Please take a few minutes to review our web site. If you are in the
market
for a great performing and fuel efficient boat, the Quonset Point 25
may be
for you.

Hamilton Jet Water Propulsion.

Cleverly disguised spam there. good job.

Now I have a question. Why would I want a jet drive on a boat like that
as opposed to propeller propulsion. Aren't propellers more efficient?

The new Hamilton low pressure jets are about 95% prop efficiency these days.
No worries about hitting stuff. and skinnier water operation. Seems high on
the price for a 25' boat. When I can get a fully equipped Davis Rock Harbor
(Morro Bay, Cal) for that or a little less. Interesting thing about the
jets (I own an Aluminum jet drive boat (21', and only about $43k for a new
one). Couple of years ago, I took the "Fast Ferry" from Barcelona to
Majorca, Spain. 97 meter boat, twin jet drive, 47 knots. With 300 cars and
800 passengers, and a few semi's also. Mine only does about 40, with a 351W
Ford. The ferry was 38,500 HP.
