Re: Pros and cons of steel sailboats

I love climbing off a plane in a place where they speak a different language.

Kim says he can sail for a week without recharging the batteries. He had the batteries in his garage and decided he might as well use them.

Re: Pros and cons of steel sailboats

Just saw it on a restaurant TV near the end of 3rd, 36-0.

Total walkover. Why can't Colorado play in the cold?

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: Pros and cons of steel sailboats

Metal boats are designed to the metals fatigue strength which is considerably lower than the metals ultimate strength. That gives a huge factor of safety for the odd encounter with the things you really don't want to encounter I think that's real insurance.

Like this whale collision with a difference off Cape Town from memory. Any of the lightweight composite would have had their hulls seriously 'compromised' by a lively whale broaching right onto the boat. It dismasted this steel sailboat but didn't effect the hull and they made it back to the marina.

Yet another sailboat hit beam on by a ship posted here: Pros and cons of steel boats

Although it's a pretty rare event it speaks volumes about the real benefit of steel (and alloy) which is the reserve strength of metal boats.
With Aluminium alloy hulls you can have both lightweight and a large reserve strength.

When I said the same thing on BD.net, I was called a liar. No one else claimed it to be accurate .
No you weren't called a liar, you always liken being corrected to being called a liar. You didn't understand the nature of stability and seems fro your posts on this thread that you still don't.

Interestingly it's a common complaint from owners of your design that they are very tender, can't stand up to much sail and have to reef early. Any performance ULDB foam core composite 36 footer will be considerably more 'powerful' ie stand up to it's sail better.

Have you performed an inclining test yet on any of your designs? Aren't you itching to know where the real centre of Gravity is so you can give your customers an accurate stability estimate? maybe even a Dellenbaugh angle ?

I like the Dellenbaugh angle, it speaks volumes.

Re: Pros and cons of steel sailboats

The depreciation of fe boats has been commented on earlier in this thread. Given Brent reports of time and money spent have been questioned have kept an eye out for other information. In this months bws an waterline is asking mid 300s.given new they are around 1m.one wonders if the lost is so severe across the board for metal boats including aluminium.
