Anyone have the details as to what is going on and which models & years it applies to?
Yes my Leopard 44 2015 model both starboard windows cracked from the base. I can only put it down to hot weather. Both cracked a day apart. I contacted Leopard Australia with no knowledge of this happening reply. Only a popped saloon window on a Leopard 40.

You can't put this down to "hot weather". It is bad design. There is absolutely NO reason that "hot weather" should cause windows to crack if the fixing and bedding is properly done.

"Only"? What do you do if your saloon window "pops" in bad weather 1000 miles offshore?

Re: Leopard cracked Saloon Window(s)

I've done a bit of research the past days (and still in the process) and I've seen experts state that both polycarb and plxiglas has issues with getting them watertight, especially over time.

Given that, tt seemsA factory that puts out a few hundres boats a year, will have a few boats per year that get leaks in the windows. In fact, almost every youtuber seems to have some degree or occasions with leaks in the portlishgts windows, from time to time.
Now... I'm looking into buyng a leopard, so I'm very interested in finding out if Leopard has more leaks than others, or if it's just a normal rate of leaking windows?

One comment on the poly vs plexy. Yes, poly is stronger, but it's also less scratch resistent, and will turn "milky" quicker.

Have a great weekend.

Kind regards

I had a C&C 34. They had dark grey plexiglass side windows and they leaked. I used Sika 295UV to put them in. I followed the instructions and used the primer. Next year they leaked. Same thing .... The problem is that 295UV will not bond directly to the acrylic so they have you paint on a primer that bonds to the acrylic and then the 295UV bonds to the primer.

Acrylic is actually hard to bond to.

Now I use this

Atkins & Hoyle use this product

I have an acquantence who says you need to hit the area that the SCS bonds to with acetone to ensure the SCS sticks well.

We had a huge skylight in our 86 Bene when we got it and the glass was cracked. It was bonded in with some kind of a rubber compound that was so well adhered to the acrylic and the gelcoat that it tore the fiberglass off the boat when we removed it. I would like to find that stuff.

We have friends who have a Jeanneau Sunkiss 47 with great big long windows over the main saloon and they keep cracking due to expansion and contraction.

I am not sure your correct about the cracking. The coefficient of expansion is so much greater with the acrylic than with the fiberglass structure it is bonded too. In my mind this is not actually the proper way to build windows but then I am just an end user.

aluminum frames are in my mind much safer and big sheets of plexi glass scare me for exactly the question you ask. What do you do if your window pops 1000 miles offshore.

I knew a guy who headed out across the Atlantic with is 2 sons and a buddy. Headed for the Azores. I heard the story second hand so don't know details bu....

Apparently they blew out a couple of windows and as a result could not go onto a port tack. ( no batten boards? I thought this was a basic.) They did not make the Azores. They landed in Africa. It was not a nice trip.

Re: Leopard cracked Saloon Window(s)

The summary of what Iíve heard and was told is that the L44 has suffered the most with cracked and leaking windows, apparently due to a build with thinner, lighter materials in the areas around the windows that flex. The windows then crack or move creating leaks. The factory and shops that service Leopards are aware of this, and it ďmayĒ very well be one contributing reason for the shorter production of the L44, leading to the L45.

Regards,
