TWL: dinghy plans

I'm pondering the hardshell/inflatable question myself. My 26 Tolly is
just over nine feet at the transom and has Weaver davits on the swim
platform. I need to be able to carry my wife and two growing kids. I've
got a 20 hp outboard that I could use on a larger inflatable and save
the cost of a new motor, but I haven't found a nine foot inflatable
rated for 20 hp. There are some 10.5 foot models that are, but these
would extend beyond my transom. I don't know if that would be a big
problem or not. I seldom dock except for in my slip and my stern doesn't
go all the way in my slip.

Now I get by towing my 13' Whaler as my dinghy. Being on the Mississippi
1830 miles from the Gulf of Mexico makes fulltime dinghy towing doable,
but I'd like something I can raise on the platform. The boat does have a
Forspar hoist for an outboard, so handling the 20 would be possible, if
not easy.

The 10 foot Livingston looks like a capable hardshell, but I'd have to
get a smaller motor. I'd like to get a long shaft, high thrust Yamaha
four stroke 8, and make a mount on my swim platform for a get home
engine. I'd like to use this on the dinghy too, but all small dinghies
I've seen use a short shaft motor.

This brings me to the idea of building a dinghy and modifying the plans
to accommodate the long shaft. I am considering John Gardner's 9 1/2
foot pram as described in chapter 3 of Building Classic Small Craft. It
is easy to build and can carry four. I don't know if it's the best
candidate, but it's at the top of my list for now.

Questions:

Is it really inadvisable to have a dinghy that sticks out a half-foot on
either side of the boat when raised on the platform?

Does building a higher transom on the dinghy to accommodate a long shaft
motor sound like a bad idea?

Does anyone have suggestions for home-buildable alternatives to the
Gardner?

Thanks,

Jack Ray
