Replacing hot water heater on an IP31.
The heater was a perfect match for the one which cracked. The Island Packet 31’s spot was under the port lazarette. It was a little tight getting in and out but went well. I had made the switch solo which extended the removal and install time. Defender priced it competitively and delivered it in one day (don’t know how they do it). Defender has been my go to for twenty years.
