Darryn,

I've never heard of Windslyce before. It looks like they make some good gear.

The track I had in mind was Harken.

Simon,

You may not need to take the track off at all. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> Just put a long ring spanner over the inboard bolt head from inside the beam and just undo the nut from inside the hull and lift the whole beam assembly off with the track still in place. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

Regards,

Peter
