Setup and Installation

Proper installation is crucial for the performance and watertight integrity of your Bomar hatch. It is recommended that installation be performed by a qualified marine technician.

Required Tools and Materials:

  • Drill
  • Appropriate drill bits
  • Marine sealant (e.g., P2000-81 tape as recommended by Bomar)
  • Fasteners (stainless steel, appropriate length for deck thickness)
  • Measuring tape and marking tools

Installation Steps:

  1. Prepare the Opening: Ensure the deck opening is clean, dry, and free of debris. The recommended hole cut-out dimension is 20 1/4” x 20 1/4”.
  2. Test Fit: Carefully place the hatch frame into the opening to verify fit. Ensure it sits flush with the deck surface.
  3. Apply Sealant: Apply a continuous bead of marine sealant (such as P2000-81 tape) around the underside of the hatch flange that will contact the deck. This creates a watertight seal.
  4. Position and Fasten: Carefully lower the hatch into the opening, aligning it as desired. Secure the hatch frame to the deck using appropriate stainless steel fasteners through the pre-drilled holes in the frame. Tighten fasteners evenly to compress the sealant, but do not overtighten.
  5. Clean Excess Sealant: Wipe away any excess sealant that squeezes out from under the flange immediately after fastening.
  6. Final Check: Open and close the hatch several times to ensure smooth operation. Verify that the tie-down dogs engage properly.

Operating Instructions

The Bomar Nibo Hatch is designed for ease of use and secure closure.

Opening the Hatch:

  1. Release Tie-Down Dogs: Rotate the quick-acting tie-down dogs located on the underside of the hatch lid to disengage them from the frame.
  2. Lift the Lid: Gently push the lid upwards. The support arms will assist in holding the hatch open.
  3. Vent Position (if applicable): For ventilation, the hatch can be secured in a partially open, locked vent position. Consult your specific model for this feature.

Closing the Hatch:

  1. Lower the Lid: Carefully pull the lid downwards until it rests flush with the frame.
  2. Engage Tie-Down Dogs: Rotate the quick-acting tie-down dogs to engage them securely with the frame. Ensure they are fully tightened to create a watertight seal.

Maintenance

Regular maintenance will extend the life and maintain the appearance of your Bomar Nibo Hatch.

  • Cleaning: Clean the acrylic lid and aluminum frame regularly with mild soap and fresh water. Avoid abrasive cleaners or solvents that can damage the acrylic or anodized finish.
  • Gasket Inspection: Periodically inspect the rubber gasket around the perimeter of the lid for signs of wear, cracking, or compression set. A damaged gasket can lead to leaks. Replace if necessary.
  • Hinge Lubrication: Apply a small amount of marine-grade lubricant to the hinges and tie-down dog mechanisms annually to ensure smooth operation and prevent corrosion.
  • Fastener Check: Annually check all mounting fasteners for tightness. Do not overtighten, as this can damage the deck or frame.
  • Acrylic Care: To prevent scratches, avoid wiping the acrylic when dry. For stubborn stains, use a plastic-specific cleaner.
