You may be putting the cart before the horse
I have owned 2 classic LandRovers and know where you are coming from. The aluminum sidings never rusted although I can't remember ever washing my car. Also, the chassis was overbuilt so heavily (and the capsize ratio so low) as to give a very safe feeling in traffic as well as terrain. At the same time, however, I never misled myself into believing that these heavy cars were necessarily safe in all conditions. First of all, the passenger cage was not constructed strong enough to survive several types of rollover. Secondly, the wheel suspension was very oldfashioned and not tracking as well as even the simplest Toyota. Also, my aversion to maintenance was primarily cosmetic, I made sure that brakes, tires, drive train, lubrication and so on were carefully maintained.With boats it is more or less the same deal. If you buy a Colin-Archer pedigreed heavy vessel such as a Westsail, Ingrid, CT40 or Hans Christian, the hull is likely to survive most of us by several decades. However, without painstaking attention to standing and running rigging, winches, steering, navigational equipment and safety systems, to name just a few, both the boat and you are likely to come to grief pretty fast. In short: you will always have to take care of her. It's never the other way around. A heavy vessel will not take care of you. In fact, along with many crabs along the way, it might one day crush your hand, foot or worse.To become a sailor who knows how to take care of his vessel, rather than become afraid of her, you will need to put many miles under your keel. Unfortunately, this is exactly where the rub is. Heavily built vessels do not sail well in light or moderate winds and most are consequently sitting in harbors all over the world, waiting for that one great weather window that will allow them to make the next crossing or passage. If you don't believe me, just drive South till you get to Puerto Vallarta or Mazatlan and talk to the wives of the skippers of the great-looking heavy vessels there. Many will admit to you that the skipper was planning to circumnavigate the Pacific or the globe and that they left San Diego 1 or 2 years ago......This is not to say that heavy vessels are poor sailers. I have been put to shame by crabcrushers with experienced skippers time and again. As long as the wind is in the upper teens and above and the course is not too sharp on the wind some of these great-looking lassies can wiggle their sterns at many a lighter vessel. However, the skipper will have to slap on a whole lot of canvas and - believe me - sailing a heavy vessel at 25-30 degrees heel in a gale is no job for beginning or fainthearted sailors. The story is quite different, however, when it is necessary to sail against the Trades. That's why most of these ladies have big auxiliary engines.The long and the short is; unless you do have a lifetime to teach yourself how to sail a heavy vessel properly (and finally get to have real fun doing it) you are probably better off to first learn the finer points of ocean sailing on a lighter built vessel. Now, if you would be able to spend well over half a million US $ on purchasing your vessel you could have your cake AND eat it by buying a vessel constructed with plenty of weightsaving superstrong hi-tech materials. This gives you the equivalent of a Bradley fighting vehicle instead of a WWII Sherman tank.....Have fun,Flying Dutchman
