I like to diy very much. A lot of handmade things are very usefull in ordinary life. How to make different things? What craft of crafts should I choose? Constuction is anothe side of creativity. In this field you must be able to make insulation and padding, waterproofing and repair or reperation, fix and pluster ect. You have to know a bit about welding, installation or disassembly of different things.
METAL HAS BEEN USED to build ships for about 160 years, and very large metal yachts were being built as early as the late 19th century. In 1895, for example, Nat Herreshoff designed and constructed a radical 123-foot composite metal sloop, Defender, to defend the America's Cup. She was built of aluminum, bronze, and steel and within six years was so debilitated by galvanic corrosion she had to be broken up.
It wasn't until the 1960s (except for some boats built in Holland, where steel has long been a favored material) that metal was used to build sailboats of more moderate size. Bernard Moitessier, an early pioneer, commissioned the construction of his 40-foot steel ketch Joshua in 1961. By the middle of the decade, aluminum was also being used to build both racing and cruising boats. By the mid-1970s, aluminum was the favored construction material in America's Cup 12-meter boats (the first was Courageous, built in 1974) and remained so until the mid-1980s.
These days racing boats are rarely built of metal, though it is still very popular with certain cruising sailors. For those tired of chasing down deck leaks on wood or fiberglass boats, one big attraction of an all-metal boat is that it is very tight. The hull-deck joint is welded and all hardware such as cleats, genoa tracks, stanchion bases, etc., can be welded in place, with no fasteners penetrating the structure. Instead of leaks, however, one must worry about corrosion.
One big advantage of metal boats is that deck hardware can be welded rather than fastened in place. This cleat may be strong enough to lift the boat it is installed on and will never be the cause of a deck leak!
Pound for pound metal is far stronger than wood or fiberglass. Unlike wood and glass, which have most of their strength oriented along the lay of their grain or fibers, metal is equally strong in all directions. Metal is so tough one needn't worry about wasting strength because of this, and much trouble is saved because the material can be laid down any which way. In a wood or glass boat, by comparison, designers and builders must always take care to ensure that material is aligned along anticipated load paths.
The skin of a metal boat must be kept quite thin or the boat will be much too heavy. The thin skin, in turn, must be completely supported by a frame or it will flex too much. The traditional approach is transverse framing similar to that found in plank-on-frame boats. There is a backbone keel with a large number of transverse frames attached to it, plus thin lateral stringers to hold them together. The alternative is longitudinal framing, where fewer but much larger ring frames are joined together by a large number of stringers.
The advantage of transverse framing is that smaller, more closely spaced frames intrude less on the boat's interior than do bulkier ring frames.
