiger on 08 May 2014 - 11:36 AM

I will second those Core Sound boats. Lots of boat, there.
Also, Richard, people DO build SOF sailboats. They also build sailboats from plastic bottles, and concrete.
Dave is right about a good sailboat. It makes sailing fun. So do good sails.
I have built some turds.

Don't break too many rules until you learn them fairly well.

That pointy triangle boat looks like a death trap. I'd want my buoyancy further forward.

Then again, what do I know? I never listen. Just ask my mom, or wife, or kids...

#79963 Another ok20 build

Posted by glm on 01 May 2014 - 03:14 PM

Hi Matt
I have glued the last layer on my keel today, just about done. As far as the stem goes, I have as many as 3 joints in the 3 layers. As long as you stagger the joints as much as possible you should be good. I glued the doublers on the frames as they where being fabricated. I cut the transom layers from a template, then laminated the layers on the transom jig as per blueprint. I will try to attach a couple of pictures of my keel.

#79250 CS17 mk3 and CS20 mk3

Posted by Designer on 19 March 2014 - 08:46 PM

I have just about finished making the first CS17 mk3 kit, I made the centerboard today. I am working on final tweaking and finishing up the plans and should have them available soon. There is a lot of detail and it takes time to get it all together.


I have been sneaking in a few duplicate parts so that I can have one.

#77996 CS17 mk3 and CS20 mk3

Posted by Designer on 13 January 2014 - 09:40 PM

We waved farewell to Doug today as he drove off with his new Mk3. We were happy to get her out of the shop to get a good look at her rather than being too close all of the time. I feel that she more than met my expectations and you can still see the Core Sound heritage.


There is decent headroom, without the trunk cabin. It is very comfortable laying back against the hull, at 5' 7" sitting as tall as I could, my head was not touching the deck. I think that a 6 footer could find a comfortable position.

#76714 CS17 mk3 and CS20 mk3

Posted by Designer on 04 October 2013 - 08:12 PM

Rather than hijack the mk2 thread I will start a new one.


Chick asked that I post some pictures of the mk3.


I started on a cabin version of the CS17 at least 5 years ago.  I got involved in the big cat project and shelved it for a while. One night after work I was showing Alan some drawings that never made it. When we came upon the CS17 with the raised deck, Alan became excited by it's potential.


I cyber dusted off the oiginal drawings and imported them into Rhino and modified them a bit to fit my current thinking. Then I thought, this might work on the CS20. The CS20 mk3 was born. Here are a couple of views of her.
