Guys - please think about it.............
The angle you sail to windward has to be a function of the sheeting position of your headsail (as well as lots of other things).
But essentially the closer the headsail and main can be sheeted - the higher you could theoretically go - all provided the wind and wave conditions do not overcome the lesser power you have with those flatter sails
Anyone can sheet a mainsail
to the centre line or above - so the headsail sheeting angle is the one to think about.
I find it difficult to understand how a Soling (that has a very narrow sheeting angle on it's non-overlapping jib) cannot sail higher than a Farr Racer
/ Cruiser. Simply because of the differing sheeting positions of the relative headsails casued by sail size, deck
layout, stays and rig position etc.
My personal experiences sailing both types of yachts in mixed club fleets have allowed me to experienced it from both yacht helms.
With tolerably good crew one year with a Soling, to a Farr 1020 the next, to a flat out JOG 30' racer
There was no way anyone would get a Farr or any other bigger race
boat at club level to outpoint the smaller race keelboats - even if those bigger boats got to the top mark first due to extra speed.
Even more recently, on our current
Hanse 461 with a blade non overlapped headsail, we found we can definately sail higher than on our previous larger headsailed Grand Soleil 42.
The 42 was no slouch to windward (tall race rig and max deep keel) but its overlapping genoas were not cut as flat as our current
jib, nor could thay be sheeted as far inboard as is possible on the Hanse.
Of course all the other factors do come into play on ponting - not least water / wind / hull
/ crew - but all else being equal the narrower the headsail angle - the higher you'll go.
And the wider the headsail angle the lower you'll sail.
IMHO of course, it can't be any other way..............
