the extra insurance isn't bad, I got it so I could do the ferries and coastguard boats that come into dry dock. the tight spots just suck. but you get to charge a LOT more for the hassle. Ran my Porty from the top dock and just ran hose into the boat, HWE most of it with the wand, then finished up the details with the upholstery tool. 50ft was more then enough.
