As for the speed question, I opted for a 10hp motor
1. I want to be able to move along quickly if there is need to do so (such as a emergency).
2. To move quickly if I feel a desire for the cheap
3. To surf launch reasonably easily with the whole crew, dog, and supplies.
4. To carry some big, heavy metal object out to Zeehag if necessary, before her arms wear out.
5. To be able to tow my 41' ketch
through a very narrow slot or to a safe anchoring
place in the unlikely situation that it may be necessary (oh, that is not so unlikely since I have a 20' slot at high river level, just to get out from current
moorage into the navigable part of the Columbia
6. AND... get this amazing thing - the dinghy came with OARS, so I can row it tooo. Don't even have to put the motor on to row it!
It is all about options, not necessarily going fast, which appears to be forbidden to think about for some sailors.
I am a real fan of electric cars too (real ones, not these hybrids that don't get any better gas mileage than a 1972 Honda
Civic), but drive an Alfa Romeo Spyder because it is a hell of a lot more fun... and in fact, more practical in my situation.
As for the idea of having a car at the dock
. Great idea! Exactly what I will keep doing right up to the time we start a voyage with no plan to come back to the same dock
. Anyone in the Portland
area interested in a good running, restorable Alpha?
