"boats designed for the bare boat trade omits them so that renters don't run them aground"
Quite correct; cruising cats are made for holiday entertainment rather than passage making, and they do it very well. However, other cats come with retractable twin daggerboards that perform much the same function as a centreboard.
for an explanation, with small illustration, of why twin daggerboards (and rudders) are fitted to this racing monohull which also has a canting keel
photo here of a cat with daggerboards:
"Twin asymmetric daggerboards (rigged to the mast for lifting power) ensure good windward performance"

As luck would have it, I spent yesterday aboard "Wings," the Newick
trimaran I mentioned earlier. Winds were 15-18, light chop on an easy
swell. We went upwind at 8,5 to 9 knots.
Yes the boat has a centerboard - draws 4.5' board down; yes, she
out-points standard ballasted mono-hulls and way outpoints cruising
cats. (There is a 40' cat in Cruz Bay named "soma" that I have not
seen but is said to be carbon-fiber and very light - 4000 # - and very
fast. I have not seen her.)
"Wings," is 36', weighs 6500# and sail area 800 square ft. She's
cold-molded ply; built in 1983; power is a Yamaha outboard. Unlike the
cruising cats I've been aboard (but have yet to sail) she's spartan -
no galley, just a shelf for a portable stove, 4 berths, marine head
forward. She'd be fine for cruising the Virgins. Though the owner
doesn't cruise her, he did sail her down here from Massachusetts.
She's beautifully made, feels solid underfoot and underway - i.e.,
doesn't creak, groan or complain in any way - just goes to beat the
band.

PS It's great to see how much interest the Galpook Bygrave has stirred
up. Nothing like getting back to basics, is there? HS
