WHAT!! I agree with Kraken, a propeller can't have an horse power rating because it slips, It can probably have an IHP. Andrew

Hi folks, Now I've got jist of things on the Forum and seeing how the chat goes, I thought I'd pop this link in for those interested picasaweb.google.com/fmcdove It's photographic record of the restoration of N.B. Dove formally Britania, the Birmingham water bus. Andrew

By using Stainless you can reduce the thickness to reduce cost and still maintain strength. However you would have to make few design changes to the standard narrow boat, due to the shrinkage and distortion created when welded. There is another material, Yarwoods called it "Coppered Iron" now known as "Core 10" I used this on 20' x 10' supply boat. the plate was 3mm thick but very strong due to the shape. Andrew

Sorry I missed this "off topic" I don't know what the bottom is made of, could be a bit Red Diamond Caggy had laid about, but it's been welded with Stainlees rods ??? dam good job though. Andrew

Arthur, hello again too, you will find that the early Sea Otters were of a 6, 6, 4, build. However I did make the ballast tank with a "v" bottom for strength. This was to make them as light as possible but strong enough for trailing. I had quite an rate of failure when folding the side sheets for the gunwales and roof, so there is quite bit stress built in. I don't know what the longer ones are made off, I'm not involed now.

Eveyone to his own, I afraid I don't do wood, well not very good. GRP.... never had a bash. Prefer Iron personally Andrew

I agree, if you black it often and moor next to a Sea Otter, it will last for years. And you can DIY repair it Andrew

Work hardening can lead to cracking like with our copper steam pipes, they have to be anealed every so often. every time you have contact with another boat or lock the plate is flexed. If you want to how much a boat flexes in locks, stand on the back of Dove, you'll be supprised Andrew

From my experience working with Aluminium boats, you can only bend rolled plate one way, it has a grain structure and also work hardens. with the boats flexing in the water and more so in locks this could lead to proplems. A good example was the fast ferry to Ireland, they had full time welders on the car deck welding patches over stress points. Andrew
