Re: Pros and cons of steel sailboats
I just read the maintenance story about the Roger Henry,. When he mentioned water siting on stringers, it was obvious that she didn't have sprayfoam insulation. Water just runs over it . Steel behind it stays dry. Doesn't sound like he had any sprayfoam at all in her. He mentions using a woven insulation, which would be waterlogged, and sopping wet full time in colder climes . Tried that once ,then pulled it out and sprayfoamed it. Did he have insulation that absorbent all along, ( which would inevitably cause sever rusting under it)? Doesn't sound like there was much paint inside at all ,from the outset. Thick epoxy over wheelabraded and zinc primed steel , with spray foam insulation, would have no such problems .
He mentioned having to take out thru hulls to sandblast . Welded in stainless pipe nipples would have no such problems , nor any problems.
He also mentioned a wooden bulwark, which is a huge mistake on any steel boat. Just running the topsides plate a bit higher ,with a stainless pipe cap on it works much better . That is a vulnerable place for a piece of wood.
No boat building material or method is immune from such mistakes. Get it right at the outset ,and you wont have a problem,. Most of his problems could have been easily avoided in the building stage.
He did say"The difference between an amateur and professional is not in the results, but in time spent." or words to that effect.
He'd be wise to keep an eye out for good brentboat , and make the switch while that boat is still worth something.
