Thanx to everyone who replied or re-posted my questions!
I've read all 18 pages of the other Autoprop tread. It was informative,
but, it often digressed into maintenance
and customer-service issues.
Being a former military & current commercial
pilot, who has operated mostly
propeller-driven aircraft, I like the aviation/marine-propeller comparisons.
Especially enjoyable, when boat-propellers are said to produce "lift" in the
incompressible medium of water?
All speed is relative, of course. So when we're talking about the difference
speeds of relatively small vessels, surely every knot
Being a powerboater, I've always solved
my speed problems by adding HP.
I look forward to learning
how the power of wind
can also be applied.
I'm looking for a 50/50 motorsailer
as a transitional vehicle, while I learn to sail.
By that I mean, it should have a "strong enough" engine that it can reach hull-speed,
under moderate conditions, motoring alone. Likewise, given moderately "strong" winds,
it should be able to reach hull-speed using sails alone.
If it requires both, to ever attain hull-speed, then I need to look at another boat.
Theoretical formulas indicate that most motorsailers are technically overpowered?
But, lacking real-world experience, I'm asking if this is true?
I want to buy a properly-powered motorsailer
, and wondered if the
(expensive) Autoprop might maximize a slightly under-sized engine?
Or should I spend the same funds re-re-powering for more horses?
