how much fuel would it use in a typical weekend?

Depends on how you use it. It comes with a 260 hp diesel. At 80%
of wide open throttle it will probably plane off at 18 to 20 kts if
you don't load it too heavily. At that speed it will be burning about
10 gallons per hour. If you back off to 50% of WOT fuel burn will
drop to 6 or 7 gph but speed will be quite a bit slower, most likely
not on plane.


You overestimate the fuel burn by about 50%.
It isn't a trawler, it has a high speed flat bottom planing hull with
a keel, a huge foot deep skeg under the aft third. protecting the prop
and rudder, bulged to lower the engine and reduce the shaft angle.
It will do 29 kts at WOT, 4050 RPM, burning 13.6 gph.. 3.9kt at 670
RPM on .3 gph. At 1000 RPM, 5.4 on .6 thats 10 mpg at Manatee speed.
It planes at 1400. 3000 RPM burns 6.6 at 18.6. Seems to be the speed
for best mpg. At 3500 RPM, probably about max continuous,you get 23.
Where I have been boating for 57 years, Spirit Lake, on the
Iowa/Minnesota border, it is less than 10 minutes run from anywhere to
our beach. Easy to find with Google maps.
