Mobile Bay Fiberglass Theodore has more boats in the water per square mile than anywhere else on the western shore of Mobile Bay. Dog River alone carries three full-service marinas, Dog River Marina and Boat Works, Turner Marine and Grand Mariner Marina, and a few miles south the Fowl River waterfront adds sailboats, bay boats and offshore hulls tied up behind homes and camps. Most of these boats never leave the water. They sit in brackish, warm slips through a Gulf Coast summer, and that is exactly the environment that breaks down fiberglass over time.
The damage we see in Theodore follows a pattern. Gelcoat on uncovered boats chalks out fast under the Alabama sun, especially on dark hull sides and cockpit soles. Crowded slip rows on Dog River produce dock rash, scraped rub rails, crushed corners and spider cracks around cleats and stanchion bases. Older sailboats and cruisers that have lived in the river for a decade or more show hull blisters below the waterline, and outboard boats that spend the season on a lift with the plug in develop wet transom cores you can find with nothing more than a knuckle and a mallet. None of this fixes itself, and all of it gets more expensive the longer it soaks.
We come to you. Fiberglass and gelcoat work at your slip, on your lift or in your driveway anywhere in the 36582 area, from the Dog River bridge down to the mouth of Fowl River. Most gelcoat and dock rash jobs happen in a single visit. Structural work, soft transoms, wet stringers and cracked hulls, gets a written estimate first so you know the number before we ever pull a grinder out of the truck. Call (251) 220-4157 and tell us where the boat sits, and if you can text a few photos first, most Theodore jobs get a firm number the same day.
What Dog River does to a hull
Dog River boats live in brackish water, which is a little easier on bottom paint than the open bay, but the trade is sun. A lot of Theodore slips have no covers, and south-facing gelcoat there chalks noticeably faster than the same boat kept under a shed on Fowl River. If your hull side leaves white powder on your hand, it is time to cut and buff before the gelcoat goes too thin to save.

Theodore fiberglass questions
Can you fix my boat in the water at Dog River Marina, or does it have to come out?
Gelcoat, dock rash and most deck work can be done in the slip, and we handle jobs at Dog River Marina, Turner Marine and Grand Mariner all season. Anything below the waterline, blister repair, keel damage or through-hull glass work, needs the boat hauled or on a lift, and the yards on Dog River can short-haul it the same week in most cases.
What does dock rash repair cost on a boat kept in Theodore?
Minor gelcoat chips and scratches run $150 to $500 depending on color match and how many spots there are. If the rash has gone through the gelcoat into laminate, a hull section repair runs $500 to $1,500. We quote off photos first so you know which side of that line you're on.
My transom flexes when I trim the motor. Is that fixable or is the boat done?
It's fixable, and it's common on Fowl River boats that have lived on a lift with water sitting against the transom for years. A full transom replacement runs $2,500 to $8,000 depending on the boat and whether we can do it from the inside. The boat is not done, but don't keep running a soft transom, because the motor bolts are working in wet wood.
How long does a typical repair take? I don't want to lose the season.
Cosmetic work is usually one visit, a day or less. Hull section repairs run two to four days with cure time between laminating and fairing. Transoms and stringer jobs take one to three weeks. Summer is our busy stretch in Theodore, so call early, and small jobs can often slot in within the week.
Do you match gelcoat color, or will the repair show?
We custom-tint gelcoat on site to match your hull, including aged and sun-faded finishes, which matters because a ten-year-old white hull on Dog River is not the same white it left the factory with. On most repairs you will have to hunt for the spot to find it.
