Professional Underwater Boat and Marine Services
High Tide Dive Service provides dependable underwater maintenance, inspection, recovery, and specialized diving services for boat owners, marinas, boatyards, and marine contractors throughout Coastal North Carolina. From routine hull cleaning and zinc replacement to urgent line removal and complex underwater projects, every job is approached with careful planning, honest communication, and respect for your vessel.
Underwater Boat Maintenance Services
Routine underwater maintenance helps improve vessel performance, protect expensive equipment, and identify developing problems before they lead to costly repairs or an unexpected haul-out.
Underwater Hull Cleaning
Marine growth on a hull can reduce speed, increase fuel consumption, and place additional strain on the engine and running gear. High Tide Dive Service removes algae, barnacles, and other buildup from the hull and underwater components using methods appropriate for the vessel and its coating.
Hull cleaning may include:
- Hull surfaces
- Keels
- Trim tabs
- Thrusters
- Water intakes
- Transducers
- Other accessible underwater equipment
Zinc Anode Inspection and Replacement
Zinc anodes help protect propellers, shafts, rudders, and other submerged metal components from galvanic corrosion. High Tide inspects existing anodes, documents their condition, and replaces worn or missing anodes using the correct size and type for the vessel.
Propeller and Running Gear Services
Damage, marine growth, fishing line, or other debris around the propeller and running gear can cause vibration, reduced performance, and mechanical wear. High Tide inspects and services accessible underwater components to help identify and correct problems before they become more serious.
Services may include:
- Propeller cleaning and inspection
- Shaft inspection
- Rudder inspection
- Strut and bearing inspection
- Running gear cleaning
- Debris and fishing line removal
- Underwater documentation of visible damage
Underwater Inspections and Documentation
When something does not feel right with your boat, an underwater inspection can provide valuable information without immediately hauling the vessel out of the water.
Underwater Vessel Inspections
High Tide performs visual inspections following groundings, storms, collisions, unusual vibration, performance changes, or suspected underwater damage. Inspections can include the hull, propeller, shaft, rudder, trim tabs, thrusters, intakes, and other accessible components below the waterline.
An inspection can help determine whether the vessel appears safe to operate, requires additional evaluation, or should be hauled out for repairs.
Underwater Photography and Video
Underwater photos and video allow boat owners, mechanics, marinas, and contractors to see conditions that would otherwise remain hidden below the surface. Documentation may be used for maintenance planning, repair estimates, insurance discussions, pre-purchase evaluations, or confirmation that work has been completed.
Rope, Line, and Debris Removal
Entanglements can quickly turn into serious propulsion and safety problems. High Tide provides underwater removal services when rope, fishing line, crab pot line, netting, or other debris becomes wrapped around a propeller, shaft, rudder, or other submerged equipment.
Propeller and Shaft Line Removal
Wrapped line can damage seals, restrict movement, cause vibration, and place stress on the drivetrain. High Tide carefully evaluates the entanglement and removes accessible material using specialized underwater tools.
Underwater Hazard Removal
High Tide can remove certain underwater ropes, cables, debris, and obstructions that create hazards for vessels, docks, marinas, or waterfront properties. Each project is evaluated based on water conditions, access, visibility, current, depth, and the type of material involved.
Search and Recovery Services
Items lost in the water may still be recoverable when the approximate location is known, and conditions allow for a safe search.
Underwater Search and Recovery
High Tide provides organized underwater searches for anchors, tools, phones, jewelry, marine equipment, and other lost property. Search patterns are selected based on the location, bottom conditions, visibility, current, and information provided by the customer.
Recovery cannot be guaranteed, but a prompt response and accurate location information can significantly improve the likelihood of finding the item.
Equipment and Anchor Recovery
Lost anchors, boating equipment, and heavier objects may require additional planning, rigging, or lift equipment. High Tide evaluates the object’s estimated size, weight, depth, and location before determining the safest recovery approach.
Specialized Underwater Dive Services
Some projects do not fit neatly into a standard service category. High Tide provides experienced underwater support for unique marine challenges, inspections, maintenance needs, and project-specific work.
Underwater Cutting and Removal
High Tide can perform underwater cutting for certain ropes, lines, cables, netting, and removable obstructions. The scope of work is reviewed in advance to determine whether it can be completed safely with the available equipment and diving methods.
Hydro-Washing and Focused Cleaning
For projects requiring more concentrated cleaning, hydro-washing may be used on appropriate submerged surfaces and equipment. This service may be useful for selected marine growth removal, inspection preparation, and specialized maintenance projects.
Salvage Support
High Tide may assist with selected recovery and salvage-related projects when the scope, equipment needs, water conditions, and safety requirements are appropriate. Larger or more complex salvage operations may require coordination with additional contractors, lift equipment, or specialized commercial resources.
Service for Recreational and Commercial Vessels
High Tide Dive Service works on a wide range of recreational and commercial boats, including vessels commonly ranging from approximately 24 to 58 feet. Each request is reviewed individually because vessel design, marina access, water conditions, depth, current, and the type of work required can affect how the service is performed.
