I sail my Laser 2 out in Long Island Sound off a small island and there are typically other folks out and about to sail with/against. Every now and then we race around the island or some point or another. I'm sailing the Laser 2 solo (usually trapping) without a spinnaker and i'm wondering if theres any IRC or PHRF ratings between the L2, L, and Sunfish? how many minutes/mi should i be giving?
