Spider cracks in gelcoat are common on Bay boats. Most are cosmetic. Some signal serious structural problems. Here's how to tell.
What to Check
1
Star cracks at impact points
Usually cosmetic — from dock impact or dropped tools. Repairs nicely with color-matched gelcoat.
2
Long parallel cracks
May indicate flexing in the laminate — worth probing for soft spots.
3
Cracks at hardware
Often water intrusion at bolt holes — needs proper re-bedding before cosmetic repair.
4
Cracks at hull-deck joint
Get this looked at — a separating hull-deck joint is a real problem.
