Sea Spray 15 and the AMC Moth 15 both have a 77.9 portsmouth number from US Sailing. In the US no distinction is made for sock or halyard rigs. Only sail plane and area would change that.

You made a good show at SF when your boat was all in one piece...lmao

I hope you will make the trip back next year. I am re-doing the Blue boat..less weight,a tramp that will stay on the boat, and no more carring 5 gallons of water in the port hull..lol.. found the leak.
