Rob pointed out in his post (on another thread) some of the
differences between the Atkins tunnel sterns and other derivatives,
but I thought I would add my 5 cents worth (inflation you know). Rob
also asked the key question of how fast you want to go.
The pages in my copy of Mr. Gardner's book are very well "thumbed" at
the chapters of those two garveys. The 18' V-tunnel is interesting and
should be fast with modest power. I have a short shaft 40HP Evinrude
that needs a hull which is why that design is looked at so often. This
motor was used in North Carolina on an 18' shallow-V plywood "well
boat", with the transom left clear for gill-netting. The well was
identical to some that Mr. Gardner specified on several of his
designs. I never liked this combination for several reasons. (1) it
lost a lot of displacement at the stern because of the well. (2) the
motors "shallow draft" feature was unusable because the propeller hit
the sides of the well if trying to make any kind of turn. And (3) the
trim angle was non-adjustable because you had to lift the heavy motor
out of the well to make the adjustment. I must add, however, that this
boat was very well used, moderately fast, and extremely economical
If you want to go a little slower and have a clear transom, the 18'
10" garvey in the previous chapter is appealing. But, to finally
answer your question, I don't think it is possible to combine "tunnel
technology" and a well with any success. You would lose too much
displacement as well as the other problems Rob pointed out.
Now to keep this long post on topic, if anyone knows of an Atkins
design to hang my 40 HP off the transom I would like to hear your
ideas, as I just haven't found anything I like. The requirements are:
to use on a very large lake with a wicked short and steep chop, cruse
speed of 15-18 mph at about 2/3 throttle, and to be built plank on
frame (no plywood available).
