Re: [AtkinBoats] Re: I'm looking for any advice about the Russell R. design
- There have been lots of successful designs with motor wells, the Bartender
of the Northwest coast and the Simmons Sea Skiff Back East come to mind:
And a couple of friends of mine have had real good luck with the outboard
wells they've put into their flat-bottom skiffs. There's nothing wrong with
wells, they just have to be done right. Ideally, you should have the motor
on hand before you start building the well, which should be made to fit. You
want the cutout in the bottom to be big enough so the motor can kick up when
turned, but without much to spare. Likewise with the cutout in the transom
-- high enough to fully tilt the motor, but not much higher than that.

Never put off until tomorrow what you can do the day after tomorrow.
- Another of my favorites! To get the designed top speed, Russel R. has to be
built light. If you use heavier, stronger wood than the oak and cedar
specified you can trim the scantlings a bit. The best thing to do would be
to ask the local boatbuilders what they use. You'll have to take extra pains
to make any cabin, or other additions, light. Strip-planking a flat-sided
skiff seems pretty silly, and tedious, and carvel planking would be too
heavy. Lapstrake isn't reaaly all that difficult, but if you don't want to
try it batten-seam construction would be almost as light, and probably about
the same amount of work. Except for some of the interior details and
decking, Russell R. is a simple flat-bottom skiff, with a cross-planked
bottom and no bottom frames. You can do it! <g>
For a light, fast boat like Russell R. you don't want the high thrust
version of the Yamaha. There's already a watertight slop well around the
motor well in the plans. The covered motor well is one of the things I like
most about Russell R. I don't particularly like listening to outboards. :ob
