so i need to cut some access panels into the deck for the new leaning post. i've never done this before so i have a few questions. how do i know there is not a stringer where i'm locating the panel? is it just a crapshoot or should i consult the builder for some sort of plan. and when cutting, is a jigsaw the best tool to use? i'm worried that even with a short blade i will cut something else underneath the deck - my boat is pretty small and i'm sure alot of space underneath is occupied.
