Crazing of perspex windows

There are numerous reports in other forums of crazing of perspex salon windows and the fact FP is aware of the problem and refuses to address it. Do you, like me, have this problem and have you had any luck with FP?

Avoid any cleaner containing ammonia. That is often the cause.

As a matter of fact, mild soap and water with a soft sponge is all you’re supposed to use on plastic windows.

Re: Crazing of perspex windows

Like sails and most items on the boat, perspex wndows have a finite life and will eventually need to be replaced. Sunlight (UV) is the single biggest cause, but knocks from the day to day use of a boat will cause local crazing. Built in stresses from overtightening of fastners or cold bending will also accelerate crazing. As will flexure of the hull and superstructure in rough weather.

Our FP Maldives front moulded windows had to be replaced at about 15 years after 10 years in Med an 5 in UK. Our FP Athena still has original saloon front wrap around windows at 20 years in very sunny Adriatic, but she has been berthed with the boat Facing north for a long time and has decent sized eyebrows that provide shade. They are slightly crazed but not too bad. All the deck hatches acrylics were replaced after 18 years, they were very crazed but then they get full sun and get walked on etc.
So if your Lucia is in a sunny clime and hard used, it could well have crazed acrylics after only 5 years. Regular use of sun covers could extend life beyond 20 years

I should add that unless you able to prove that the crazing is the fault of FP's construction rather than wear and tear, you have zero chance of a claim against them. FP have stood by their boats with problems from vacuum infusion way after delivery.

Re: Crazing of perspex windows

My boat is 5 years old and the windows are protected by mesh sunscreens. No "harsh chemicals" have been used. I am compiling a list of the dozens of FP boats that have this problem, most in the 2016/17 range and mostly Lucias.

Re: Crazing of perspex windows

the hot bending of the windows and the stresses caused by the hull movements can cause micro cracks in the thickness of the plexi, and is it really cast PPMA that was used by the shipyard???

They may have got a bad batch or got ripped off themselves.

This kept happening to me with eyeglasses. I went to Pearle vision in New Jersey and I got the works on the glasses. Very expensive. They use polycarbonate lenses.

The glasses started developing cracks. Slowly. About a month after I got them. And over the next few months they became completely crazed. Difficult to see out of. And imagine driving at night with that.

They tried to convince me it was Florida Sunshine that was ruining them but people in Florida wear glasses.

They gave me a new pair. And they did the exact same thing!

I finally went to a different optometrist and had a new prescription a new glasses made. When they saw the crazed lenses of the old glasses they knew exactly what it was. It was inferior quality polycarbonate.

I got a new pair from the new optometrist and they are fine to this day.

So it’s quite possible that they got a bad or cheap or shoddy batch of acrylic for your boat. Or for several of the boats. They buy in bulk.


When it comes to something like this, all the energy you put into fighting it would be best put into just getting new windows. Total waste of time to do all of the fighting. And imagine how long it would take to bring your boat in and not be able to use it while they are servicing the windows. Not worth the battle. You should just get new windows.
