HATCH & PORTLIGHT PRODUCT MARKING & DATE CODING
All Lewmar Hatches and Portlights (except old Standard) produced since October 1997 have had
identification information stamped on the acrylic. On Portlights and Fixedlights the information is under
the αβχδ branding. On hatches the information is between the right hand handle and the edge of the
acrylic.
The information is:1) Range Name & Hatch Size
For Hatches; Ocean, Coastline, Trimport, Trimline or Concept
For Portlights; Standard (New Standard only), Atlantic, Ocean or ASTAR (Hallberg Rassy only)

A number in the form "399SSXR" for example 3996003 where:SS is the hatch size, in the example Size 60
X is the acrylic colour as per Table X in the spares book, in the example 0 for grey
R is the Range, 3 is Low Profile, as in the example, and 2 is Medium Profile
On Mark 2 Low & Medium Profile hatches the number is preceded by and “A” for example
“A3996002”
Or
A number in the form "300XXX" for example 300380. This is the first 6 digits of a hatch or
portlight custom product part number, in this case it would be 300380000

Trimline Hatch Fitting & Adjustment Instructions
(To be retained in owners manual for future reference)

Trimline hatches are for use on all craft types 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

Trimline 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 fastenings will be clear of deck moulding radii
etc. Allow clearance for lid opening.

Mark the deck with a pencil around the outside edge of the lower frame flange.
It is essential that the lower frame is placed square 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
GRP/Steel/Al Alloy
Fixing Sizes

M5 through bolts or marine grade wood screws.
M5 through bolts or machine screws into suitable tapped plates.
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.
Please Turn Over

User Notes
Opening of the hatch beyond the limit of the stays for maintenance etc. is possible by removing
the rubber bung stop. Gently lever the bung stop out. Supporting the lid, disengage the stay from
the lower frame and lay the lid back to approximately 145 degrees, until the upper frame is resting
on the deck.
During normal usage, the stays should remain engaged at all times.
Do not force the lid back or apply pressure as damage will occur to the hatch.

The locking ventilation position is used by closing the handles into the rebate in the lower frame.
Care should be taken not to stand on or load the hatch lid in this position, as damage could occur
to the handle or catch block.

Always wash the hatch with soap, water and a soft cloth.

Never use abrasive or solvent cleaners on the acrylic lid, as this may at a later date damage the
acrylic.

To avoid risk of injury care should be taken to keep hands and limbs clear of stay and lid pinch
zones while operating and adjusting the hatch.

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).

User Notes
Small "vent" hatches are restricted to 90 degree opening and should not be forced beyond their "stop"
position, as damage to the lever mechanism may occur. Larger hatches are not self supporting
beyond the vertical position and will fall fully open if unrestrained.

The locking ventilation position is used by closing the handles into the catch block centre slot. Care
should be taken not to stand on or load the hatch lid in this position, as damage could occur to the
handle or catch block.

Always wash the hatch with soap, water and a soft cloth.

Never use abrasive or solvent cleaners on the acrylic lid, as this may at a later date damage the acrylic.

To avoid risk of injury care should be taken to keep hands and limbs clear of lever and lid pinch zones
while operating and adjusting the hatch.

Friction lever adjustment
The friction lever units installed are pre-set when manufactured to give correct positioning with a
minimum opening load. It may be necessary occasionally to adjust the lever setting to correct the
operation of the hatch.
Adjustment is made by means of the socket head screws on either side of the lever assembly.
Using a 4mm (5/32") hexagon key, turn the adjusting screw approximately 1/8th of a turn in a
clockwise direction to increase the positioning force. This is most easily carried out in the fully open
or closed positions.
Do not over tighten the adjusting screws
On hatches with multiple lever units, care must be taken to adjust all levers to a similar
loading.

Open the hatch and check for correct operation.
Re-adjust if necessary until the desired operation is achieved.
Lubricants should not be used on the friction lever assemblies as this will adversely affect the
function of the units.

Concept Hatch Fitting & Adjustment Instructions
(To be retained in owners manual for future reference)

Concept hatches are for use on power craft in accordance with ISO/DIS 12216.2(E), DESIGN
CAT "A", AREAS II. Modification of the hatch by the fitting of vents etc. will invalidate the
compliance with thyis standard.
Fitting Instructions
Concept hatches should be fitted to a flat surface with a maximum tolerance of +/- 1mm and a
deck / hull thickness of 20-40mm Check that all fastening will be clear of deck moulding radii etc.
Allow clearance for lid opening.

Mark the deck with a pencil around the outside edge of the frame flange.
It is essential that the frame is a snug fit and placed squarely on the deck opening.
When fitting a number of hatches it is advisable to prepare a template.

seal etc.
Page 1 of 2 - Next Page

User Notes
Concept hatches are restricted to 85 degree opening and should not be forced beyond their
"stop" position, as damage to the linkage mechanism may occur.
Do not attempt to force the hatch closed or open when levers are locked as damage to the
linkage mechanism will occur.

If the hatch is accidentally closed with the levers in the closed position, the shear pin between the
small straight lever and the moulding will fail. The hatch can still be opened and closed but no
positioning is possible. Remove the broken parts and replace to rectify.

To adjust the lid opening position, support the lid whilst moving the locking levers to the unlocked
position. Position the lid, ensuring that the mechanism is correctly aligned when re-locking the
levers. This can be readily felt by moving the lid slightly.
Locking levers should remain in the unlocked position when the hatch is closed to prevent
accidental damage when opening.

The ventilation position is used by closing the handles into the rebate in the lower frame. Care
should be taken not to stand on or load the hatch lid in this position, as damage could occur to
the handle or window assembly.
Do not lock the levers in the ventilation position.

The hatch must always be closed when the boat is in motion to prevent accidental damage.

Where used, the flyscreen is fitted by using the sewn on tabs to stretch it across the corners of
the trim. Ensure that the elasticated bead is correctly located into the frame lip.
No adjustment to the hinge mechanism should be necessary during normal usage, however, if
the operation of the locking levers becomes excessively stiff, the centre screw may be adjusted
taking care to remove all free play.

Always wash the hatch with soap, water and a soft cloth.
Never use abrasive or solvent cleaners on the acrylic lid, as this may at a later date damage the
acrylic.
To avoid risk of injury care should be taken to keep hands and limbs clear of linkage and lid pinch
zones while operating and adjusting the hatch.

HATCH RETRO FIT LOCK & KEY FITTING INSTRUCTIONS
NOTES
• This kit does not fit Size 6 Hatches [882 x 882mm (34¾ x 34¾”) overall]
• These instructions are for square and rectangular hatches only.
• When drilling use water as a lubricant and control the drill speed to prevent the acrylic over
heating.
• When making the 20mm (¾”) hole, drill or cut in from both sides, this will prevent the acrylic
from chipping when the drill / hole saw breaks through.
• Fit the lock first, then confirm the position of the catch block which should be fitted second.
TOOLS REQUIRED
• 20mm (¾”) drill or hole saw
• 5mm (3/16”) drill bit
• variable speed drill

•
•
•

masking tape
rivet gun
12mm and 24mm (or adjustable) spanner

INSTRUCTIONS
1. Using the drawings over, confirm which type of hatch is to be modified.
2. On the outside of the hatch, apply masking tape in area where hole is to be drilled and mark the
centre of the hole using the dimension given in the drawings over.
3. Leave the masking tape in place to stop the drill bit slipping and drill a pilot hole.
4. Using water as a lubricant and controlling the drill speed to prevent overheating, use the pilot hole
as a guide to drill a 20mm (¾”) hole ½ way through the acrylic.
5. Complete drilling the hole from the other face of the acrylic to prevent chipping when the drill
breaks through.
6. Apply masking tape to the inside of the hatch in the area where the 5mm (3/16”) hole is to be
drilled. Mark the centre of the hole using the dimension shown in the drawing below. The hole
should be towards the edge of the hatch. Apply a small piece of masking tape 3mm (1/8”) from the
end of the 5mm (3/16”) drill bit to mark the drilling depth required and drill the hole to this depth.
7. Fit the lock assembly as shown in the drawings below, note that some hatches will require the
spacer. Ensure that the anti-rotation washer is correctly engaged before tightening the lock nut to
avoid acrylic damage.
8. The kit is supplied with two types of Catch Blocks, one for Ocean and Coastline hatches and one
for Low and Medium Profile hatches. Confirm which type of Catch Block is already fitted to the
hatch for the handles. The lock will require the same catch block fitted the same way up.
9. Apply masking tape to the lower frame in the area where the Catch Block is to be fitted. Close the
hatch and, with the handles engaged, establish the best position for the lock’s Catch Block. Mark
the hole centres on the masking tape.
10. Using the masking tape to prevent the drill from slipping, drill the holes for the catch block rivets
using a 5mm (3/16”) drill bit. Rivet the catch block in place.
