Samantha does have the keel with dimensions shown in Boats With an
Open Mind. However, it is solid wood and only has about 150 lbs. of
lead, so it probably quite near to the design weight. The rudder is
as shown, including the end plate. The berth is 14 inches above the
bottom of the boat at its aft end and I store my tools and some other
seldom used things beneath it, comprising probably another 200 lbs.
of inside ballast. Also, when I built the boat I raised the sheer 4
inches.
A standard Chebacco in this wind with the same amount of sail up
certainly would have gone over further, but I think the design is
such that it would right itself in the absence of steep or breaking
seas. Bolger does show a 90 degree waterline in the plans - the boat
will float on its side with no problem.
>>> You said you had a reef in the main -- was this the first reefshown in the sailplan, did you have both reefs in, or a different
reef depth than the plan shows? <<<
My sails were made by Bohndel and I believe they are to the design
shown in the plans. I had just the first reef in the main and the
mizzen was not furled. I was beating so both sails were trimmed quite
close.
>>> I use a dinghy type mainsheet block, with a built-in cam cleat,so that the sheet can be released by a single jerk on the line (no,
not the jerk holding the line, I mean a quick tug!) <<<
I have the same sheeting arangement, but as I mentioned I reacted
incorrectly.
>>> You're making Chebacco history out there -- when are we going toread all about it, in full colour? <<<
I'll be living on the hard again in a couple of weeks. I did a first
draft about the building of Samantha for Chebacco News which I
promise to get the rewrite done soon - there will eventually be some
illustrations, too.

Hi Paul
Exciting times!
I just looked up your entry on the Chebacco registry, to see about
your ballast keel. How much does this weigh, and do you think you
might have gone over without it? I see there is a deeper rudder that
goes with this keel, can we assume you have this too?
You said you had a reef in the main -- was this the first reef shown
in the sailplan, did you have both reefs in, or a different reef
depth than the plan shows?
I use a dinghy type mainsheet block, with a built-in cam cleat, so
that the sheet can be released by a single jerk on the line (no, not
the jerk holding the line, I mean a quick tug!) I've only ever had
to let the sheet fly once, when we caught a two reef gust with only a
single reef. The boat popped up instantly. Tom McIllwraith may
remember the occasion!

I have significant weather helm, especialy in high winds. I keep the board pulled about halfway up to counter the weather helm. I would have reefed the main, and dropped the board down all the way. Would have left the mizzen up, as well.
Also, I might have considered pulling the board up entirely, this works REALLY WELL for reaching and running, the boat really flys, and barely heels at all in the puffs.

One of the reasons that PCB likes the Black Skimmer-type (i.e with
triangular main) cat yawl is that as you reef the main, the center of
effort stays in the same place WITH FULL MIZZEN. It doesn't work out
quite as well on paper with the gaff main, but I think that it points
the way to go.
Another time, I would try getting the mizzen snotter as tight as
possible to flatten the sail, then adjust the mizzen sheet to get the
amount of weather helm you want.
This comment is based on theory, more or less. I would welcome the
experience of Chebacco sailors.

As a new Chebacco builder I'm pleased to hear that Samantha handled the
knockdown as well as she did.
It's not hard to understand that the gusts were higher in between the
islands however. I sailed a lot in Greece over a decade ago, and with the
Summer Meltimi winds coming across the Aegean, it's common to catch huge
increases between the islands as the wind funnels through almost chute-like.
I was in a Jeanneau Sun Legende 41 back in 1988 and was caught by surprise
as I rounded Hydra and headed South across to the Cyclades. We were reefed
jib and main, and I still had the rudder coming out of the water. Arenaline
rush is an understatement.
As well, we lived in Vermont and I sailed Penobscot bay every summer during
the late 90s. I don't envy you dumping in Eggemoggin Reach. The coldest
water I've ever been in was in Maine in July. Thank God the Chebacco will
go 60 degrees or more and recover.
On a lighter note, it looks like Boudicea the Chebacco will get wet the
first time in Williamsburg on Sept 13th if any of you VA builders are on
line. Frantic work the next three days not withstanding. Sorry Bruce, with
my work schedule, a trip to Kingston is only a fond wish. I'll try to have
some pictures.

Hello group. It's been a while since I've been at the keyboard of a
computer. It's good to get back up to date with your posts.
I think I remember a few months back someone commenting that there
hadn't been a report of a Chebacco being knocked down - well, I'm
here to rectify that.
A week or so ago I left Bucks Harbor and sailed east down Eggamoggin
Reach with a nice fresh NW breeze that steadily increased. By the
time I headed south and southwest into the archepelago south of
Stonington I had to stop and reef the main. Then the wind started to
get very gusty - this was exciting sailing - beating with the lee
rail in the water. Then suddenly the lee side deck was under water
and I could see the ocean through the cabin window. My immediate
reaction was to push the helm down. This had little apparent effect -
I think the rudder was mostly out of the water - but the boat did
slowly round up into the wind and come back upright. (I might add
here that I had one of the most powerful adrenalin rushes of my life -
my teeth were tingling.) I started to think that taking another reef
might be advisable. I hove to and did just that. I also furled the
mizzen and tried to sail with just the double-reefed main, but found
the boat had quite a bit of lee helm and would not sail to windward
effectively. I sailed the rest of the way to where I anchored in the
lee of McGlatherny Island with the mainsheet uncleated - even with
the reduced sail had to dump the wind out of the main a few times to
keep Samantha on her feet.
I heard several buoy reports that evening on NOAA weather radio of
winds of 20 - 25 kts. with gusts to 30 kts. It seemed that the wind
was much gustier amongst the islands than it had been earlier in the
more open water. Or that might have been merely a coincidence - me
getting into the islands as the wind increased. The wind had
definitely been steadier until just a few minutes before this
happened. Letting the mainsheet run free is far more effective than
trying to steer the boat up into the wind and I'm not sure why I
didn't do that other than perhaps from habit in more moderate
conditions. (A bad habit, I see now.)
The good side of all this is the apparent safety of this design. Even
at the time of maximum heel (perhaps 60 degrees) the boat was
nowheres near shipping any water - she is designed to float on her
side and I have no doubt that she will.
