Fibreglass boat restoration case study: Cove
A boat restoration case study. Cove was stripped back and rebuilt: new floor, teak deck, new engine. The transom held the real lesson.
A fibreglass boat restoration means taking a tired hull back to sound material, fixing what is underneath, and putting it back together better than it was. Joe did exactly that on Cove. It now has a teak deck and the name Cove, and it has its own highlight on our Instagram. It did not look like that when it arrived.
Cove arrived at the factory for a full restoration in November 2024. Most of the work happened in the workshop through the middle of 2025, some of it on what Joe called the night shift. This is what the job involved, and what it taught us about fixing boats.
Stripped back
The first job on any restoration is finding out what you are actually working with. Seats, fittings and the old floor came out, back to the hull, with the boat sitting on its trailer in the factory.
It is the least glamorous stage and the most important one. Fibreglass hides things. A floor can feel solid at the helm and be soft a metre further back. You only know once it is open.
A new floor
With the hull open, Joe cut and fitted a new floor. His stories from that stage are mostly a circular saw and sheets of ply, captioned “Getting those perfect cuts”, and then the result at dusk: “New floor lets goo!”
The floor of a small boat does real work. It ties the sides of the hull together and it is what you stand on when the boat slams off a wave, so it has to be cut to fit properly and sealed properly. New seats arrived next.
The teak deck
Then came the part that makes the boat look the way it does. Joe laid a deck in Indonesian teak, strip by strip, each one measured, cut and fitted. The story from that stage is a workshop buried in dust with the caption “Aftermath of Indonesian Teak”.
Sanding ran through the whole job. One day of it got a tick on the story and this:
“That feeling never gets old!”
The deck seams were caulked later, taped off seam by seam, and the timber was oiled by hand in more than one round. Joe was honest about that part too: “Round 2 of the oiling process this is for sure very time-consuming and a process of love but God does it look good when it’s done.”
Engine day and launch
The new engine went on at the boatyard (“Big day! Installation of the new engine.”), and in August 2025 the boat went in the water.
The lesson was in the transom
This is the part that matters if you own a boat.
In December 2025, after a few months of use, Joe went back to the engine mount. The outboard hangs off a pod at the stern. He fitted new backing plates behind its bolts and explained why:
“New backing plates installed, this engine was putting a load of stress on the old pod.”
The next frame shows the old arrangement, with the bolt going, in his words, “straight through the fiberglass”.
Fibreglass is strong across a wide area and weak at a point. A bolt through a laminate with only a small washer behind it puts the thrust of the engine, and every slam of the hull, through a few square centimetres. Over time the glass around the hole can crush and crack. A backing plate spreads that load across a much bigger patch of the laminate.
It is the same idea as the reinforcement under a fin box or a leash plug on a surfboard. Wherever a hard fitting meets a composite skin, the load has to be spread.
What it changed for us
Doing every part of a restoration on a boat changes how you quote and how you explain the work.
- We know what is behind the panel. Having taken a boat back to the hull and put it together again, it is easier to judge from a photo what a crack is likely to be sitting on.
- We know where the hours go. Sanding, fairing and finishing take the time, which is why marine work is quoted on the damage and not by the metre.
- We look at fittings first. Rudders, engine mounts and cleats are where the loads are, so they are where trouble often starts.
A customer’s trailer sailer came through the factory in October 2025, with a worn rudder fitting and a hole in the hull that had to be found from the inside. That job is written up in our fibreglass boat repair guide.
If your boat needs work
The boat price sheet in the workshop runs from small gelcoat chips to floor replacement, transom repairs and full restorations. Every job is quoted free before anything starts. Send photos, tell us the make and what happened, and you will get a straight answer on what it needs.
Details are on the boat repairs page, with Jet Skis on their own page and gelcoat refinishing on the paint and respray page.
