Boat Door Accessories

On board, doors and hatches are subject to constant vibration and the corrosive action of salt water. A hinge that squeaks or a latch that no longer engages are not merely annoyances - they are signs of deterioration that can compromise the watertight seal and safety while underway. Replacing these elements requires technical knowledge to select components that provide structural resistance adequate for the intended working load.

At Nautiba we work to prevent errors before the item ships. We know all too well what it means to receive a replacement part that is off by a few millimeters or has the wrong thread pitch. Before proceeding, we verify the technical compatibility of the part. Our pre-sales support analyzes drawings and measurements, ensuring that the component you choose is suited to your vessel model and your actual operating conditions.

When choosing accessories, the distinction between AISI 304 and AISI 316 is critical. The addition of molybdenum in grade 316 stainless steel allows the metal to resist chloride attack over time. Relying on properly made components means you will not have to revisit the work after just a few seasons. Our selection reflects this practical approach, favoring components tested for the boater who wants an efficient, reliable vessel.

Selection criteria for onboard hardware

Before purchasing latches or hinges, consider a few essential technical parameters for a lasting installation:

  • Verify the material: prefer AISI 316 stainless steel for external components or those subject to salt-laden humidity.
  • Check the dimensions: do not stop at the hole diameter - verify the screw spacing and the inset depth.
  • Assess the load: for heavy hatches, make sure the hinge has an adequate load rating.
  • Inspect the finish: a mirror-polished surface is easier to clean and retains less salt.

How do I choose the right hinge for the companionway?

The choice depends on the weight of the door and its location. AISI 316 is essential for external applications, while AISI 304 can be considered for protected interior use. Always check the stated load capacity.

What if I cannot find the exact replacement part dimensions?

If the original component is no longer available, measure the spacing of the existing holes in the gelcoat. It is often better to fill the old holes with epoxy resin and redrill to align the new fitting correctly.

Are interior door locks the same as exterior ones?

No, exterior locks require greater protection against water and salt. Always verify that the IP protection rating is appropriate for the exposure the component will face on the cabin top or in the cockpit.
