Deering, since mathematically modeling these two designs would be quite a task, I think it would be not too difficult to build two or three...
There was a discussion on another forum about rolling chocks for power boats, and this "staggered" design was brought up, as opposed to a...
Thanks Lepke. My mate hasn't performed an engine survey yet, but I would assume that it was well-maintained since it was a government vessel all...
Does anyone have any knowledge of these Japanese medium speed engines? Any opinion if 23,000 hours (assume properly maintained) would be the...
masrapido is correct. Remember basic physics, 750W equals one hp. That motor would barely be adequate as a trolling motor for a canoe.
Reuben, those are good words of wisdom. So when you say “backing coat” do you mean the first couple of layers of glass use VE resin, then the...
To clarify, what I'm wondering is if the gelcoat itself offers enough protection? So a vinyl ester gelcoat with "normal" polyester resins in the...
For a new construction fiberglass boat, trying to watch budget, would it be sufficient for long term blister protection to rely on an upgraded...
I recall that Bob Beebe made a similar comment that slavishly copying a fishing boat design does not result in an efficient personal cruiser. But...
So it would seem that my boat is the Turkish version of a Novi :) with an 18' beam on a 45' waterline. Luckily it has a good displacement at 42...
Wow that Eyemouth is funky looking. Very functional, but not exactly a stylish yacht! I've returned from Istanbul. The final dimensions of the...
On a different note, I notice that neither Gerr nor Wyman powering formulas take into account beam. Obviously a boat with a L/B ratio of 2.6...
I've always understood that very wide beam boats would always have a lower ultimate stability because of their higher initial/form stability. If I...
So this very wide design has a capsize angle of 72 degrees, versus the 80 degrees of your 1380 boat, versus 90 degrees for Diesel Ducks or...
I have received the stability curves (hydrostatic and GZ) for this vessel, in preparation for my trip there in two days. I would greatly...
I suppose I was unclear, but this is the designer who I am in contact with. His company is invested in several shipyards. So it’s a design-build...
fallguy and AdHoc I hear your comments about hiring a third party to check the design. I very well may if I decide to move forward with this...
Good morning. Allow me to clarify... I'm not a rich oil sheik but just a normal working stiff :). Adapting the commercial trawler design for...
Certainly it is less efficient to push. But my required operational speed is 8.0 knots.
