What are the benefits of extending a swim platform on my boat?

A swim platform extension provides more usable space for swimming, boarding, relaxing, and water sports. It improves safety when getting in and out of the water and adds comfort and value to your boat.

Can you repair cracks or soft spots on an existing swim platform?

Yes, we repair cracks, delamination, soft spots, and structural damage. Our repairs restore strength, safety, and appearance using marine-grade materials designed for long-term durability.

What materials do you use for swim platform extensions?

We use marine-grade fiberglass, composite cores, aluminum frameworks, and non-slip surfaces such as EVA foam or marine decking. Materials are selected based on your boat type, weight capacity, and usage.

Is a swim platform extension safe for my boat’s transom?

Yes, when properly engineered and installed. We inspect the transom structure, reinforce mounting points if needed, and ensure the extension is safely supported without stressing the hull.

Can you customize the size and shape of the swim platform?

Absolutely. We design custom swim platform extensions to match your boat’s layout, width, and intended use. Custom options include ladders, handrails, non-slip decking, and integrated steps.

How long does a swim platform repair or extension take?

Minor repairs can often be completed within 1–2 days. Custom extensions or structural repairs typically take several days depending on complexity, materials, and curing time.

Do you provide warranty on swim platform repairs and extensions?

Yes, our workmanship is covered by a service warranty, and all materials used come with manufacturer warranties when applicable. Full documentation is provided for your records and future resale value.

About this service

Upgrade Your Stern

Waterfront
Real Estate.

The swim platform is where the fun happens. We handle swim platform repair after impact damage and fabricate seamless extensions to expand your deck space.

Impact Repair

Backed into a pylon? Dinghy hit the stern? We repair crushed corners, cracks, and delamination, restoring structural integrity and matching the gelcoat.

Extensions

We fabricate custom fiberglass swim step extensions that bolt onto your existing hull, adding 18-30 inches of usable space for tenders, jet skis, or lounging.

Surface Refinish

Upgrade the look with a new factory-style non-skid pattern, or let us install marine-grade soft foam decking (EVA) or real teak.

Fabrication & Repair.

From custom molds to seamless finishing.

Template

For a swim platform extension, we create a precise template of your transom curve to ensure a factory-tight fit.

Layup

We build the platform using high-density foam cores and biaxial fiberglass for maximum strength without heavy weight.

Mounting

We utilize heavy-duty 316 stainless steel brackets and through-bolts sealed with marine adhesive for a permanent bond.

Finish

The final surface is gelcoated, color-matched, and finished with non-skid to match your boat's existing deck.

Seamless Integration.

Common Questions

Is the extension strong enough to stand on?

Absolutely. Our custom swim platforms are structural. They are designed to support multiple people, heavy coolers, and normal boarding activity.

Can you match the non-skid pattern?

Yes. We take molds of your boat's existing diamond or stipple pattern and replicate it on the repair or extension area.

Marine Refinish Options for Your Swim Platform

Once a platform is repaired or extended, the surface gives it its finished look. A marine refinish on a swim platform has to stand up to sun, salt and constant foot traffic, so we offer three directions: a new factory-style non-skid pattern in color-matched gelcoat, marine-grade soft EVA foam decking, or real teak.

If you want the repair to blend in, we take a mold of your boat's existing diamond or stipple non-skid and replicate it on the new area. When you request a quote, send photos of the platform and any damage, mention how you plan to use the space (boarding, swimming, lounging, or carrying a tender or jet ski), and tell us which finish you are leaning toward.

Swim Platform Fabrication in Long Beach

Swim platform work is marine fabrication as much as repair: a template of your transom, a fiberglass layup over a high-density core, 316 stainless brackets and a color-matched gelcoat finish. The same steps apply whether we are rebuilding a cracked corner or adding a full extension to a boat in Long Beach or a nearby harbor.
