#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.

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!

#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   17 downloads

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.

I talked with Graham this afternoon.  Carla is back in the hospital with what ever the infection is she has.  It is making it rouph on Graham.  You can tell in his voice he is worried about his wife.  He is a awfully good man to help us build our boats and take time to talk to us.  We need to pray for him as well as Carla.  When ever I go work in the boat I just stop and pray for both of them and I can not wait till I hear she is home and on the mend Stop for a moment and pray for both of them

Thanks again for all of the well wishes. Since yesterday there has been quite a turn around. She is starting to eat again and able to keep it down.


We are quite optimistic.

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...

#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.

#78489 Epoxy Tricks

Posted by PAR on 14 February 2014 - 09:03 AM

Long boards come in various shapes, lengths and sizes, usually geared to match the job. A 1/2" plywood board is too stiff for most boats, except in large expanses of relatively flat areas. I've got a number of boards, one of my favorites is made from 1/8" Lexan. It's 4" wide, about 20" long and fairly flexible, so I can work compound curves. I have ones that are 1/8" and 1/4" plywood too and even one made from 14 gauge aluminum sheet. I buy paper on rolls and cut to length, using a spray adhesive to mount them, though you can just as easily use a clip or slot at each end, to hold the paper to the board.


Technique is key with a boogie board (board-'o-pain). Typically you work from one end of the area (or hull side) in a single direction, across it's full length. You select an appropriate angle, which often seems to be about 30 degrees to the centerline and stroke the board at this angle the full length of the area. All strokes are at this angle, leaving a series of angled scratches. You then come back at the opposite angle, in the other direction, netting a cross hatched pattern of scratches. The low spots will be clearly visible, not having scratches in them and the high spots will be knocked down a touch. At this point, you mark the low spots and apply a little filler in these areas. The next pass with the torture board is focused on the now filled low spots, so you can knock them down to surrounding areas. I often use a very light dusting of primer at this point to fine tune the surface and help see what needs what. Again, working a common angle, you run from one end, to the other, placing a new diagonal scratch pattern and come back on the reciprocal angle for the cross hatch pattern. Each pass will continue to knock down the high spots and reveal the lows you've missed on previous passes.


A pro will make three passes with the cross hatched, long board pattern. The first to find the lows, the second to knock the lows back once filled and the final pass, to even everything up. The backyard fairer, can make a career out of this process, with many passes and filling sessions. The more you work this set of steps, the fairer and smoother the hull will be. The same process is used with paint, if you want a baby's butt surface, just with finer grits, usually wet. It helps a lot to have the right lighting for this process. You can have too much light, particularly if it's directly over head. You want a low angle of light, so you can see the shadows in the low spots.


The biggest mistakes novices make are not using a long board, thinking a palm sander or orbital will do and over working the surface. The Harbor Freight "in line sander" linked above shouldn't be used. It will remove material at an alarming rate and it's not flexible enough to conform to curved surfaces. That particular Harbor Fright tool is a single piston design and you'll be in serious pain, with just a 1/2 hour of use. It's a real piece of crap and if you want one, get a duel action/piston design so it doesn't tear your elbows off. Try not to get aggressive with material removal, just lightly scratch the surface, so you can see what's high and what needs to be filled. On plywood hulls you'll bring the lows up to the highs for the most part, so skim coat the lows with some filler and knock these filled areas back locally at first, then with the long board passes. A jitter bug (palm sander), DA or orbital sander will not fair a surface, just smooth it. Fairing and smoothing operations are wholly different. The long board fairs. Once the surface is fair, then you can move onto smoothing operations. Fair is what you can see, while smooth is what you feel. A surface can be smooth, but quite unfair. A dent in a car door is a classic example of this. The dent can be polished and really smooth, but the light reflection will clearly show it's not fair.

#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.

#76151 Sailing video of our CS20

Posted by wkisting on 26 August 2013 - 11:27 AM

Hi David,


I use a loop of bungee that attaches to a hook on the underside of each hatch cover. I spent a long time dreaming up other solutions because for some reason I didn't like the idea of using bungee cording, but once I finally tried it, I was impressed how well it holds the hatches shut (once you get the length right for proper tension) and yet how easy it is to stretch to unhook the loop and open the hatch. It's simple, cheap, and works great--especially for how rarely we need to access the fore and aft compartments. (I only stow the anchor in the forward compartment, and lifejackets and a few floatie chairs in the rear one.) I certainly like the "uncluttered" look of having no latch mechanism visible on the outside of the hatch.

Posted by Scott Dunsworth on 05 November 2011 - 08:23 AM

Here is one more video, my wife didn't get to go with me so it's from the boat also. Doing 6 to 7 mph with one reef in. I had the the recorder strapped to the cabin top for about half of the clip so its pretty boring. I did get some over the transom and down the side of the boat. Remember I carry as much as 800 lbs of stuff in the boat so performance is hampered a bit. Scott
