Desperatly looking for an answer
Hi , I'm having trouble with my sailboat speed...Beneteau 423 2007
Got the boat last year, she had a new paint on her( green ablative paint ) and all season was doing good speed (averaging the 7Kts) We spend the winter in the water since we are live aboard and now, I cant seem to past the 6 Kts mark.
First I thought it was the bottom that was dirty which it was.... I cleaned it really good with a brush and didnt change a thing. I then decided to take the boat out of the water for a nice paint job. Just did that last week. Sanded off all that old paint and put a new coat of $$$ Micron CSC ( 4 gallons total )+ waxed from the water line to 16 inches above. To my disappointement, not going much faster. At same RPM ( motoring ) I gained 0.3 kts and can't get more than 6 Kts at full throttle.
All my settings are the same:
GPS ground speed in Kts
motoring or sailing, no speed ( so that takes the rigging out of the question )
I think it's pretty much it...any ideas what to do next
could it be the prop that slows the boat down that much...it looked pretty good to me...not sparkling or anything but in good shape!
