CS-20

[kmrmike]

Ahoy mates! I'm a new member to the forum and recently purchased a set of CS20 plans (haven't received them yet.) I'm wondering if there are any members living in the Port ST. Lucie, FL. area who are building a CS20 or similar boat who I can contact and gain some knowledge before building. Thanks... Mike

Hi Mike,

Welcome to the forum and to Core Sound Land.

I have my CS 17 about 95% complete. I am not very close to you but if you have any questions that I can help you with, please send me an email and I will be happy to share my CS 17 building experience.

I have been so busy this summer I can't seem to get my boat finished. Oh well, our best sailing season is coming in October.

Mike- welcome aboard.

I finished a CS 17 last May for a customer and will be cranking up a CS 20 within the next couple of weeks - would start sooner but the delivery company damaged the shipment of epoxy and glass tape, so I'm having to have it reshipped.

Should you run into any problems or just want to ask questions, you can post them here, email me or email Graham directly. Also Ray Frechette builds 17s.

The 17s and the 20s are almost identical in construction.

Don't be afraid to ask the questions.

Listen to those guys Mike. They are full of good stuff. I just finished (launched) my CS 17 earlier this summer. You are going to have a really cool boat when you get through. Found myself outrunning a Catalina 22 this past Sunday. On a close reach and had the CB only half way down.

Rookie captain or something.

Thank you All for your fast response! It seems the support is out there for the asking.

Dale , I will probably be contacting you in the future to see your project, you

[Charlie Jones]

now THAT question is definitely up to Graham to rule on. Pretty significant shift. Should work fine, but I'm no designer

Wonder how the butterfly would react when you went to fold it up? Probably have to make some changes there.

[kmrmike]

OK, thanks again ! this idea is strickly tentative, I don't have my plans in hand yet and I know the cost will be much greater. It's food for thought though

[JeffM]

Mike, the cs20 is already a very light displacement boat for its length. Rather than reducing weight, I usually find myself looking for MORE weight to steady her in a breeze!

If you prefer the foam/glass, check out www.ikarus342000.com/Woodepoxy.htm Goodluck.

[kmrmike]

Jeffm, OK, maybe lighter is not better. These are just ideas i'm throwing out there for some input from experienced builders. It seems the yeas and nays favor staying with wood constriction so far. Thanks. By the way, I'm originally from Attleboro, almost your neighbor!

Isearle, thanks for the website seems they like wood too!

[kmrmike]

Point well taken Ray, suppport is definitely a plus for a new builder. I guess my composite mentality has followed me from the airplane I built several years ago . I liked the concept. Lighter is better in avaition!

[JeffM]

Airplane? Very cool! What sort?

[mustangermatt]

Ok, here I go bucking the tide again.

I did my centerboard foam and glass and so i have a few thoughts on this subject. I got some advice not to do it composite but it worked out really well. I was able to easily achieve a true and accurate NACA foil.

Lighter is definitely better in performance boats. Build it 1/3 lighter then put that weight back in low as ballast if you want, Or if you're wild and crazy add a trapeze, build stronger masts, add sail area and fasten your seatbelt :-)

Also depending on thickness of foam (like 3/4"), you're likely going to get a much stronger hull than 1/4" ply could be based on the additional leverage against tension and compression. There is a reason airplanes are built this way and not with ply (well, I guess a few have been, spruce goose anyone) :-).

The downside is that wood is alot more fun to work with. I hate epoxying things. Also we are not really talking about a coresound here since the whole concept is probably out of scope of the average home builder.

Ok, I have had my little say, let the rebuttles fly :-)

[ChrisObee]

All foam boats typically have more layers of glass and epoxy to make up for the puncture resistance that the foam core lacks. I am unsure that there would be any weight loss.

[Charlie Jones]

Graham and I talked about that today. He feels that the ply is the lighter of the two methods.

This from my own research- PLywood is gonna give you a stiffer hull too. And with the wood, that hull will STAY stiff longer. One of the reasons that high performance small sailboats are going back to wood composites- they stay stiffer without the fatigue that other materials have.

The airplane I built was called the Velocity-a 4 place canard design with a pusher prop. Mine had a top speed of just under 200 MPH. I made a couple of trips to New England from S. Florida in about 7 hr flight time vs. 23 hr by car! - 5 years to complete the project!!!

I can tell you must be a real hot rodder! I
