Don't suppose you could post pic's of the boats.. lot more to hull type than material and condition...
Round hull, Multi Chine, Single Chine like the Van de Stadt Dogger 31 I took from Perth to Port Huon, Tasmania..
They all perform differently..
Oh.. and Corten is better..

Not so. If welded and painted and/or with less than perfect drainage, Corten steel sucks.

Re: hull type

Depends on what you're using it for. For example, shipping containers are made using Corten and they will last for quite a while.

Re: Hull Type

I have a 1981 30' cedar strip/glass/epoxy sloop, and it's been a good, strong, and attractive boat.

The thing about these cold molded boats is that their condition is totally dependent on your ability to keep water out of the wood. If your fiberglass layer is punctured under the waterline or if there are any areas of exposed end-grain (as occurred in our boat at the top of the bow stem in the anchor locker), water will find a way in, but it won't find a way out (especially if it's glassed both inside and out). This can lead to serious rot issues and compromise the integrity of the hull if not caught in time to dry out the wood and reseal the glass.

The good news is that these hulls are light, strong, and endlessly repairable if you get to know wood and fiberglass. The bad news is that these boats are sometimes referred to as "the bastard child of the boat market" because every construction is unique and these hybrid construction techniques are not widely understood by normal buyers, at least in the US. That said, I really love our cold molded boat, and our surveyor said he wouldn't be surprised to see the hull last another 30 years or more if treated right.

Re: Hull Type

You'll get argument from the steelies whether Corten is worth it or not. I've read and researched this online in the past e.g. DIY boatbuiding with steel.

Yes, no, maybe. It depends on the boat design.
