I want a kayak-length jacket with a camelback water tank sewed in the back so I can drink water while I'm on the wire or in a regatta
Magic Marine make one exactly like you describe. Only problem is it is not US Coastguard approved because it's a bit light on flotation. I wouldn't use it for an offshore distance race but it should be fine for racing round the cans. It is CE approved so should be safe enough.
Click on the Other Flotation link on
the Magic Marine website. The model is the "Regatta Jacket with hydro pack".
