These are actual experiences, not abstract calculations, which have far less relevance, unless you are ready to tell NASA that they are wasting their time on testing gear to destruction, as you can give them far more accurate calculations than reality, on your computer. Perhaps you can save Ralph Nader a lot of product testing expenses, by telling him that he need only read the price tag on any item to find how good it is, or simply double the price on anything, to double the quality automatically.
One need only cruise the BC coast to find many of my boats cruising, and willing to tell you what they have expereinced in cruising them. Best get your advice on any boat, from those using them, not from those who have rarely, if ever, seen one.You dont have to cruise far to find one. What they have to say is far more valid than your armchair calculations, unless you consider anyone who disagrees with foregone, armchair conclusions, based on zero expereince in the boat being discused , to all be liars.
I dont need calculations to know that a 4 inch sch 40 stailnless pipe welded in to the deck, and a plate ten inches below it ,welded to the hull is stronger than a bolted down pot metal cleat.I dont need any calculations to know that a half inch stainless rod chock, fully welded into the steel bulwark is stronger than a bolted down "yachtie" chock on a teak rail. I donty need calculations to know that a 34 inch high, solid stainless sch 40 pipe rail is safer than knee high ""yachtie" plastic coated rails, the stanchions made out of something slightly thicker than stainless tinfoil. I don't need calculations to realise that an on epiece aluminium hatch is more waterproof, easier to use, and and tougher than a decorative teak sliding hatch and dropboards, a hairbrained arrangement. I dont need calculations to know that hands on building and cruising experience over 40 years produces a far better and more practical boat than calculatuions made by the best comnpruter whiz with minimal if any low budget ocean cruising expereince, off the beaten path. I dont need calculations to look at a 2x4 alongside a 4x4 and figure out which is the strongest.I dont need calculations to se that 3/16th aluminium block cheeks are stronger than plastic ones.I dont need calculations to see that the parts which make up a $30 block can be easily made in minutes ,out of less than $2 worth of material. Computers are no substitute for logic, and comon sense. abandoning the later and relying too much on the former, makes for many screwups.
Lack of logic has made many boats excessively expensive ,complicated and impractical for cruisers.
Ah! Another classic Swain-ism. Glad to see that you are still approaching these discussions by trying to avoid the key points and using hyperbole to change the topic rather than address the comments with a well reasoned and meaningful response. Nice try Brent.
No one said that a steel boat or its hardware cannot be strong, that its details are of questionable strength, or for that matter that a steel boat isn't stronger than a typical production coastal cruiser. And no one said that there is no one out there who enjoys owning a steel boat.
What was said, and shown in simple calculations over a decade of discussing this with you, is that pound for pound, there are other materials, which produce a much stronger boat, and that these materials may also be cheaper when taken as a whole, and which also may produce a finished boat in fewer hours than building in steel.
Go back and look at the spread sheets that I posted in our early discussions. These calculations are not theoretical and unproven. We are not talking about complex load path calculations; merely simple strength of material calcs. These are simple, time proven, highly accurate and validated calculations using formulas of a type which have existed for over a century, and which have been easily validated in the laboratory and in real life for as long as they existed.
Have a nice day,
