Cheers Rumble, ill take it down there and see what we can do.
I didnt realize there is such a broad variety of goosenecks! I thought "ah yeah jump on eBay and snap one up, or at least Whitworths and she'll be right!" not the case!

Cheers lads, can anyone recommend one for a 8m trailer sailer, i actually don't like the one i have, they way its mounted to the mast is with 6 rivets, and under load looks fragile, might even go with one on a track so i can adjust boom height?
Thanks again!
