Hatch - Pop Top - Profile Rails

Hatch - Pop Top - Profile Rails
A$15.00

These rails are designed to be used in conjunction witht either the 735mm or 935mm Hatch End Kits.

Whilst we provide coprehensive instructions, This hatch project does require some knowledge of fiberglassing and filleting techniques. It also requires some small additional harware items which must be purchased seperately to complete the job.

We designed this hatch for the Trimaran. It has a large opening, being, 800mm (W) x 900mm (L). The idea is to purchase either the 935mm or 735mm wide hatch end kit and as many hatch profile rails as you need to suit the length. The 735mm kit, will cover a hatch opening width of 600mm. Custom sizes also available.

For example, If you were to use six of 300mm hatch profile rails and two 735mm hatch end kits, your overall size would be 735mm wide x 940mm long and the combined weight would be just over 1Kg before the glass layers and 4mm plywood top or cover.

Hatch profile rails come in lengths of 300mm, 200mm and 100mm and can be mix and matched. This will allow you to set a custom length depending on your requirements.

We do provide instructions on how to complete your hatch project and you will need to provide the following items on top of the 3D hatch cores.

  • 4mm Marine plywood/foam for top or cover, cut to your custom size.
  • 25mm x 10mm alloy rectangular tube to length of hatch(Bunnings)
  • 100mm Fibreglass tape 
  • epoxy resin

On the underside of the hatch profile rails is a hole which is designed to receive a short alloy pole. Same on the Cabin Top Hatch Profile. Four poles in position raises the hatch to the length of the pole and can be varied to suit making a simple to use pop top system, hatch legs are simply stored below when not raised.

This hatch can also be tilted. the 300mm pivot Profile rail has a 20mm hole in the vertical surface. This is designed to be filled with epoxy and then drilled to form the pivot at the back of the hatch. This allows you to lift the front of the hatch only, and again the front is supported by 20mm poles.

On my boat I wanted a 935mm (W) x 940mm (D) hatch with pop top and pivot.

1 x 935mm Hatch End Kit

4 x 300mm Hatch Profile Rail with Pop Top Hole

2 x 300mm Hatch Profile Rail with Pivot.

Total weight before glassing/re-enforcing = approx 1200grams

Final weight = approx 2500grams

This hatch system is designed to work with the hatch combing system that we have also developed. See Hatch Combings.
