Mike's right. I'm learning each PHRF group treats a sprit differently.
Chesapeake Bay PHRF allows moving the assym tack forward up to 10% J without penalty to alow anchor rollers to be used. On my boat, a 35.5' long boat with 178" J, that's 17", which seems generous. But I want to install a Selden sprit at 55" which will be no penalty for Long Island PHRF, but suffers -6 seconds for Chesapeake Bay. Each PHRF group is different. The Selden sprit pole fits through a large SS loop mounted on the deck next to the tack fitting and the inboard end mounts onto a folding padeye on deck. I wanted to install a few padeyes on deck to set the pole at different projections to meet the best PHRF rating. But the Chesapeake Bay PHRF penalties are too much. 55" to 60" seems like the sweet spot, so I may just set one padeye at 55" and have fun. FWIW, I just laid up five layers of 1708 fiberglass and West Epoxy onto a thin 4" by 16" strip of G-10 that I'll cut into oval shaped pads to reinforce the deck, spread the downforce load, and raise the padeyes about 3/16". I already cut circular backing plates for underdeck. Headed to the boat tomorrow as temperatures will be 55 to 65 for a few days.
