What happens when a boat sinks and what to do about it
A sunken boat becomes a more expensive problem the longer it sits. Fuel and oil start leaching into the water within hours. A fiberglass hull that stays submerged begins absorbing water and degrading. If the vessel is at a marina or in a shared waterway, the liability clock starts ticking immediately — for you, not for whoever owns the dock or the water around it.
Captain Tom's Boat Removal responds to sunken vessel situations with the equipment to recover the boat and the experience to do it without causing additional damage to the hull, the dock structure, or the surrounding environment. We've recovered boats from shallow slips, deeper channel water, lake bottoms, and everything in between.
How sunken boat recovery works
- Environmental containment first — The moment we're on scene, we deploy containment booms around the vessel to capture any fuel or fluid already in the water. This is always step one, before any lifting equipment touches the boat.
- Condition assessment — We assess the boat's position, depth, and structural condition before attempting a lift. A boat that's resting on a soft bottom requires a different approach than one that's wedged against pilings or buried in sediment.
- Recovery operation — Depending on the situation, we use lift bags, salvage pumps, rigging, or a combination of all three to bring the boat to the surface in a controlled way. Uncontrolled refloating causes further hull damage and spreads contamination.
- Haul-out and transport — Once the vessel is on the surface and stable, we haul it out of the water and transport it to a facility for assessment, salvage of usable parts, and proper disposal.
- Documentation for insurance — We provide full written and photographic documentation of the recovery — scene condition on arrival, containment actions, recovery method, and condition of the vessel post-recovery. This is what your insurance carrier needs to process a claim.
Who calls us for sunken boat removal
We work with individual boat owners who wake up to find their vessel on the bottom of their slip. We work with marina operators dealing with a sunken boat that's blocking a fairway or creating a liability. We work with insurance adjusters who need a documented, professional recovery on record. And we work with municipalities and waterway authorities dealing with derelict sunken vessels that have been abandoned.
In every case, the priority is the same: get to the scene fast, contain the environmental threat, recover the vessel safely, and document everything.
Frequently Asked Questions
Most marine insurance policies with salvage coverage will cover sunken vessel recovery. We provide the documentation your insurer needs. If you're unsure about your coverage, call your carrier while we're en route — don't wait on the insurance question before calling us.
We'll give you an honest assessment on-site. Some sunken boats recover fine once they're out of the water. Others, particularly those that sat submerged for a long time, are total losses. Either way, the vessel still needs to come up — a sunken boat doesn't become legal to abandon just because it's underwater.
Long-submerged vessels present additional challenges — sediment accumulation, marine growth, and hull degradation — but they're still recoverable in most cases. Call us with the details and we'll tell you what's involved.
The registered owner remains legally responsible for a sunken vessel and any environmental damage it causes, regardless of how it sank. If you've been notified by a marina or harbormaster, act quickly — fines for unaddressed sunken vessels can accumulate fast.
