Well stated Kevin. Adding a small sailing rig to a basically power vessel is
not the best solution, and very probably resulted in the demise of the
concept
of 'motorsailer'.

My contention is new hull forms to improve the situation

Subject: [PUP] Motorsailers

I own and cruise a Sutton (Tarpon Springs) LWL 43 LOA 47 1966 steel Trawler
originally equipped with 2 masts and sails then converted to paravanes,
sticks
deleted, sails sold, 200,000 logged miles 5.5mpg, 900 gallons fuel, MAN 4
liter-detuned by the factory from 90hp to 44hp-1500rpm tops, cruises at 7.1
knots 1200rpm-30,000 engine hours-oil changes recommended by the factory for
every 900 gallons of fuel used--low wear long life. So an experienced boat.
Point being other than the complexity of a folding prop how well do you think
my current 34 inch 3 blader-5% more efficient than my 32 incher is going to
do
sailing. Sort of like dragging a garbage can behind the boat I suppose.
Efficient Trawlers have large props, sailboats have small props. Making
windage from sticks and sailing efficiency from prop and appature size
reduces
range increases fuel usage and isn't that beyond a "get home system" that all
this babble about motorsailers is focused at. JOLIE
