The above paper by Savitsky includes photos of the flow of water under a V hull using both dye and tufts. Both show the flow is essentially...
A small heavy sailboat will pitch a lot. To make it pitch less, concentrate the weight in the middle, and make it lighter with balanced ends. A...
Well put, Tom.
FF, I bet you are correct.
Tad, after more reading, I concur with you.
Sottorf, great paper! Here is a gem in there near the end that I'd read before in another much older paper. Edited for brevity: "The sharpness of...
After reading a bit, maybe these do have merit!
What market? Can anyone point out a paper that documents experiments on Sea Sled designs, to get some data rather than the self serving hype of...
FF, the trailering laws across this great country of ours are rather, um, poorly written and inconsistent. A couple of years ago, when I started...
Malabar XV !?!?! That should be in a fine museum, not chopped up for salvage!
Tad, your Yellow Cedar has come up here and other threads before. It looks very attractive. I like a lot about it, but I've got a couple of...
Looks fun!
Tunnels, I used to also think this same way about strakes, but some research showed the error in this concept. The reason strakes are useless...
Tom, makes sense for a shape to achieve constant deceleration. The outer flare continues to impart the same deceleration even as the vertical...
I agree, Easy. I think the lift forward added by the strakes in the Muller study is due to this spanwise flow: its a displacement hull form that...
All very good points, Thanks. Regarding (1), I totally agree. I'm using this as an excuse to really act like a real NA and do the math, as well...
The peak BSFC precisely coincides with peak torque. I agree, Tom, that long and light often does not correspond to the typical packaging...
Oyvind, I think the right solution is the one you did, not the one you recommend: remove the notch, make the bottom shape continue to the transom....
