Has anyone had a custom cockpit windscreen made up? The project in mind would be for a 5 pane alloy framed windscreen tough enough for offshore yacht speeds, about 6ft wide, 2ft high and probably 4ft deep with 2 long side panes. The frame would need to be strong enough to support a further canvas pram hood.

Just looking for a ballpark cost excluding fitting, to the nearest £1000 would do.

I would provide a wooden template.

I'd guess that you wouldn't see a lot of change out of maybe £7K if you want a decent result with a custom design. Windscreens as fitted by HR, Najad, etc are very substantial bits of kit. I've replaced the fixing rails on my HR screen, and can assure you the screen is heavily constructed!

Ouch, I was expecting the grp plinth to be the expensive bit.

My hope was that making it from flat panes would keep the cost down. Looking at the HR example in the OP, it seems to be a welded bottom rail into which the panes and alloy uprights are fitted.

These guys do all of the Nauticat window work and I see that they also do the windscreen construction which you are after. Worth a look?

Ertec is the company which took over the Bjerg windscreen business in 1997. Bjerg supplied windscreens to HR and others for many years. The drawing of the Panorama screen on their website is the one which used to be used by HR.
 
Made my own 5 panel windscreen, similar to your picture, out of GRP with perspex windows, and it has been a great success,

Made a female mould on the boat to ensure angles and sizes etc were as required, with recesses for the perspex windows, and then laid it up at home in a couple of hours. (surprisingly large item to transport from boat to home without too much distortion).

Windows were recycled from an old notice board and were 27 years old at the time and have now served a further 7 years and are wholly reliable. The top of the screen has a return flange to give it rigidity and it has stood up to green water over the decks without problem.

Also made my own pram hood which attaches to the screen and gives cockpit protection.

A satisfying project which was less than a couple of hundred £ in total.

Fascinating, presumably the framing of the windows looks a bit heavier than alloy because of the need to build up some strength in the grp pillars? Have you got a photo?

Are the window frame moulding and plinth the same laminated structure taken down to the coachroof? I ask because this is the element of the job that seems to be the biggest challenge i.e. following the contour of the roof.
 
I have costed a 10mm polycarbonate 4 piece screen using curves as a structural support, with alumiinium anodised frame above and below to support fixing to deck and for srayhood and (stainless) grab rail.
Around 3 grand.

I dont like the flat screen slab arrangement, so mine is based similar to a Beneteau 36CC.

Polycarbonate... will consider that. At the end of the day a framed canvas sprayhood stands up to the elements so the structural challenge is not immense.

Noted, I suppose curved panes allow you to follow the existing curved sprayhood mount moulding in the coachroof?

My preference would be for 5 panes to accommodate a central lift-up panel to encourage a draft into the cockpit during hot weather or a clear view forward when drizzle is sitting on the screen.

An outboard grab handle, yup that is another feature I want.

Anyhow £3k, that is closer to my original hunch.
 
I will be making my own mould tool from laminating plyskins on a frame built up on the boat.

The plastic will be hot box formed and put to shape around the former.
Care is needed to stop the material boiling and ending up with air bubbles inside, and stress lines in the bends.

This is what saves the time and money.

Material is around £350 per sheet, 2 required.
For jonjo: I had intended putting a swing up panel in the centre which also aids access to the mainsheet traveller.

The sprayhood will be in offwhite with clear plex panels
