Welcome from another US member. Nearby (relatively) to boot. I'll have my SR 5.4mR down in Newport a bunch this summer for regattas. Where in RI are you?
I suddenly feel like an old-timer here, with all the new US RIBbers showing up all of a sudden, lots with Seariders too!
BTW, I think you're out of your gourd if want to beach launch that boat by hand.
