Top Diving & Underwater Services Pros

Underwater hull cleaning typically costs between $150 and $600 for most recreational boats, depending on vessel size, amount of marine growth, and the diver's location. Larger yachts or heavily fouled hulls may cost more. Getting an in-water cleaning done regularly is far less expensive than a full haul-out and bottom paint job.

Most boat owners in warmer coastal waters benefit from hull cleaning every 4 to 8 weeks during peak boating season, as marine growth accumulates quickly in these environments. In cooler or less active waters, every 2 to 3 months may be sufficient. A commercial diver can assess your specific growth rate and recommend a maintenance schedule.

Yes, replacing zinc anodes underwater is one of the most common in-water dive services. A certified commercial diver can remove corroded zincs and install new ones on hulls, shafts, props, and rudders without any need to haul the vessel. This service is typically fast and affordable compared to scheduling a haul-out.

Commercial marine divers generally charge between $75 and $200 per hour depending on location, water conditions, and the complexity of the work. Minimum call-out fees often apply, typically covering the first hour or two. Specialized work such as underwater welding, salvage, or structural inspection may be priced as a flat project rate.

An underwater hull inspection typically covers the condition of the bottom paint, hull integrity for blistering or impact damage, propeller and shaft alignment, zinc anode condition, through-hull fittings, rudder, and keel hardware. The diver will often provide a written report or photo documentation of findings. This type of inspection is especially valuable when purchasing a used vessel or after a grounding incident.

Yes, line, rope, and net removal from propellers and shafts is a very common emergency dive service. A commercial diver can respond quickly, assess the situation, and safely remove the obstruction without damaging the shaft seal. This service can often be completed in under an hour depending on the severity of the entanglement.

Commercial divers are frequently used during dock installation and maintenance projects to assist with pile placement, underwater fastening, inspection of existing piling condition, and post-installation assessment. Divers ensure that underwater components are properly set and structurally sound, which is essential for dock safety and longevity. Marina operators and waterfront property owners regularly rely on dive contractors for this work.

Lost item and anchor retrieval is a standard commercial dive service. As long as the approximate location is known and depth is within safe working range, a diver can typically recover anchors, chains, outboard motors, and other sunken items. Recovery success depends on visibility, bottom conditions, and the weight of the object, but many recoveries are completed in a single dive session.

When done correctly, underwater hull cleaning by a trained diver is safe for ablative and hard antifouling bottom paint. Professional divers use soft brushes or pads matched to the paint type to remove marine growth without stripping the coating. Aggressive scrubbing or using the wrong tool can damage paint, so it is important to hire a diver experienced specifically in hull cleaning.
