Thanks jl. Had a good look at the go joe and, daaaaahh, yes its easy to remove the bladder because there are two zippers. bladder is now out and has two rips one 2"and the other 1”. I suspect this happened with too much compression packing go joe with the kites in the golf bag on my recent trip to Aruba. Yes the fins were removed. the last time I tried to inflate the bladder was crooked in the sleeve and I tried to pull it in place half inflated. The pulling likely cause the small tears to get larger. Live and learn! I will try and get a replacement bladder from OR. I will ask my local kite store silent sports to order one. I bought the go joe there and they provide excellent service. I think this will be easier and more sturdy than a repair. I have never repaired a bladder before. Any advice?
