IMHO, from experience of survival of 3-5000 (based on the length of the storm and wave period for the 3 days Flying Pig banged on the rock at 60* heel) impacts during our wreck, a properly constructed box will take it easily.
While we were perched on the sides of the cabinets, talking to the USCG, we watched the entire floor (and cabinets on it) heave inches at a time as it crashed down. Further aft, the engine
was doing the same thing as I peeked in the ER door to assess water intake. I was convinced our enormous reefer project
was toast. I wasn't very happy about the tanks
under the same sole, either, being FRP.
After it was all over, the reefer came out just fine, and the tanks
had isolated small gelcoat
So, I'd say yes, if you use extruded polystyrene. On the various hard stuff insulation, iso and urethathane have a higher R but are very weak on water repulsion; ExPoly is very strong (but I still covered it in epoxy). I had direct conversations with Kollmann on the subject. The difficulty of adequately (absolute security
, and, how was I going to hang my shelving and evaporator if I had to drill???) wrapping the iso was why I didn't use it.
Totally OT, our also newly-installed PVC head plumbing
survived intact, a REALLY good recommendation for that project
if you have the ability. I can start a new thread if there is interest in knowing how we did it, but there is NO hose in our aft head
, and only a couple of short connectors in the forward head...
