A Little About Gel Coat

GRP/Gel coat is a form of resin which is applied to the surface of your boat in layers and when cured forms a hard, non-porous flexible finish. It has excellent impact resistance and in most cases can tolerate long term immersion in water. 

Your Gel coat is vital to the performance of your boat and with proper care, it can make your boat look good for years to come. 

When your gel coat becomes scratched and gouged, it can start to look really bad and parts of the boat might even start to show because of the damage underneath the surface. You also run the risk of being exposed to harmful UV rays that cause blistering on your gel coat when it’s damaged.

BowToStern’s repair service is designed to expertly fix these types of damage, giving your hull life back at a low cost. We provide service throughout Southampton, Hampshire, along the South Coast including Southampton, Hamble, Poole, Weymouth, Portsmouth, Gosport, Lymington, Hythe and the surrounding areas..

Why Should You Get A GRP/Gel Coat Repair Done?

Wear and Tear

Boat owners who live aboard their craft are well aware of the wear and tear that the boat takes. While you can scrub out your boat when you use it, wear of the fibreglass surface is inevitable. Eventually, this can lead to cracking on your boat and other things that should be attended to immediately.

If you have rock chips, cracks or waviness in your gel coat, a full fibreglass repair with another layer of gel coat can be done to restore the surface. All too easily ignored, these imperfections can catch water and dirt and cause further damage to your hull, reducing the lifespan of your boat greatly. A new coat of gel coat on top will ensure that no debris or filth gets stuck in it and will essentially give a fresh start to the life of your boat.

Radial, thermal and linear cracks

Radial cracks are like spiderwebs and generally occur on holes that have been welded shut before being filled. 

Thermal Cracks occur when part of the boat is left in the sun and warms up, which causes a temperature change in the rest of the boat. This can be prevented by putting a cover over any unused areas or moving it into the shade. If this has already occurred, there may be other filler damage so you should arrange for this to be repaired at the same time.

Linear cracks are divided into two categories: primary and secondary. 

  • A primary linear crack develops in the gel coat layer itself. These cracks tend to start in areas of higher stress, such as transition zones or simply at a point where there is a higher concentration of gel coat, but they may also occur randomly. 
  • Secondary linear cracks develop from the primary crack over a period of time due to flexing in these weak points.


Gel coat is susceptible to blistering.  A blister happens when the gel coat or resins begin to break down. Small cracks and stress raisers in your hull will cause the bubbles that appear in the blister. 

This is different from a blister that you have on your hand, which is caused by friction. Boat blisters, typically formed in high traffic areas, are caused by the sun’s ultraviolet rays hitting your boat and causing oxidation and degradation.

Keep your boat looking its best with professionally done repairs. With servicing available throughout Hampshire, BowToStern has extensive experience with GRP/gel coat repairs.
