my inflatable boat seems to rise up then flatten out repeatedly as I go along like the air is moving forward and back when its planning it is a 3.8 m boat with a 15hp on the back with an inflatable keel any advice gratefully accepted. David
Have you tried redistributing your weight? My Zodiac
was doing the same thing and by putting my cooler in the front seemed to help. My boat would only do it with just me in it but not with another person onboard. I also put a hydrafoil on my motor and that improved things alot too.
