I agree that few people will get it confused with a J24. I enjoyed
this comment, quite similar to one Bolger made the day they were out
sailing the BW and the other small boat people where wearing all
their rain and wind gear and he was in a golf shirt.

"It's nice to be able to sail past someone who looks like a drowned
rat while you're sipping on a cup of coffee, lounging in your shorts
and leaning back against the hull... You have to remember to give
them a nice wave as they aren't having a good day."

My guess is that a Birdwatcher will recover from being knocked down
by any gust in flat water, and will hang pretty tough in waves up
till some point where the boat is actually rolled. The size and
shape of a wave that can do that is unknown to me, but I wouldn't
have much worry up to the breaking crests size at about 16-18kts
wind speed and 4 foot wave height. Only a guess. It may well be that
the breaking crest has to be a lot larger.

Among the unknowns is the max wind speed in which the boat can made
progress upwind. As wind speed increases, the drag on the hull
increases, but the drive is determined by the amount of heel that
can be tolerated. (In other words, as the wind get stronger, the
drag gets higher, but the sail gets reefed to the point where you
don't have enough drive to overcome the drag.) As a boat without
heavy or deep ballast, BW has limited sail carrying power, as
compared to, say, a J-24. So, BW is not a heavy weather boat by
design, and I would guess is safe in most any condition in which it
can sail upwind.

I recently got the Messing About in Boats Jan. 15, 2005 issue, and the
Bolger article on the Raised Deck Chebacco is a humdinger.

What really got me is the concept of a hinged hardtop over the boat's
center slot -- with sliding hatches built into it! I'd been
contemplating a hinged hardtop for Cormorant's slot -- to preserve
that big beautiful run of open space for airy times at anchor yet
still having security when sailing or when leaving the boat
unattended; but incorporating the slider really seals the deal. I'd
spent many hours thinking how best to do it, and then in a trice,
Bolger came and showed me the way. Says he:

"Over this 2' wide deck opening there is a 8'6" solid hatch hinged to
starboard with a separate sliding hatch at each end, integrated so the
whole thing does not have to be opened to go below or to handle an
anchor. A solid filler piece ahead of this hatch assembly and abaft
the mast serves as a preliminary lock for the mast before you hook and
tighten the lock below the deck and it keeps the rain out . . . "

For Cormorant I'll make two of these -- one forward of the mast and
one aft, with a short(1') solid section in between where bulkhead 12.5
has a 2x6 crosspiece to brace the tabernacle.

Another quotable item from that article:

-- "with other commitments running parallel, the design stretched out
interminably, a general problem for too long, as impatient clients
will attest."

Anyway -- for anyone considering any boat of this species (class?
order? genera?) -- there's a wealth of information in the article. I'm
tempted to copy the whole thing to the files just for reference.

All best,
Garth

P.S. That Birdwatcher write-up just posted is also a humdinger. I
always wondered how they'd fare in a real-life knockdown in bad
weather and waves. Good to know it all really works.
