So long as the sail's Dacron, & is a simple design, like cross cut, then having it trimmed to fit shouldn't be a big deal. And actually, said method is a good way to pick up sails
on the cheap
. As, even with the recutting fees
, a quality used sail that's been well cared for, is Far cheaper than a new one, for mid-sized to large boats.
Regarding the furler, find out which model it is, & then contact Harken
, to ensure that they still make the key spare parts
for it. And also ask them what they'd recommend having onboard, in terms of spares.
Then, if your wallet can manage it, buy them, along with a spare section of foil. Just in case you either break something, or they stop making parts
for your (perspective) unit. And worst case, they're always resellable.
