The boat didn't have a boom when it was given to me. I bought a second hand one and it came with no pin on the end to attach it to the mast. I would have to look at the mast again but I am fairly sure it is the old style. The boom still has the casting on the end but a hole where the pin would sit.
I believe this is what I am missing
$18 at Murrays
Is this the only thing I need otherwise?
Or do I need this?
The mast is hanging in the carport I'll have to look at it again and take a pic tomorrow or Saturday.
I think I just realized something, Please forgive me I have only sailed a Prindle 18 and mostly seen Nacras. On the Prindle the boom connects to a fixed point on the mast and the sail is loose footed. Does the goose neck on the H17 Move in the track and go up and down with the downhaul like this image?
I'll have to go find the PDF manual I had seen and look harder, it has been a while since I last looked at it.
