Re: Pros and cons of steel sailboats

I pulled the trigger and traded for the vessel. Anxious to spend some time down in Malaysia in the coming months. I am exploring the possibility of forming a fractional partnership with two other individuals to share use of the vessel along with the lifetime membership in one of, if not the finest, 5 star resort golf course & marinas in the South China Sea. Any experience with that sort of arrangement?

Yet some of the above claims have been refuted over and over in this thread - as an example the so called T-boning incident. And many of the brentboats have had framing added to give them more strength - seems their owners didn't think that they were strong enough. Looks like your guesstimates weren't good enough for them.

Fiberglass boats have done the NW passage, and made thousands of ocean voyages with no incident. What I cannot figure out is why do brentboat owners run their boats into reefs, etc so often? If you compare the number of brentboats to the number of collisions, groundings, etc, it seems like there is a real problem with them.

Which has nothing to do with your lack of knowledge of the structural properties of materials or structural design.

Just because someone did a hack job at guessing the stability of a brentboat doesn't mean that you have the ability to do a real stability calculation (and understand what you are doing).


I was going through a boatyard today, when someone I was with mentioned to me that a nearby steel sailboat had been recently surveyed - the surveyor put his finger through the hull where it had rusted through.

Re: Pros and cons of steel sailboats

First let me say waves are not measured in feet and inches, but in increments of fear. Mr. Swain has never paddled out in 12' surf and never will. A twelve foot wave breaking on coral typically would have a 20'-24' face. His contention that one of his little boats withstood 16 days getting pounded before being successfully dragged across the reef back out to sea through these same breaking waves is not the testimony of a sane individual.

Re: Pros and cons of steel sailboats

Brent:
Frank is strip planked and glued. Fasteners were used to hold the strips in place for gluing. The everything inside and out was covered in a layer of protective GRP for abrasion. Deck is grp skins over foam core. The interior is all cored panels. Keel floor structure is welded steel. In the end I think you'd have to call it "composite" construction ranging from red cedar to carbon fibre. Of course, by your rules, you have ZERO experience in this style of construction so you cannot possibly have anything of value to say about it. So don't bother wasting our time with your comments. Play by your own rules.

Did you ever get any definitive stability data on the boat?

I hope you give us a report after you sail the boat.

Re: Pros and cons of steel sailboats

Bob, Checked out your site and your little house design and thought you might be interested in the little house I am building on one of my favorite spots in the rainforest overlooking a waterfall on a farm I own in Costa Rica. About halfway completed and quite the challenge as you can imagine.

Yes, my experience too, exactly.
