Managing boarding on a generously sized boat requires reliable equipment that stands up to the corrosive action of salt. A servo-assisted telescoping gangway is not just a convenience accessory but a structural element that must integrate with the boat's electrical or hydraulic system. When evaluating a model, pay close attention to the material composition: the use of anodized aluminum alloy structures or AISI 316 stainless steel is essential to prevent early oxidation that would compromise the sliding of the telescoping sections.
Walkway stability is another critical factor. A non-slip walking surface, often in synthetic teak or treated wood slats, must provide consistent grip even with wet footwear. Always check the declared safe working load (SWL) relative to the distributed load, especially if you expect heavy use with guests on board. Keep in mind that the drive mechanism must be protected from external elements, with an adequate IP protection rating for cockpit installation where spray exposure is common.
The technical support we offer at Nautiba is specifically designed to help you avoid common mistakes, such as incorrectly sizing the system for the available cockpit space or incompatibility with onboard voltage. Before proceeding, it is necessary to verify the stowed footprint and the total extended length. Analyzing the opening mechanism and mounting points will help you determine whether the gangway aligns correctly with the transom, ensuring a safe angle of inclination at both high and low tide.
A proper installation demands meticulous attention to electrical connections. Using cables of adequate cross-section for the run length and correctly sized circuit breakers is essential to avoid voltage drops. Make sure pins and hinges are regularly inspected and lubricated with specific marine greases that do not attract dust and resist washout from seawater. If you have difficulty understanding the mounting specifications, our technical team can review the engineering drawings to help you choose the most suitable model.
Selection and Installation Tips
- Always check the space required to stow the system when not in use.
- Make sure the maximum load rating (SWL) is consistent with the expected load during boarding.
- Confirm that the motor voltage (12V or 24V) matches the onboard electrical system exactly.
- Verify the type of transom mounting, assessing whether a custom bracket is required.
- Periodically inspect correct operation of the limit switches to avoid unnecessary strain on the gearmotor.
How do I determine the required maximum load rating?
The maximum load rating (SWL) must be calculated by considering the average weight of passengers and any equipment being moved. It is prudent to slightly oversize the working load to ensure structural stability during natural deflection under load.
Which materials offer the best corrosion resistance?
AISI 316 stainless steel is the nautical standard for corrosion resistance thanks to the addition of molybdenum, which counters the action of chlorides. Anodized aluminum alloy is also a valid option, provided the anodizing layer is thick and free of scratches that could trigger galvanic corrosion.
Can the gangway be installed on any vessel?
Not all transoms are structurally adequate. It is necessary to verify the presence of a reinforced mounting surface in fiberglass or steel to withstand dynamic loads. Without a proper anchor point, the risk is damaging the hull during use.
What to do if the gangway makes noise during operation?
Unusual noises often indicate a lack of lubrication in the telescoping sections or misalignment of the sliding pins. A thorough cleaning followed by the application of silicone lubricant or water-repellent nautical grease typically resolves the problem.
