Pedro 950 made of Corten steel?

[tony_lavelle]

I've bought a 1984 Pedro 950 that was kept in immaculate condition by the previous owner. There's not a speck of rust and you could eat your dinner off the bilge, it's so spotless.

As I understand that the best Dutch boats are/were built of Corten steel, can anyone tell me if this was used by Pedro? Sadly there doesn't seem to be an owners' association.

I thought the whole point of cor-ten was that it rusted to create a protective layer. With this in mind, if your boat was made of cor-ten, wouldn't it be the opposite of 'not a speck of rust'?

Yes - Cor-ten Steel is a steel type that forms a protective layer of oxidised material (rust). That layer prevents weakening of the steel as normally happens with rust. Effectively the rust acts like paint does for normal steel.

It’s popular with architects who want to create a weathered look.

I think it’s incredibly unlikely anyone would use Cor-ten in boat building.

The lack of rust is probably due to very good preparation and painting.

This thread caught my eye as we are working on a project that uses Cor-ten (or weathering) steel in a bridge.
Having wondered about the use of this material in boats I found it easy to find examples made of Cor-ten steel....like this one.

I guessing this boat used it exclusively

The 188' Midnight Saga/S-Cape was built in the late 70's with Corten steel.

The crew did quite a lot of chipping on the hull to keep on top of the corrosion, but as said mostly surface stuff.

In the early 70s ,I was moored off a boat yard in Auckland. The foreman said they tried Corten, and found it had no advantages, but many disadvantages. It warped more, was far more expensive ,and welds, round , flat bar or angles couldn't be found in corten, all of which sacrificed itself to the corten. They went back to common mild steel, happily .
Yes, it was probably the proper paint job which is responsible for the boat being in such good shape, not the corten.

Boats were made of Corten steels and the problems were mainly around the welds, they suffered terribly and parts literally fell apart either side of the welds themselves.
