Am I being naive...??
I have been thinking along similar lines - just not got to the point needing to do anything about it
is to only start squirting foam after
a holing event - and not neccessarily where the hole / crack is!
The basic idea being to displace water back outside (water won't rise above sea level - leaving aside the effects of motion).......with a few semi watertight doors / emergency
bulkheads should be able to restrict the serious flooding to 1 in 4 parts
of the boat (won't be bone dry elsewhere - but should not be flooding either)...........and then use foam (squirted inside a bag
placed inside a locker or 2 to remove places that water can fill (I figure that a hole in the hull not so serious with only 20 gallons inside and not 100!) - will need to experiment
on all that
, maybe simply a bin bag?, or a holdall? - or even some of those sealable plastic holdalls (so that the foam does not get sucked / washed away. and clean up should be easier
). Am expecting that during this process the foam won't stay dry, and also afterwards - but as long as it does not waterlog (therefore defeating the entire purpose
) then I can live with not being durable after a year or 2
Time will tell on how all that goes (or hopefully not!
