Steel boats are usually a lot lighter than Wetsnails
, and many more traditional fibreglass boats. Few fully loaded offshore cruising boats are anywhere near their waterlines, anyway.
I have built about three dozen of them, and wouldn't consider going to sea in anything but a metal boat. One of the things which as made metal boats so expensive is the grossly outdated , imitation wooden boat building methods used to build most of them.
I have reduced the time it takes to build a 36 foot hull and deck, from Colvin's estimated 1,000 hours to under 100 hours, using origami boat building methods ( and I've written a book on the subject).
I have pulled together a 36 foot hull in two days.
My own 31 footer was launched a month after the steel arrived.
I once built a 36 in Winnipeg . In the three weeks I was there, I built the hull, decks, cabin, cockpit, wheelhouse, keels, rudder, skeg, engine mounts, tanks , handrails, hatches ,mooring bits , cleats, bow roller , mast fully detailed, solid lifelines, in effect all the steel work . The owner had hired a welder to weld on my time off , so by the time I had left, most of the metalwork was done.
When the metal work is done, you are much further along than you would ever be with a fibreglass hull and decks.
A friend, who has owned many fibreglass boats, tells me that there is far more work chasing down deck leaks on a fibreglass boat, than in maintaining a steel boat, which has most of the deck hardware welded down.
Welded down stainless deck hardware never moves or works loose. They don't leak.
Having single handed across the Pacific 9 times , given the things I have collided with in the middle of the night , I don't think I would still be here, had I been in a fibreglass boat.
In Jimmy Cornell's book "Modern Ocean Cruising" he interviews ten circumnavigators , 8 of whom said they would prefer a metal boat next time, and several who had already started their metal boats .
There is a huge mass of debris floating across the Pacific from the Japanese earthquake and tsunami. I wouldn't want to be out there in a non metal boat.
My current steel boat , built in 1984, was painted with 30 gallons of epoxy tar. My annual maintenance is around 1 or 2 hours a year, and costs under $50 a year. She has never been sandblasted, and has only been hauled out twice, in Tonga in 2000 and 2003.
As it is mainly outside corners which have problems with paint chipping, I have found that trimming all outside corners with stainless can reduce maintenance by up to 80%
Some complain about the cost of fitting out. I have dealt with this in my book. I give instructions to build a 540 GPD watermaker for under $1,000. Some say headsail furlers are expensive, so I have designed one which can be easily built for under $200. The sheet blocks in my book cost around $2 each and take about 20 minutes or less to build. The composting head , costing about $1200 to buy, can be built for under $50 . Ditto the Lavac type head. The engine driven welder costs under $50 to build. The windvane self steering, under $25. Anchor winch , under $50, bilge pump, under $20, etc etc.
I new Zealand a designer named Birsell designs a simple hard chine steel boat based on the " Deerfoot "concept. Most of their owners are enthusiastic about their boats .
Aluminium is a great material for cabins and wheelhouses, above the waterline, but corrosion problems, and problems getting a non corrosive antifouling would make me leery about aluminium hulls. They are also far more expensive, and aluminium welds are nowhere near as reliable as steel welds.
