Trimport / Coastline Fitting & Adjustment Instructions
(To be retained in owners manual for future reference)
Trimport and Coastline hatches are for use on deck and coachroof of yachts in accordance with
ISO/DIS 12216.2(E), DESIGN CAT "A", AREAS II, III and IV. Modification of the hatch by the fitting
of vents etc. will invalidate the compliance with this standard.
Fitting Instructions
Trimport and Coastline hatches should be fitted to a flat surface with a maximum tolerance of +/- 1mm
and a deck / hull thickness of 15-61mm. Check that all fastening will be clear of deck moulding radii
etc. Allow clearance for lid opening.
Do not open and close the hatch more than necessaryuntil the lower frame is securely mounted.
Mark the deck with a pencil around the outside edge of the lower frame flange.
It is essential that the lower frame is placed squarely on the deck opening.
When fitting a number of hatches it is advisable to prepare a template.
Cut out deck along pencil line using a suitable saw.
Where the deck is of composite construction, it is recommended that the exposed laminate be sealed
with the appropriate material prior to fitting the hatch. Openings cut in metal decks should have all
burrs and sharp edges removed.
Hatches should not be considered as stiffening members and it is recommended that the deck be
adequately stiffened to prevent distortion during heavy weather.
Re-check the frame on aperture and then apply bedding compound to the channel in lower frame.
Bedding compound must have good adhesive qualities (eg. silicone sealant), be a suitable grade for
marine sealing applications, of 3mm minimum thickness and compressible to allow the lower frame to
be pulled down in contact with the deck by the securing screws.
Position lower frame over hole and drill two fixing screw holes in opposite corners. Insert appropriate
stainless steel fasteners.(see below).
Deck type
Wood M5 through bolts or marine grade wood screws.
GRP/Steel/Al Alloy M5 through bolts or machine screws into suitable tapped plates.
Fixing Sizes M5, 10UNC, 2BA, 3/16", Wood screws (min. length 40mm).
Drill remainder of holes and fasten down from the centre working out to the edges. Clean off surplus
sealant.
Once installed check for correct operation of the hatch lid, ie. closing/locking, even pressure of seal
etc.
