I second the comments above. Even though the sails look new, they could be stretched or just not well cut. You can consult with a sailmaker
for an opinion. Rigging
tension is also good to check. I would put as much or more emphasis on the headstay as that controls the luff and sag of the jib
. The genoa is too large for good windward ability. Change to a non-overlapping jib
, 100% LP, just enough to fill the fore triangle and you'll have better pointing ability. Yes, check the sheeting positions for both the jib sheets
and the main sheets
because they control the twist and set of the sails. Make sure your halyards are tight (giving tight luffs to both sails), that your downhaul on the main is tight, and that the outhaul
on the main is tight. A book or course on sailing trim is highly recommended. Finally, if you have not already, check to make sure the bottom of the boat is clean (hard to get dirty in a fresh water
lake). And the propeller--do you have a feathering or folding propeller
? If not, then the propeller
drag is holding you back.
I grew up on and learned to sail on Lake Superior also, and still have a home in Marquette, so I am familiar with your cruising grounds a little.
I hope that helps.
