Installing a davit or gangway permanently alters the deck layout and the aesthetics of the stern. Before proceeding, consider the loads involved: a davit must lift the weight of the tender, the outboard engine, and any residual water. The material of choice remains AISI 316 stainless steel, which provides the resistance needed in a marine environment. An undersized structure risks dangerous flexing or structural damage to the fiberglass.
For gangways, the choice depends on use: folding or telescoping models offer versatility, while fixed versions are suited to simpler configurations. Always check the declared safe working load (SWL). Do not overlook the mounting: a pin-style attachment requires a reinforcing plate below deck to distribute stress correctly during passenger transit.
As the Nautiba technical team, we make sure every component arrives with the information needed for correct installation. We review your request to prevent incompatible purchases. If the selected model requires specific mounting hardware or supports, we let you know before the part arrives, so maintenance work is not held up.
Criteria for an Informed Choice
Choosing the right solution means preventing corrosion problems or mechanical failures. Follow these guidelines:
- Check the SWL rating: ensure the maximum weight exceeds the combined weight of the tender and engine.
- Verify the material: prefer AISI 316 for components constantly exposed to spray.
- Evaluate the mounting points: confirm that the stern structure can handle the dynamic load.
- Consider the stowed footprint: when folded, the gangway must not interfere with maneuvering.
How do I choose the correct load rating?
The rating must cover the weight of the tender and engine. Always calculate the maximum operating load with a safety margin, especially if you leave the tender hanging while underway.
Is it necessary to reinforce the transom?
Yes, an internal reinforcing plate in steel or marine-grade wood is often needed to distribute stress and prevent cracks in the fiberglass.
Why prefer AISI 316 stainless steel?
AISI 316 contains molybdenum, which significantly increases resistance to chloride corrosion, essential for external hardware in contact with a marine environment.
What if I am unsure about bracket compatibility?
Check the attachment dimensions and contact our technical support. We will review the datasheet to confirm whether the model suits your boat.
