Right now my design is at 6' draft for my boat, but I've stretched her and increased her sails, which makes me want to increase her draft. But I...
I'm reading Dave Gerr's Propeller Handbook and playing around with the formulas. When I combined the formula to estimate the maximum theoretical...
I was watching this TV program (on the science channel I think) where they had gained some serious increase in efficiency for an enormous tanker...
My dog Sammie, the greatest beagle ever, just passed away yesterday so I'm pretty sad over it; but it was time. I'm trying to get my mind on other...
The maintainable lead-acid batteries provide the longest life (over the SLA) and are the most efficient cost effective solution. They're great...
I was reading this article: GM Reveals Nano Magnesium-Titanium Solid Solution Alloys for Hard, Strong Corrosion Resistant Coatings It...
I'm curious, has the logarithmic spiral been used to gradually increase leverage as the rudder angles further and further port or starboard?...
I've read most every thread that I can find on window materials and they discussed pros and cons of the basic materials, but none of them spoke of...
I've been reading about partial skeg (also called semi-spade) rudders; they are supposed to provide some of the efficiency of a full spade rudder...
Rudders accomplish their work using friction, so why not harness the lost energy and generate some power with it. All day long we must allow a...
I want to take the time here to thank everyone for all the smart information that I do find and for the very knowledgeable suggestions that I've...
I've read about pitotable ballast systems and found them to be very interesting; but the systems that I've seen were complex and required...
I was talking to some family members about my thoughts on building a boat and one joked that they didn't see a self leveling bed on my plans. We...
