Regardless of the type, you should always have some method of plugging a leak or broken valve. I have the soft Wood cones near each thru-hull as a safety matter.

Since most through hulls are bonded to the hull using some impenetrable goop like 3M 5200, you’ll risk damaging the laminate if you try to muscle the through hull out of the hull and I had no issues unscrewing the gate valve out of the through hull threads. I was informed by folks much smarter than me, that gate valves can be very prone to failure and when they do fail, there’s no means of shutting the flow of water through the valve. Rather than questioning, I took their advice and got all the gate valves out of the boat. Chuck Gilchrest SV Half Magic 83 35 Landfall Padanaram, MA
