Dunno, if your gunna buy stuff from bunnings, why not just go to one of the windsurf shops and buy a mast bag.
I wouldn't mind betting they're not that expensive

I made mine with old pairs of jeans, just using the legs. A bit of sawing machine, some separation in the middle for the 2 halves, works perfect. Just have to rinse it now and then.
I can't send you a photo now as I am overseas. (Actually working on the Gulf of Mexico and I wish I had my gear right now, 20 knots, not much sea, miles and miles off shore and it's around 32 degC...)

Thanks for the feedback guys. I was hoping someone would have said "..go to a plumbers supply as they have cheap rolls of insulation foil tubes"...but that didn't happen....sigh.

However, I do have a domestic sewing machine but it can't handle heavy threads so making anything stronger than a dilly bag is not possible. Mark_australia your idea sounds the most convenient re; old one-piece mast bags cut in half. Pity I chucked my old Gaastra one out years ago, that would have fitted 2 x 2-piece masts. Something will turn up.

New masts usually come with a bag, right? Masts break, but the bags live on. So theoretically there should be almost as many mast bags surviving today as there have ever been masts in all of windsurfing history.

I think I bought my proper mast bag for about $25 from memory, so they a pretty cheap!

Yup saw that the other night. It's no hassle to me, I get a kick out of making things, remember the old Drum tobacco ad slogan, "Roll your own."? That's me.

But....
