The fiberglass usually pops back into place but the foam remains compressed. Soft spots can be caused several ways. The most common is body weight being bounced up & down in the same spot.

What does it mean when a boat has soft spots? Soft spots on the deck are a sign of rotted and delaminated core materials.

If your soft spot is in fiberglass, however, it’s possible to salvage.

How do you fix dry rot on a boat?

Treat any wood left inside with CPES™. Cut new wood and treat with CPES™ and insert into transom, clamp/epoxy-glue it to the back of the transom, fill in all gaps with either the Fill-It™ epoxy filler or a putty-mix of the L&L Resin™, and then re-glass the inside. It’s real work.

What is marine grade plywood?

How do I know if my boat has hull damage?

“Check for cracks on the lifting strakes and cracks just above or below the chines. That is where the bottom and hull side flex in relation to one another. These are all areas of stress in the hull, and if they are moving or are compromised, they are going to show signs of stress.”

How do you check for transom rot?

Bad rot will lead to totally deteriorated wood and a lot of flex in the transom when the outdrive unit is under load. If you’re not experiencing that, then your transom overall is probably okay. You can probe with a piece of stiff wire around the screw holes and see if there is any severe softness.

What makes a seaworthy boat?

What causes dry rot in boats?

Dry rot is a process that happens to wood, usually caused by expanding fungi in poorly-insulated areas—but boats are highly susceptible to the process as well. Exposure to water on a boat is, well, unavoidable—and wood that has frequent exposure to water is simply asking for the potential for dry rot.

Can a boat transom be repaired?

Long term, the plywood in the transom looses strength and becomes very flexible, allowing the gelcoat and fiberglass to crack. While it is a pretty complicated job, replacing the transom core isn’t impossible. Transoms are usually replaced from inside the boat.

Can I use regular plywood for boat floor?

To be suitable for marine construction, panels must be made with waterproof glue and marked as exterior plywood (EXT) or marine plywood. As a general rule for boat projects, use marine-grade plywood because the wood used to make it is of higher quality with smaller voids and fewer patches.

What is the life expectancy of a fiberglass boat?

How Long Do Fiberglass Boats Typically last? Fiberglass boats can be sound and seaworthy for up to fifty years or more.
