Modern Glass in Maddington.....you want it toughened to Australian Standards and the same thickness as what you have in the half windscreen.   You should also consider having it professionally "enduroshield" coated .....will last at least two years and water just sheets of leaving it clear as.

And much cheaper than you might expect !

They did perspex and surrounds for me but sure they will do glass - professional mob.

Hi Mcfisher, apologies for the frat but I hope this advice helps because I hate seeing a fellow fisho ripped off. My father-in-law and I have repaired two curved corner windscreens of my stacer with little trouble and even less cost. We all know the any business to do with marine supplies and repairs take the piss cost-wise and nothing epitomises this more than these types of repairs or replacements. As a footnote, prior to doing the repair ourselves we contacted a number of companies here (inc the one above) and the cost to repair these simple items and the downtime were both ridiculous. Anywhere between $1300 and $2300 depending on who you speak to around town. Most others you speak to make it very well known within the first response they simply cant be bothered. For example, if you have a Stacer and go through their WA reps Hitech (who I’m a big fan of) even they will ask that you provide them with the broken pane still in the framing (you obviously have to remove the frame) as a whole and they will send the LOT to Qld. Crazy… First thing you need to do is research the various ways of repairing them on the net and Youtube. Some excellent vids and advice on there. You then take your time in slowly dismantling the framing from the hull and ensuring the seals are not damaged. Generally these windscreens will break in a few pieces or just have a hole punched out of it as was the case with mine. If it is in a few big pieces then super glue them back together roughly. Not a big hassle. The most important part now it to make a paper or cardboard template. Once you have done this it is literally 90% complete. Go out and source an Acrylic or Polycarbonate sheet from a plastic suppliers and using the template cut yourself a new windscreen. Using a heat gun or as one fella on youtube did, their barbie ( lol)… slowly heat the piece so you can bend it comfortably using gloves and whilst in this state commence placing back in the seals/frame. You put it all back however is easiest for you but I mounted the bottom frame first, then put the sheet in and then the top frame on. Rivits and marine silcome etc. Don’t be daunted mate. You’ve got this. A little time and patience, some beers and a laugh if you’ve got a mate helping which is recommended. Ignore the people who believe it needs to be tempered etc because tempering only adds further strength and gives it resistance to extreme temp fluctuations. Acrylic/Polycarb are tough A.F and both the windscreens I have replaced are still superb, still clear and very difficult to scratch. Acrylic dearer than Polycarb but the Poly carb sheet I bought was $90 Fuck paying these expert “repairers” 4 figures…….

And gave Moderns the two panels which form my front windscreen (as they weren't exactly the same size ) and the cost was under $400 for the both AND the two side panels.   my seals were perfect, just had to carefully remove the marine silicone remnants, don't use too much in the reinstall, it goes a long way as it only really forms a film between the seal and the glass and cleaning up excess is a bloody pain in the proverbial.  

Pescatore how long do you think the acrylic will last exposed to sun? i have seen plenty polycarb screen with "crows feet" after only a few years!!  Sunshine were your 2 pannels just squares/rectangles?
