One thing about aluminum and steel boats, is that plate can be bent around one axis, it can be bent around another axis, but not both at the same time. Well it can, but it takes a hell of a lot of heat or force to do it. Very hard to make pleasant curves. With plate, you end up with slab sides and hard chines. To do curves, plate must be formed or contour cut and welded in thinner strips.

That's why lots of steel and al boats are a bit ugly. To make them pretty is not easy.

But then beauty is in the eye of the beholder. I've known people who have fallen in love with one, only to turn away when they discovered it was steel.

Smooth round bilges in 1/4" thick plate are perfectly possible. It requires a degree of skill which is not very common now days. But it can be done.
Without heat and without cutting the plate in numerous tiny pieces.
I hope the picture comes out.

Ski- Florence was designed and built by George Sutton, launched in 1964. I think she was probably one of the last of his boats built in New Port Beach California as he moved to Tarpon Springs Florida in 1965. She was custom finished for Jay Stoddard the then mayor of New Port Beach.
I think that the boat was built very much like a wood boat from a table of offsets (which I have) her frames built and stringers run then plated. Each piece would be tack welded and then bent into place with wedges and come alongs. It is possible that a large english wheel could be used to shape plate but I have not heard of anyone doing a steel boat that way.
Smooth curves are a matter of practice and taking your time. George Sutton grew up in Portland Oregon building steel boats with is father and brother. After the death of his brother in a welding accident George moved to New Port Beach and built steel boats there for a number of years. In 1965 he moved to Tarpon Springs and built boats there until his death in ( I think) 1988.
Pictures are of the book on Florence A and the yellow sheet is the hand written table of offsets.

Well done indeed. But the only way to get a compound curve is either to heat or beat, come alongs won't do it. Rosebuds and hammers will!!!

The numbers of large steel yachts with curves galore is significant. A dock walk in a large yacht marina or page turning in a high end yachting magazine reveals plenty of steel yachts. But alas, few are Fe below say 120 feet. One of the exceptions is a steel plate vessel called Sonata, built in a smart fellows back yard in CA and cruised extensively in the PNW. It is a Bruce Roberts design and a look around will show many of these gorgeous vessels including a TF member.

I've a few friends with Buehler design steel vessels that are quite nice looking. Broward's Al yachts are curvaceous as well, both inside and out. Coastal Craft makes curvaceous Al vessels that many have thought to be FRP upon first sighting.

The models and makers of beautiful Al sport fishing boats in the PNW are too numerous to name. For many years several NZ yards have specialized in Al yachts,think Jeffrey Archer designs.

Of course how many Tuckers or Jaguars have you seen that are FRP. Look around, metal abounds.

I find Coastal Craft most interesting as to an aluminum mid sized cruiser. I have tremendous respect for the designer, Greg Marshall. He's a Bill Garden Protege who has done a lot of work for Westport, has done some beautiful newer designs for Burger, which unfortunately they've never sold any of.

Coastal Craft's 40' has a top speed of 37 knots and gets 1 nmpg at it's cruise speed of 30 knots. At 7.5 knots it gets about 3 nmpg. Their 56' even cruises at 27-30 knots and has one of the most incredible flybridges I've seen. Then their 65' has won several awards, and rivals any boat in it's class styling wise. All their boats do use IPS. We were very tempted by their 65.

Here is the 40'.

Ulysses is 52' or so, hull steel with Al house and I do not think there is a square spot on her. If you can frame it you can plate it. Detroit found that out over a hundred years ago, thus a new model every year with a slightly different flare or bend. And if Al did not bend readily they would make cans out of something else. Of course there is an art and craftsmanship involved in any construction medium. You will note that there are many square and chunky glass boats too probably for the same reasons costs and talent.

I thought the background looked familiar. Hope you can keep the sawdust out of any painting you be doing and your repairs go well. Maybe we will see each other on the Columbia when you are back in PDX?

The Dutch yacht builders sure seem to make rounded surfaces in steel and perhaps even with compound curves. I could not find a good picture of Klee Wycks bow but like FlorenceA she seems to have steel that curves horizontally in toward the fine entry and also vertically out from water line up. I think some of this is done by laying up strips of steel almost like planking but then faring to an art form.
Many of these boats built there under 100 feet and a search of steel hulls under 60 feet for sale will turn up many pages. It has been interesting to me to see so few steel pleasure boats here in the PNW and so many there with climate and cruising grounds not that different.
There is currently a Ukrainian built 50 foot steel hull for sale that I think is stunningly beautiful. I wish I could get her out of my head.
