Hi Howard - am NACRA 5.2 owner and we share a first name - pretty rare bread I imagine. Mine is # 1872 and is equally tired in some departments as yours sounds. I do have a spinnaler though it's not the smoothest design. I've sailed the boat three times so far but will get more time in the summer, (two year old permitting) so I am sure a few more pieces might fall off but it has been solid so far. Only real problem is the leaking mast which makes it very hard to right if turtled..
I am based in South London and sail on a 700 acre lake to the West of the city. It is set up 100' in the air so clean winds (and a swell).
Best of luck
Howard
