Most boat connectors that enable direct hook-up to dock hose bibs are pressure regulated to preclude the damage dhays rightfully warns against.
That said, I would hate to bet my boat on that connector being foolproof. Let's face it -- if one on an R/V fails, you've got some wet carpet; if the one on your boat fails, you're now a submarine owner.
Is it a convenience? Maybe so. Just be very prudent as to how you use this convenience. I'd recomend against it, but if you do decide to go that route, consider using it like you do with propane -- only pressurize the system when you actually use it.
