the prindle manual for the 18 and 19 foot boats has some good setup and sailing guides with lots of pics

www.nacra.us/Prindles/Prindle1918-2Manual.pdf

important bit i've learned so far from it is that when setup guides say, "rotate mast so it's pointing at the stay" they mean the rear of the mast rotation arm pointing to the leeward stay. equal to about 80degrees

i had been confused as i was thinking the front of the mast pointing to the windward stay, about 110degrees rotation and obviously too much

andinista, i assume the left bit of stainless goes onto the main beam next to the dolphin striker and the right bit hooked through it and then riveted onto an alloy or fiberglass rod/stick

am taking out my bike touring watertight "sealine" drybag today as a righting aid if needed. holds 30ltr, 30kg, 60lbs so should be enough if tied to my righting line and slung over my shoulder to lever the mast up
