The standard specification

• Stay arm

Houdini Marine has been manufacturing marine windows for over 30 years and Houdini Hatches have a worldwide reputation for robust construction, quality materials and economic pricing.

Retro fitting this hatch to a narrow boat is possible (we do it to our boats), but please note that the hatch must be fitted to a flat surface (see below).  Narrowboats tend to have curved roofs.  There are a number of ways around this, and you must be aware that the one we go for is expensive and involves fabricating a frame that is then welded into the roof.  This and other options are covered in Martyns blog article about Houdine Hatches.

Materials and Construction

Frames are constructed in marine grade aluminium (HE9). All joints are sealed against ingress of water, fish-plated and screwed. The seal is of extruded neoprene or similar. The hatches are glazed with 6mm tinted toughened glass with the exception of the Type 6 which has 8mm.  

Installation

All hatches must be fitted to a flat surface and bedded down on a good quality non-setting mastic. The outer flange is drilled and countersunk for no.8 self tapping screws or M5 machine screws.
