Re: motor mounting board rake, why?
Incidentaly, this guy LIED.
The motor bracket DOES NOT go "negative" as described. At the lowest
setting there is still "positive" rake. I.E., if mounted on a
vertical transom, the bottom of the motor would be aft of the mount
point.
Glad I bought from the OTHER guys!

No jib because you need the standing rigging to keep the headsail
luff tight. Right.
I prefer the gaff myself. More strings to play with, and you don't
have a "bad tack".

Nothing wrong with sloops, they provide a nice clean leading edge and
help improove air flow around the main mast. Oh yes; if you have a
self tacking jib, which can be a club footed jib or a more modern
version like the soling class uses tacking can be a simple easy thing.

I'm not a snob, I'm a slob!
Obviously, you haven't had the same experiences I've had, such as a
consistent preference on the part of the glass and steel icons of
conspicuous consumption to anchor directly off the one tiny private
dock on a half mile stretch of shoreline, or the need to jam a cove
with boats even though the wind was 3 knots all night. Or my friend
who was always sneered at when he wanted to race against these guys
(they really had to up the handicap when they realised he was faster
than he looked to them).
Anyway, it is my belief that people with too much money shouldn't wave
it in other people's faces, and if they do, it should be on
unique objects of beauty instead of ugly mass-produced products from
industrial designers. Besides, stories I've heard from inside a
boatshop would make me nervous to take one of these things beyond
quick reach of the Coast Guard without a thorough inspection and
refit.
When I look at a boat with all this stuff, it seems to me that it's
all selected to be the most expensive method possible, except where
it's important but won't show.

the real reason is that the motor can be trimmed in to compensate for
all the beer and pretzels us skiff types put in our bows.

Outboard engines are designed to operate mounted on a board or
transom raked 11 degrees. It gives a range of propeller thrust angle
above and below horizontal to allow for triming the boat out for
various reasons. Mounting the motor on a vertical transom will
likely make the propeller ventilate or push the bow up although small
engines may get away with it.
What's wrong with sloops? Some are beautiful in both looks and
performance. I prefer a cat ketch for a knockabout boat with minimum
rigging and ease of handling but sloops are fine in their element.

Hello,
Thanks for your email. To answer your question, no the drive shaft
would NOT be parallel with the transom mounting bracket. Tohatsu and
Nissan motors are designed with slight "negative trim" which allows
them to tuck under just a bit. However, there is a mounting
positioning pin which you could adjust to have the shaft positioned
straight up and down with no variation either way. Please let me know
if you have any other questions.
Thank you,

Maybe so. Have to ask the motor sellers.
Still, it would seam a wedge shaped board (with a 10 degree bevel
would be easier than brackets.
Or, even, two wedges to fit under the board where it mounts.

are built with this in mind. I was told once that it's to allow the motor
help lift a boat on to a plane or at least keep her nose from digging in.
My Tanaka worked okay on the Frolic with a vertical motor board because the
boat with it's rocker, would force the nose up. You may have the same
thing with the yours. Probably would not hurt a bit to build it verticle
especially on a sailboat with lot's of rocker.
On flat skiff, I believe I would put it at the angle designed. The Wyo
wants a 10 degree angle back on the transom. I wouldn't want to make it
less on that long of a flat bottom boat, maybe more!.
Jeff
The motor mount cross board in the motor well on the Chebacco is
offset on a bracket so the board is not vertical but raked aft.
Why?
Would'nt it be much easier to make it vertical?
Instant poll, people with boats with motor/slop wells. Motor mounting
board, vertical, or raked backwards in plans? How did you make it?
What do you think the reasoning was?
I'm thinking, raked back, motor business end would be lower when
motor was tilted up. Also, motors are designed for verticle transom
planing boats, so they tilt up 90 degrees.
I'm thinking just attach mounting board to reinforced corners on
transom, making it bolt upright, and forget about it.
Thoughts anyone?
