Joey,

Welcome to the Mosquito class. I hope you have many great adventures on your Mozzie. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

Ask away. That's exactly what this forum is for. Everyone who visits and contibutes on this forum are only too willing to provide assistance no matter how small the issue. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

The gooseneck rod does just slide onto the boom which should have an end fitting with a matching hole. If you have a boom vang then it will stay in position and won't come out.

If you don't have any fittings on the boom then it's off to the chandler to get some new fittings. Check out the Ronstan catalogue on line to see what you need.

Mast rotation will only be restricted by the diamond wires and everyone is always trying to get maximum free mast rotation. Yes there has to be some limitation of mast rotation otherwise the sail won't align with the back of the mast section and there may even be too much stress on the mast. The amount of mast rotation relative to the boom and sail is limited by the rotation bar located on the mast just below the boom. I think that's what you call the mast arm. A piece of 6 mm dia. rope is mounted on a saddle rivetted off the boom just rearward of and close to the end of the mast rotation bar. The rope is then passed through a small pulley on the rear end of the bar then back onto a cleat mounted on the boom. This will limit the mast rotation and provide some means for adjusting when sailing.

Good luck with sorting out the setup and getting out on the water.
