The plastic in a feberglass hatch is ot smooth enough for a suction cup. Here we need need to use a small plastic plate #1542 that attaches with double sided tape. The same plate you can have on the dashboard in your car for a GPS. See #1542

Yes it will fit all shapes, round, square and rectangular. There will be a larger overlap in the corner on round hatches. Round hatches have a inner diameter of 500 mm. Choose 1310 for dark and 1410 for mosquito net.

Yes, with nets it’s no problem and with blinds you need to prolong the suction cup / magnet with a cord in the same way as the mosquito net on hatch / portlight.

Yes, but the hatch and suction cup must be clean. Old hatches often have some grease / dirt that needs to be cleaned with soap and water. If there is problem, clean both hatch and the suction cup. If the hatch and suction cup are clean it can sit for years. You may also use the magnet solution #9025. Magnets are included in all new package of mosquito nets / blinds.

The nets and blinds are universal. They are larger then opening “cut-out” for the hatches. They will fit all brands such as Lewmar, Rutgersons Marine, Bomar, Taylor made and many more.

Yes the hatches are the same on both motor and sailboats, so it’s not an issue.

It’s not a problem if the suction cup and the portlight is clean but to make sure we have included a security line that you have from the suction cup to one of the handles of the portlight.1435-Section-secured-portlight

You must use a blind with 2 suction cups(#1315 or #1320). For mosquito nets this is not a problem since the suction cup can sit on the side of the ventilation.

Open portlight (lets in air and make the boat dark)
1. Open the portlight.
2. Mount the suction cup or magnet according to instruction, on the blind.
3. Press the suction or the magnet (magnet and metal plate) to the window. Make sure the suction cup and window is clean for best result.
4. The blind will be on the outside of the portlight.
3. Tighten up the blind against the wall / portlight by folding the portlight window.
6. Use the security line and attach it to the knob on the portlight.

Closed portlight
1. Keep the hatch portlight.
2. Mount the suction cup or magnet according to instruction, on the blind.
3. Press the suction or the magnet (magnet and metal plate) to the hatch. Make sure the suction cup is clean for best result.
If you have a deep portlight you need to use a cord to prolong the suction cup / magnet.
To remove the net, don’t pull in the blind. First remove the suction cup or magnet with a finger.

The most common size on boats are ~500 x 500 mm (20″ x 20″). A regular size.  It’s large enough to exit out of also used as an emergency exit. Larger hatches are often much larger compared to the regular size. Boaters that are uncertain about their size have regular hatch to 99,99%. Our large nets / blinds will not fit super good on a regular hatch. We will be happy to exchange if you got the wrong sizes.

You measure the “cut out” size, the size of the hole the net / blind needs to cover. The net / blind must be larger than the “cut out” size.

By its nature, the Spiroll wraps around a line. This wrap can be pulled tighter around the line by grasping the outer edge and pulling. Basic electrical tape is all that is needed to keep the unit tightly wrapped in place and secured in position anywhere on a line.
