Like I said, ~14x more than aluminum. I'm guessing that you'd also want to do more than 0.125" thick hulls..
Last time I talked to the Pardys, they were talking about a copper nickle boat , zero antifouling or maintenance needed. I suggested he first ask Winston what his maintenance costs in time and money per year are, then calculate how many dollars and years it would take to make up for the tiny amount of maintenance time and cost per year going for steel would work out to.
Several copper nickle boats were built in Britain. Expensive but doable. I once sold a set of 36 plans to a guy in Malasia who was planning to build in copper nickle. Don't know if he ever did.

Wrong! Steel sinks much slower, because the same impact would create a much smaller hole, if any hole. It would probably just dent from an impact which would tear the bottom out of any non metal hull.
For this reason ,wood sinks the fastest, unless it is a raft.

Re: Pros and cons of steel sailboats

Tomorrow Kim and I are going out for a photo shoot on FRANCIS. The German magazine YACHT is doing a multiple page feature story on the boat and we need some new photos it seems. So I'm happy that I will enjoy a nice day of very fast and easy sailing on one of my beautiful creations.


I suppose I could say defensive and cranky things but I'll let my work speak for itself.

Shape of plate be developed at factory with hydraulics so no limitations and complex curves permissible. Heard of molded Al. Why not molded steel.
I was moored for a year off a shipyard in Auckland which built tugs ( A&G Price Limited) They said they had tried Corten . Wasn't worth the extra cost. You could only get it in plate, not in angle, rounds pipe etc, so any mild steel welded to it got ate by electrolysis, as did the welds, which couldn't be got in corten. It was far more prone to distortion,and more expensive. The foreman in that yard was building himself a 36 footer, and had no use for corten. He said common mild steel was as good as anything.

A Dutchman told me of a company in Holland who had matched dies made for a round bilged steel hull. Each half was pressed out of a single sheet and joined along the centreline. Super fair ,but super expensive.

Yeah, despite Brent's yelling and screaming to try to cover it up - his works speaks for itself. And it doesn't really say good things.

ok i am going to stop now
Actually, I think that's a good summation. If being safe in a steel submarine in the Arctic is very important to you - Brent's boats are pretty good for that.

I don't think anyone around here would argue that point.

Re: Pros and cons of steel sailboats

I said a similar thing about 4000 posts back - If I was possessed enough to want to sail the North West Passage, a Brentboat would be high on my list.

If one is looking for a utilitarian boat with the ultimate survival aspects as the main goal, his boats are at or near the top and I don't think anyone here has ever disputed that.

It is the messianic zeal that says any other kind of boat is basically stupid, no matter the purpose it is for, that has caused much or most of the friction on this thread.

The same logic applied to cars would be a diesel powered early Land Rover.

Neither of them suit me and my needs.

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

Jon:
4,000 posts back?
I read he first BS post tonight and I thought, "Shitski, it's like a broken record around here. Nothing ever changes with Brent." Well, I have a couple of new things in the work that will have you chatting and arguing, in a good way, and I'll spring them on you when the time is right.

Tonight I am sitting here excited that tomorrow I will experience performance under sail that truly raises the bar. And, I'm taking my granddaughter out for a put-put around the marina before we go sailing. Dad, Max, has to stay with her and Dad has to stay close to home because my grandson is due any day. I am doing my best to insure the strength of the gene pool. The pleasure has been mine.

Re: Pros and cons of steel sailboats

Are you due for a decent breeze tomorrow?

Is a chute going up?

Take a laptop and keep us posted in real time - I'm going to be home with my brand new today grandson and family so I'll be able to stay on top of anything you might post.

Or not.
