The Numbers

Just the Facts Please

Analyzing The Data Reveals The Pros and Cons of Each Package.

The Inboard (2/435-hp Volvo D6 diesels)

Total Fluid Load: 1,256 lb.—129 gal. fuel (922 lb.) and 40 gal. water (334 lb.)
Total Boat Weight (official weight plus Total Fluid Load): 14,688 lb. 

Top Speed: 39 knots @ 3620 rpm, burning 42 gph for 0.93 nmpg

Cruising speed: 32.8 knots @ 3000 rpm, burning 25 gph for 1.31 nmpg
Cruising Speed: 26.9 knots @ 2500 rpm, burning 16 gph for 1.68 nmpg

Simplicity is the key to the conventional setup, particularly on the underwater side. Props, struts, shafts, rudders ... that’s basically it.

The Waterjet (2/435-hp Volvo D6 diesels)

Total Fluid Load: 1,977 lb.—218 gal. fuel (1,559 lb.) and 50 gal. water (418 lb.)
Total Boat Weight (official weight plus Total Fluid Load): 15,921 lb. 

Top speed: 39.7 knots @ 3540 rpm, burning 43 gph for 0.92 nmpg

Cruising speed: 29.5 knots @ 3000 rpm, burning 26 gph for 1.14 nmpg

Cruising speed: 17.3 knots @ 2500 rpm, burning 15 gph for 1.16 nmpg

Fun is the essence of jets. They run in shallower water than most other systems and often produce sports-car-type handling.

The IPS (2/300-hp Volvo D4 diesels)

Total Fluid Load: 1,315 lb.—150 gal. fuel (1,073 lb.) and 29 gal. water (242 lb.)
Total Boat Weight (official weight plus Total Fluid Load): 16,671 lb. 

Top speed: 34.3 knots @ 3400 rpm, burning 29 gph for 1.18 nmpg

Cruising speed: 29.8 knots @ 3000 rpm, burning 21 gph for 1.42 nmpg

Cruising speed: 23 knots @ 2500 rpm, burning 15 gph for 1.53 nmpg

Maneuverability is the IPS forte. Add a trusty joystick and there’s almost no maneuvering situation you can’t easily handle.
