Speed

I do not have much experience with outboard powered ribs hence my question.
What max speed can be expected from a 650 rib with 4 persons on board, full fuel (150 ltr) and powered by a 150 HP outboard engine. Calm conditions of course

I have a Porters Renegade 6.5m with a Yam 150 HPDI and get about 42 knots three up.

Had a 6.6 running a 150hp optimax and that was early 40's

Many thanks guys. Most helpful.

Probably anywhere between 36 to 45 knots, depends on weight onboard including weight of people, if some one has eaten too many pies they could effect speed and other things. I had a large friend onboard one and had to sit them in the middle of the rear seat or the boat leaned too much.

Average prop 40 knots

About 2.5 knots faster than your 750!

and I have got 320 HP . Nice film you took and a pity I did not keep up with you a little longer and came a bit closer.
Anyway I am now a proud owner of a GoPro
