We show you how with our step-by-step guide.

White spirit should remove the rest.<br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/7.jpg"><h2>7.JPG</h2>We went for a new Gebo hatch that didn't have a vertical flange, giving more scope for adjustment. <br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/8.jpg"><h2>8.JPG</h2>We decided we would be spending more time at anchor, so orientated the hinges for forward opening.<br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/9.jpg"><h2>9.JPG</h2>The hatch is lifted off again, the swarf brushed away and the deck is lightly abraded to provide a good key for the sealant. <br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/10.jpg"><h2>10.JPG</h2>Waterproof marine sealant is spread generously onto the hatch, creating twin beads of about 6mm on the inside and outside.<br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/11.jpg"><h2>11.JPG</h2>Placing the hatch carefully into position, the screws are then introduced and tightened in a diametrically opposed pattern so the frame goes down evenly.<br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/12.jpg"><h2>12.JPG</h2>The sealant should be 'witnessing' at the edges, but the hatch shouldn't be so tight that none is left as a bed. <br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/13.jpg"><h2>13.JPG</h2>Finally remove the protective wrapping. Don't be tempted to leave it on to protect your new acrylic over the winter, as the UV and rain will create a sticky mess.<br><img src="http://www.mby.com/wp-content/uploads/sites/18/2013/11/14.jpg"><h2>14.JPG</h2>The finished hatch: it looks good and is easier to use.
