It has taken me a long time to
appreciate how small details like this make a big difference on yachts. Inches
of freeboard here, square feet of sail area there.
Another famous North American boat
designer, Ted Brewer, once told me he’d wished he’d given one of his designs an
inch more sheer at the bow. An inch? On a 40-footer? “It would have made a big
difference visually,” he assured me.
You probably know as well as I do
how a mainsail can start lifting right next to the mast when it’s backwinded by
the jib. There are days when it seems to do this on purpose. But it takes only
the smallest adjustments to put things right: you can ease the jib sheet an
inch, or sheet in the mainsail an inch, or tighten the clew outhaul an inch.
That’s all it takes to make the difference. Anything more heavy-handed marks
you as a neophyte.
I used to scoff at the notion that
an extra inch of beam could make a difference to a boat’s performance. After all, it was regarded as a minor miracle
if, in the olden days of wooden construction, a boat was finished within two or
three inches of her designed overall length.
But an inch of beam does in fact
make a difference because the interior volume gained through that inch
stretches the whole length of the boat.
It’s more in the middle and less at the ends, admittedly, but
neverthless it’s not just an inch across the belly section.
I used to sail on a old wooden boat
in San Diego that had an extra wooden skin added to the outside of the hull. It
was only about 3/4 inch thick, but over the 35-foot length of the boat, it must
have weighed a ton and I imagined the boat
must have sunk a good couple of inches in the water. But an old salt came on
board and asked the skipper: “How much extra freeboard did you gain?”
I forget now exactly how far she
rose out of the water when that extra skin was added, but it did give me
furiously to think about how much the extra volume of water displaced all
around the hull must have weighed, and, in consequence, made her float higher.
I have more respect now, when people
tell me about small changes that have made big differences. I don’t scoff any more. If Chuck Paine says square edges are faster
than round edges I’m happy to accept it. I wish he’d give me advance warning of
when he’s going to appear in my dreams, though. I’m sure I could think of some
good questions to ask him.
