I bought a 1992 CHALLENGER 25 that is really beat up. My concern is for damage around the dive door, where delimitation and cracking exist. I assume in the laminate there is an aluminum plate that is corroding and expanding, and that is what is causing the cracking in the fiberglass.
Q1: what is the structure around the dive door on a 1992 CHALLENGER 25 boat?
Give me advice before I start cutting open the area around the dive door. I have restored several Boston Whaler boats before, but never one with a dive door.

Re: 1992 Challenger 25 Dive Door Structure
I have never seen aluminum expand in volume due to exposure to the elements. Typically aluminum just develops a surface oxidation. I cannot imagine that an embedded aluminum reinforcement plate would undergo an expansion in its volume sufficient to cause displacement and cracking of fiberglass laminate. An aluminum plate might gain a few thousandths of an inch in a surface layer of oxidation.

Show pictures of the area [of the CHALLENGER 25 dive door that has damage]. They might save you from a thousand wrong answers.
Three door sizes were offered.
Q2: what is the width of the dive door under discussion?
Q3: is there a stainless steel guard around the door opening?
Q4: do you have the door?
Q5: do you have the ladder?
