Hiya,

I have a 15Ft Fibreglass half cabin (Carribean Sandpiper). It developed a
crack in the gelcoat and took on a bit of water, That has all been patched
and sorted, but I want to install an inspection port in the deck. Is there
way to work out if there are supports under the floor, or are the more
likely to be in certain areas, I do not really want to cut/damage them
installing the port. Any ideas thanks

Alan
