I almost got one of these: http://www.realwatersports.com/ion-trav ... s-ax-black
but none of our New Zealand distributors carry them and I was quoted almost as much in freight as the price for the actual product for delivery to New Zealand.
So last night I got the angle grinder and sanding disk out and cut and smoothed off the hook on an old wind surfing harness. Fitted it with a loop of rope around the centremost belt slots and then one of these: http://www.anzor.co.nz/marine-hardware/ ... ap-shackle
around both sides of the rope loop.
Also, because I've injured my ribs before with that harness riding up, I cut the shoulder straps off of an old flexfoil kite bag with a broken zipper and re-purposed them as leg straps to make the harness into a seat harness. I used a "speedystitcher" hand sewing awl to do the sewing with thick waxed nylon thread.
But for people buying new harnesses, I like how the ION brand has a range of interchangeable bars with good padding to hook into.
If you want to make gear with rubbing surfaces last longer, try a fresh water wash after use and then spray the rubbing surfaces with silicon lubricant every so often... same with your kite pumps.
