Eric, If we have two boats of close designs, i.e. same displacement, Lwl, and similar hull shape, there primary difference is the Cp values, then...
Texas is a fairly big place. Any idea what part of texas he lives in?
It looks like you want ease of construction. The stability of such a round bottom would probably be a problem. Add one chine on each side and...
James, I did a quick google search and found that most used Deck Barges were around $100k to $200k, the lowest one I saw was $50k Here are a...
Top Speer (tspeer) gives an equation for the sectional areas curve, which includes Cp, in his paper: http://www.basiliscus.com/CSYSpaper.pdf...
Leo, You are amazing! The draft is very useful. Thank you. ~ Michael
1 m/sec = 1.9438 Knots g = 9.8 m/s^2 = 32.174 ft/s^2 V = ( g / (2 PI ) )^0.5 x L^0.5 Factor = (( 9.8 m/s^2 ) / ( 2 PI) )^0.5 x 1.9438...
Soren, Yes thanks for your help. Eric Sponberg also just explained to me in another thread that SAC is not really used much in designing...
Eric, thanks! Yes that helps clearify a few things. I have a fair graps on design parameters for displacement mode and the steps toward...
Eric, this question may be jumping a bit ahead, so if you want to wait to address it I understand. But, it is related to wave form resistance....
Are you working with Gel coat, polyester or ? I once used "Pam", the food product, for a epoxy layup. As I remember Pam is (or has) a silicon...
Yes, I think the concept could be migrated into a reasonable trimaran design. The trimaran audience is fairly open to experimental deisgns. There...
On further reflection …. The foil curves represent some of what we have learned about 2-dimensional models of fluid dynamics. These 2-D models...
modern Sectional Areas Curve The Sears-Haak curve seems to be very similar to Skene's Sine/Trochoidal. Which curves do you use for SAC's...
What about adapting to a trimaran?
Thank you all for your response. Soren I gave the expected Cp to indicate the Froude Number or Speed/Length ratio regime that I am concerned...
I am designing a sailing dingy which will fit on the bow of my 37’ sailboat, so there are a number of constraints on the design. The Lwl is about...
Wedge hull I played with some wedge shaped hulls just as an exercise. See pic below. 12 degrees transverse is supposed to be minimum...
Kites Are you considering a spinnaker or a kitesail such as at kiteship.com ? What have you seen? I'm very interested in kite-sails myself....
Yes, thanks again Eric, very nice.
