What Clients think of us...

Difficult to source spares for older boats and the chaps at Eagle Boat Windows went out of their way to help. They gave me some great advice and I now have windows and a new hatch which not only are water tight, also look very smart!

Dealing with Eagle Boat Windows is like my idea of a rail trip in Utopia. All the information required for route planning is clearly presented, telephone enquiries are handled courteously and knowledgeably, the fare structure is clearly presented, and everything runs very much according to timetable - definitely a Pullman experience.

Didn't realise how bad the perspex had degraded but the boat looks new and visibility and light greatly improved.
Based in the lake district so all seals have been seriously tested and no leaks!
All set for the next 20 years of service.
Great Job Rowland and team, thank you, Dave and MC

The big problem with removing this hatch is that the four hinge bolts are embedded in the GRP deck and once removed cannot be simply put back, so I removed the nuts by drilling down backfilled the holes with epoxy putty and when set replaced the base on a butyl tape seal using the existing screw holes and then re-drilled the four hinge bolts right through and fitted washers and dome nuts. The hatch looks like new.

Eagle Boat Windows is a specialist marine window and deck hatch refurbishment and supply company with over 30 years experience.

Put simply, we take leaky, crazed units and transform them into ones which are dry and clear..., or source new replacements...


We offer services to private boat owners, refit yards and commercial clients (including the RNLI).  We are particularly pleased to partner with Lewmar in Europe, covering their Custom and Heritage ranges.  We are also agents for  a growing list of worldwide manufacturers, supplying spares and replacement units.
