I don't understand why you wouldn't rotate the whole assembly from the end of the boom instead of from the base of the mast. You've already got...
Oh, so you're copying something you own a copy of. Do you also own the right to make copies of this material and sell those copies? It's called a...
You can use the heeling moment of the boat to estimate the force on the sail. As indicated earlier, heeling moment at 30 degrees is pretty normal....
First of all, you're reefing too late ;) Second of all, there's no reason you can't rig the new lines first, and the unrig the old ones, or douse...
1 gallon of water weighs 8 pounds. Half a gallon of water weighs, therefore, 4 pounds. Guess how much volume a half gallon bottle displaces?
This is almost certainly a scam.
I think it's around 40 feet long, and I don't think it's an Atkins. Atkins drawings tend to be different in a couple of ways, and the fully...
Do you know what the righting moments of these boats are, roughly? With that, you can estimate the maximum force that will be applied to the...
I hopped on boats.com, and clicked on the 'Advanced Search' link. This gives you a great big form you can fill out. Click on the "Power" and...
That was kind of snotty, maybe. Sorry. Anyways, let me qualify my 'rules of thumb' with this: 8% as a starting point, actual values people use...
I think I did say "rough" measure, didn't I? Yes, yes, there it is. I see it. Interestingly, if you take your 18.5 M^2 keel as 8 percent of the...
Ivor, are you asking: Given a drawing or other specification for a keel, how does one determine its area? (this is geometry, and you're primarily...
TP52's are awful IRC racers. They are terrific as a sort-of-like one-design class, although that seems to be basically an arms race.
Look for a copy of '20 Small Sailboats to Take You Anywhere' by John Vigor. It explicitly includes boats that are NOT really "blue water cruisers"...
