Great tips guys,
Found the wedge thread and installed it, and went out for my second sail yesterday....
Do you remember the title of the thread? I'll also need to look at doing a mod that allows me to furl the sail from the rear without having to get up from the seat each time.
....However I I'm nealy too embarrassed to admit...I left the heavy duty wheels on underneath and didn't realise until I was out in the middle of the bay! I had to reach underneath to pull it out, I'm lucky the bungee didn't snap.
I'm sure I'll do something similar during my TI experience.
