Re: Powering the Snow Goose
Hi Stan,
Since you asked for some comments etc.....here are mine;
I do not recall whether you have kept the keel configuration as per
plan but if you have then I cannot see how an outboard unit will
suffer damage in an accidental grounding since the keel/rudder
assembly is lower then the outboard's prop.
My next concern would be weight.I suspect,but cannot
confirm,that the entire weight of the engine/fuel tank/paddle
wheel/bracket,struts etc....hanging off the stern combined with the
additional weight of your pilot-house plus at least one person in the
pilot-house minus the weight of the mainmast up forward will have
SNOW GOOSE powering along with her nose aimed up to the clouds.Of
course you could always add some lead bricks up forward to trim her
level but by then SNOW GOOSE will weigh a whole lot more and will
perhaps require a slightly bigger engine and or bigger paddle
wheel,which will weigh a bit more thus requiring more trim ballast up
forward.This process,I suppose,would go on until you end up with the
very first MICRO-SUB at which point I would humbly suggest a name
change to:PLATYPUS.
Anyway,Stan,just my two cents worth but there really isn't
anything wrong with a good little outboard off the stern especially
when you consider the ease of maintenance(just haul it off to the
dealer) and some wonderful manouvering tricks like 360 degree turns
with rudder and outboard"hard over"!
Best of luck!

Hi All,
Now that the pilot house is well in hand, and all the major work
done, it is time to work on powering up the Snow Goose. After much
jumping back and forth, from outboard, to inboard, then settling on a
Stern Wheel drive, it is time for the work to commence. The reason for
going for the stern wheeler, is several fold; 1) It looks cool, 2) for
river use, it will be less prone for damage than an inboard propeller,
3) The rocker of the hull is perfect for a stern wheel, 4) it is highly
efficient, And 5th) It may not be sails, but it is cool! If this won't
start a, "what the heck is that", conversation, I don't know what will.
;-)
The wheel, as designed, so far, is to be approximately four feet in
diameter, have six blades, and be four feet wide. The engine, I had
several to choose from, has come down to the engine and drive train from
a golf cart. It is eight horse power, has forward and reverse, has an
electric start and charging system and the whole thing will fit in the
motor well behind the cockpit, with little to no, hull change. As far as
the engine power is concerned, to achieve top speed, I need about thirty
RPM from the wheel, so with this amount of reduction, I will have more
than enough torque. The only major redesign will be the steering. From
the information I have been able to glean from the web, the normal setup
is to have four rudders, two in front of the wheel and two aft of the
wheel. This will call for some empirical engineering when the time
comes.
Please, any and all comments and/or suggestions, are not only
welcome, but are requested. ;-)
Best regards, Stan, Micro Tugger, Snow Goose.
