Hull has to be cleaned?
I just read that somebody recommends a nearly polished hull for best top speed results.
My hull has some Gelcoat stripes to repair scratches from the formaly owner.
I never took care of that, but was wondering why some 4.8 RC (with the same load)equipped with Yam 60 hp 4 Stroke are going 2-4 kn faster than mine with 65 hp 2 Stroke ( Suz Dt55 with 65 carbs on). Top Speed is 28kn with 65 l Petrol and full fishing Equipment.
What do you guys think, does it make sense making a full new hull cleaning to increase top Speed ? Is it worth the work?
