Alctel:
Kudos to you for entering your Cherubini Hunter in a race.
I did start the project to install T-tracks on the main deck close to the cabin top. But then put it on hold while moving on to other things (mostly non-boat). Also the installation became complicated than originally contemplated because the deck, right next to the cabin top, although non-skid in appearance, is not cored there. Just a single layer of 1/4" fiberglass. I was concerned about too much flexing under the stress of a highly loaded jib sheet in the frequent 25kt winds on San Francisco Bay. = Possible damage to the deck. I thought it important to have the 1/4" thick FRP interior liner participate in the strength of installation. But right underneath my desired T-track location is the part of the liner in which the AC and DC wiring is routed. And a 2.5" gap between the deck FRP and the liner. I have a solution. But with the need for 14 screws/bolts for each T-track, effecting it is time consuming ... and thickened epoxy demanding. Will get back around to it as the summer progresses. But initially I will do just one side and will first install the T-track temporarily to first confirm that pointing is actually improved enough to make the installation permanent and to do the other side. If pointing isn't really improved, I'll consider it a failed project. And fill in the 5/16" holes I drilled in the deck with epoxy and then paint to conceal.
Regarding Don Guillette's excellent suggestions to experiment with barber-hauling. Over the years, I would often barber-haul inward from the normal toe rail sheeting position. But on San Francisco Bay, we generally don't stay on a point of sail for too long. And due to suddenly shifting wind direction and gusting wind speed, the jib sheet needs frequent tending. Often immediately with virtually no notice. I sail solo or mostly with people who can participate only in much calmer conditions. So that effectively is solo sailing for me as well. I realized the delay in first needing to release the barber-hauler prior to easing the sheet was potentially dangerous. So barber-hauling was not a sustainable option.
I did observe that barber-hauling the jib, compared to our toe rail sheeting, did improve my Cherubini Hunter 36 pointing. But really not all that much. Other similar size cruisers with deeper keels and different hull shapes continued to point significantly better upwind than me. And against J-boats, not only would they still arrive at the opposite shore well ahead of me, but also a further half mile upwind!
Afraid that our Cherubini Hunters will never be pointing standouts.
When I do get my inside T-tracks installed, the sheeting will still be run out-board of the shrouds. Our shrouds are positioned pretty far out, about 8" inside the toe rail, compared to more performance oriented boats which can have the shrouds intersect the deck right next to the cabin top. But still I think that T-track sheeting, which will be about two feet inside the toe rail, will allow better overall sail shape on a close-haul. My current inclination with our toe rail sheeting is to over-tension in an attempt to bring the jib clew in-board as much as possible.
