Everyone is guessing. Shoot some video, take some pictures, show us the sails, show us the tell tales. Show us the grinders (genoa) and trimmer (main) in action.
We do... and we did this week. Others have suggested that was the wrong thing to do. Better to twist off the leech than increase the power when heeling excessively. Coincidentally we do point higher with the cars further back. We have tested that empirically.
This is not a complicated boat and not a complicated problem. Some of the solutions being offered to you are directly contrary to all the sail trim guides.
I am trying to help so don't take offense. Have you ever been on an experienced race
boat? Have you ever had a sail trim class or had someone join your boat and teach?
I will submit that at this point you are chasing your tail, getting tons of conflicting advise and not getting anywhere.
You can't learn this from the internet
. I thought I was doing OK until I joined a race
boat. and watched the trimmer take in 5 grinds on the vang/mainsheet, 2 grinds on the outhaul
, 3 grinds on the genny - although the genoa
at times does need to be cracked off for pointing.
You can hear the blocks and gear
moan and creak when things are getting tight enough.
So as not to sound like a broken record
I will bow out with this.
- You aren't getting the main near flat enough
- You aren't pointing high enough and "luffing" off the excess power you have
- You are getting boat speed at times but the boat is in first gear
and bent over so the sails
can't work together.
I only say this with mild confidence but there have to be hundreds of this boat out there, many of them doing can races and I have not found any significant Google
hits about the problems you are having.
Blown sails notwithstanding.
I always defined close hauled as pointing as high as possible relative to the wind on a beat with the sails trimmed in tight and the boom mostly centered, not by how many degrees off the wind we sail. We point as high as we can without luffing the genoa.
This is not accurate. The sailing point that you are on is dependent of the relative wind. If the wind is 40 degrees off the nose you trim for 40 degrees - you don't simply trim for "close hauled" everything tight.
The sail is an adjustable airfoil that is only efficient at one angle of attack for one set of trimming. you adjust the sails for the relative wind regardless of the direction the bow is pointing.
Someone has suggested genoa car sheeting angle - inner track vs outer track. This could be a possibility but I doubt it as you say the tells are breaking evenly and that they genoa backwinds the main with traveler down.
