Correct me if I'm wrong, but wouldn't a design like this with a very small water plane area and heavy ballasted keel move very violently in rough...
I have been reading over these threads largely for amusement, and the question i keep coming back to is why the hell do you want to do this? As...
The box section is a very interesting idea... Basically making an I beam like structure from carbon. But am I understanding correctly that steel...
Thank you for the detailed explaination...very helpful
Thank you that answers my question nicely! Ive read that chopped strand mat improves bonding between glass layers, would that also be true if the...
You're over complicating this question I'm speaking hypothetically. In a simple panel lets say a rectangular board 4" thick is there a benefit to...
What would happen if a third skin were used on a sandwich laminate, in the centre? Essentially dividing the laminate into two cores. Would this...
Thank you for the response, the keel fin is ~2" at it's max width. Unidirectional is simply the fabric type i have chosen at the moment. The exact...
I have to agree with PAR, I don't really understand your design. To get the best stability and speed from the constraints, maximize LOA at the...
Hello, I am planning to build a keel fin for my sailboat project using seven layers of 1/4 and 1/8 " corecell foam laminated together. This...
Why even build the thing out of wood? It would seem to me that it could be done much cheaper and lighter if done entirely out of glass? I would...
Sorry for the lack of detail, its a 4' long lead bulb at the base of a fin keel. I'm specifically intersted in how to deal with the induced...
How does one calculate induced drag from a bulb?
Basically I am trying to estimate the frictional drag from the wetted surface on my boat, moving forward through water. Using this drag...
What are the common drag coefficients used for calculating drag from wetted surface?
That's a very interesting idea how would you remove the mast from the foam pipe? or would it remain in the mast?
That was actually my follow up question, this is still in a conceptual phase so I am yet to do that. What formula would you recommend for...
Any ideas on the feasibility of building a composite mast with a solid core to simplify construction? I've been considering building a 35' mast...
