Record boat make, model, year, beam, hull type, and loaded operating weight
Use loaded operating weight when available rather than dry-hull weight alone. Shoreline does not select engineering capacity.
Boat lift project readiness
Before You Call a Boat Lift Installer
A useful lift proposal starts with the real boat, the dock and support structure, and what the property is already authorized to have.
11 lift-readiness checksNo capacity guessingPrint or share with a marina / boat dealer
Use it this way: Gather the inputs an installer needs to understand the project. Shoreline deliberately does not calculate engineering capacity or treat a homeowner-entered weight as a final equipment selection.
Use the Boat Lift Planner →Boat
Bring the actual vessel information
A lift should be planned around the real boat and site, not a round capacity guess.
Tell the installer if you expect to change boats soon
A near-term larger or heavier vessel can materially change the equipment and site discussion.
Photograph the lift, dock, support pilings, controls, and access
For repairs, include visible corrosion, cables, motors, pulleys, bunks, and the way the lift connects to the dock.
Site
Confirm the lift is really a lift-only project
A lift problem can actually be a dock, piling, electrical, or permitting problem.
Note any dock movement, damaged framing, or questionable lift-support pilings
If the surrounding structure is also compromised, treat it as a combined dock-and-lift evaluation rather than equipment replacement alone.
Identify the electrical scope
Wet-location electrical work should be handled by qualified professionals and may require local permits/inspection. Clarify who owns that work.
Check creek/site constraints before assuming a new lift can be added
SCDES notes that boat lifts are not allowed on creeks under 20 feet wide, including limited cases where a small dock may otherwise qualify.
SCDES Critical Area FAQ ↗Find the current dock/lift permit if possible
A new lift, replacement, and repair can have different permit treatment depending on what was previously authorized.
Proposal
Make equipment, structure, electrical, and permit responsibility explicit
The installer quote should be understandable even if another professional handles part of the work.
Ask what complete system is being priced
Clarify lift type, major components, bunks, controls, piling/support work, access/catwalk, and exclusions.
Ask how the installer selected the proposed capacity/configuration
The answer should tie back to the actual vessel, loading, hull geometry, site, and manufacturer/engineering requirements—not a homeowner guess.
Ask who handles coastal and local approvals
SCDES specifically treats boat lifts as additions to dock structures requiring approval; the exact lane depends on the existing authorization and proposed change.
SCDES Minor Activities ↗Get equipment and workmanship warranty terms in writing
Know what is covered, who services the system, and what maintenance is expected after installation.
When the checklist surfaces a real project
Turn these inputs into a structured lift project.
Shoreline can organize the boat, dock, site, and permit facts before applying contractor-fit rules.
