Beneteau 36CC does not reach hull speed
I own a 1999 Beneteau 36CC that I purchased new in 2000.
She is equipped with a 27HP Yanmar 3GM30F and is fitted with a 3 Bladed MaxProp.
I am quite certain that the pitch is set correctly because with full throttle, the engine RPMs are 3600.
Anyway, my situation is that last weekend my boat speed was 5.1 knots at 3200 RPM. Calculated hull speed on the boat is 7.48 knots.
There was a 9mph head wind and a .5 knot current against me, but 5.1 knots seems a bit low.
My bottom was cleaned a couple of weeks ago. Also, I was carrying a full load of water and fuel and I do have an all chain rode.
My question to other 36CC owners is, "Does this speed seem normal to you?"
