Why Hull Damage Gets Worse if You Ignore It

A fiberglass crack that looks purely cosmetic usually isn't. Even a small stress crack that doesn't penetrate the full laminate gives water a path into the core. Fiberglass hulls on most jet skis have a foam core — when water gets in, the foam absorbs it and the hull gains weight, loses buoyancy, and eventually starts to delaminate. What costs a few hundred dollars to fix now can become a structural repair bill later.

If you've hit a submerged dock, run over rocks, or the ski has taken any significant impact, get it inspected. Sometimes damage that looks minor from the outside has flexed the fiberglass enough to crack the laminate underneath. We've seen it plenty of times.

What We Fix and How We Do It

Stress cracks and spider cracks — These typically appear around cleats, lift eyes, and along the keel. We grind out the damaged material, lay in fresh fiberglass, sand, and refinish with color-matched gelcoat. We're fixing the structure, not covering it up.

Impact damage — A hard hit leaves a dent, crack, or crease. We assess the extent of the damage — whether it's surface level or has compromised the laminate — and repair from the inside out. Structural integrity first, cosmetics second.

Dock rash and scratches — Deep gouges and gouged gelcoat can be filled, sanded, and polished. Color matching gelcoat is an art and we take it seriously. On older skis where the original gelcoat has faded and oxidized, we'll discuss what's achievable before we start.

Delamination — When water has already gotten in and the layers have separated, we cut out the damaged section, dry it completely, and re-laminate. This is more involved work but it's the only way to actually fix it.

We work on Sea-Doo, Yamaha, and Kawasaki hulls. NanoXcel and NanoXcel 2 on Yamaha need a slightly different approach — the material is different from standard fiberglass and requires specific repair techniques. We know the difference.

What We Don't Do

We don't skim body filler over cracks and paint over them. Body filler is not a structural repair and it fails. We don't promise that older faded gelcoat repairs will be invisible — we'll be honest about what's achievable given the age of the gelcoat and the extent of the damage. And we'll never tell you something is structural when it's only cosmetic, or cosmetic when it's actually structural.

Common
Questions.

How do I know if my hull crack is serious?

If the crack goes all the way through to the inside of the hull, it's structural and needs to be repaired properly before you ride again. If it's a surface crack in the gelcoat only, it's cosmetic but still worth repairing before water gets in. When in doubt, bring it in and let us look at it.

Can a gelcoat repair be made invisible?

On a newer ski with unfaded, unoxidized gelcoat, a properly done color-match repair is very hard to see from a normal distance. On older skis where the gelcoat has faded from sun and salt, the repaired area will typically be more visible because the new gelcoat is brighter than the aged surrounding material. We'll tell you what's realistic on your specific ski before we start.

How long do hull repairs take?

Small crack repairs can be done in a day or two. More extensive damage, delamination, or anything requiring multiple layers of laminate and full gelcoat finishing takes longer. We'll give you a timeline when we assess the damage.

Do I need to fix dock rash before winterizing?

Ideally yes — any exposed raw fiberglass or gelcoat that's cracked lets moisture in during storage. It's better to seal it up before the ski sits for months than to deal with what that moisture does over a winter.
