TECHNICAL WINDOWS & HATCHES

A leaky hatch or window can make life down below miserable. Duncan Kent explains how to ditch those drippy blues forever

- 

Every boat I have ever owned has had at least one leaking window or hatch at some point and, from experience, no amount of temporary bodging has ever succeeded in fixing it for longer than a few days. In the end, the only way is to do it properly. Despite taking longer, there’s nothing better than knowing you’re leak-free when the skies open or a huge greenie comes rolling down the sidedeck.

WINDOW REPAIRS

Scraping and back-filling will only last a short while, especially when the old sealant holding the glass in the frame has deteriorated beyond all recognition. The typical butyl sealant used for sealing glass into frames and frames to the cabin has a working life of around 20 years maximum. The first bit to go is usually the top strip, where the strong rays of the sun break down the butyl into a crumbly, powdered mess.

No matter how experienced you might be at removing windows and hatches it always turns into a long, tedious job, so make sure you put aside a few days and do them one at a time to avoid having to tape tarps all over the boat.

If you do plan to remove them all at once, do mark all the components of each window and hatch with numbered tape (including any fixings) as it’s very likely they’ll all be a slightly different size or shape, so you don’t want to muddle them up. Also, mark the orientation of each frame so that it goes back in the same way, ensuring the mounting holes will line up.
