The reason the Chebacco centerboard is on the centerline is that it
has a shallow keel which covers a portion of the board so that it is
not quite so intrusive. Most of the remaining case is actually in the
cockpit. The keel is designed to protect the rudder from damage and
the rudder is where it is so that a motor can be mounted behind it on
the centerline. The hatch is also on the centerline so that it can
get knocked down and not ship water even if the hatch is open.

If you build the version #2 with a full glass house, it doesn't have
a centerboard and is almost seaworthy enough to go offshore acording
to PCB&F. Then there is the offshore version as well.

In Phil we trust:-)
As of yet, I have not acquired a taste for leeboards or most of
Michalak's designs. I tend to be a litte more traditional from an
aesthetic standpoint. I think the Chebacco is aesthetically the best
design of Bolger.

I dont know why more boats are not designed with offset
centerboards. You dont have to cut through the hull at a point where
you have a lot of joining along the keel...move it over a foot or so
against the galley and offset the entrance to the cabin a bit. The
Princess 22, 26 from B&B are like this. The deadrise at the point of
the centerboard is not that sharp as to cause more than a marginal
performance issue on one side of the boat.

Not to muddy the waters, but have you considered Jim Michalak's
Caprice? It's 25' x 6', multichined like Chebacco, has a pivoting
leeboard (so it gets the CB out of the cabin), and has water ballast
for added stability. Check out Chuck Leinweber's, a sight to behold:

I started out with a serious longing for a Chebacco 25, and veered
off toward Caprice, then somehow worked my way round to asking Jim to
design a 31'x 7.5' version of Caprice -- Cormorant -- to accommodate
my family of four on week-long gunkholing/beachcamping cruises. He
doesn't sell the plans for it yet, but will soon. (Mine's not close
to being done, but maybe by this year's end.)

All best,

Hi Joe,

Have you looked at this site?

http://chebacco.com/

I think the 25-footer can be built using wood-strip construction with
a plywood bottom. If you go to the above site and click on "New
Articles" and the first article on the August 2003, newsletter, you
will find a link to the boat "Two Grumpy Old Men". It shows a photo
sequence of a standard Chebacco 19 built in that fashion.

If you check out the "registry" link you will see a photo of Richard
Spelling's cabin version of a standard 19 footer. To my mind if one
were to build the 25 footer in strip-planking and added the cabin
conversion which includes a built-in head, bunks and cooking area,
you would have an excellent motorsailer.

Also in the registry is the email address for a fellow in Australia
building "Mudlark" a 25 footer. He is making some drastic
modifications that I don't think PCB&F approve of, including
leeboards.

The centerboard case in the 25 footer is not so intrusive as part of
it is located in the shallow keel. If the keel was a bit deeper and
some lead added, the centerboard could be left out altogether, but
it's upwind performance would suffer somewhat. (Means you start the
motor a bit more often.)

With a ballest keel and the pilothouse it would have offshore
capability and with a high thrust 15 hp Yamaha it would plane.

I would of course check this all out with Mr. Bolger. All the offsets
for building the molds are in BWAOM.

I love this design:-)

You may be under a misapprehension. The berths are marked 'pipe cots'
which implies a metal pipe perimeter with canvas slung in between.
There might or might not be a thin mattress. These would not be
rolled. The 'stowed' position is on its side against the side of the
boat.

I've never heard of any finished Chebacco 25 of any construction, and
I have never heard of plans for any construction besides the glued
lapstrake. I feel it would be a very, very,...,very desireable boat
but it is pretty big and complex for an amateur, and hence, expensive
for a pro.

Peter
Any thoughts about offsetting the centerboard against a longitudinal
to allow for more room in the cabin? My experience with other
designs is that it doesnt significantly effect sailing performance.

Also...the Chewbacco 25...seems that there should be suffucient room
to make real berths rather than canvas roll ups. Any comments here?

Last thing...Has anyone built a 25 in sheet ply construction like the
standard version? I have not seen such a design in the book.
