Hi all,
Recently, when out sailing in moderately strong winds, i have noticed a humming sound when planing. The sounds seems to have two 'frequencies' which appears to depend on how fast the boat is travelling. Originally i thought the sound was due to the bow being out of the water and the wind whistling between the hull and the water (stupid idea i now have realised ).
On doing some research in my copy of the Rya Laser Handbook and on the web, i now believe the sound is due to either the foils being misaligned or due to the trailing edge of the centre board not being very straight. The problem i now face is that i do not know which of the possible causes is to blame and once i determine which issue is causing the humming how to go about fixing it.
Any ideas? All help big or small appreciated (the sound nearly drove me mad last night so time has come to fix it!)
Cheers
