If your Bavaria is fitted with Rutgerson portlights as mine is, you will find the makers' screens VERY expensive indeed, almost impossible to source in the UK and of course you will need at least six of them. As to deck hatches, I have just bought two more "MariNets" from Compass24.com - but watch out they misquote sizes on their website and something massive arrives if you order the 62x62 model. The one you want for Bavaria hatches is the medium sized one stated to be 50x50. Mine had to be swapped. For the half sized deck hatches - mine are Gebo (as Bavaria exchanged the original Rutgersons under warranty as all the hatches leaked at delivery although we decided to keep the Rutgerson portlights as they looked good) and we use netting bought from a bridal outfitters with a hem sewn around and thin elastic pulled through it. These fit perfectly over the lip of the open hatches. The commercially available netting sold for UK marine use is no good in the Med as sandflies can get through the coarse mesh - incidentally, this is also true of the Rutgerson made fit-in screens. The Bridal Veil material, although not as UV resistant keeps all flying raiders out. The MariNets have a UV styable version of this fine mesh.
I got mossie proof fabric from www.pointnorth.co.uk they also supply elastic . You can make your own easilyJust ensure that you measure and add enough to form a hem to put the elastic through.(got it right second time). they work for the Med mossies.
We've found in the Med, almost everywhere that has mossies, has shops that sell mossie screen material by the yard.
Usually a plastic coated material that comes in different sizes, thickness's and colours. The plastic helps keep the shape and still lets air through. A local hardware shop here in Corfu has a least 6 different types and a selection of frames, tapes and edging strips for it - all very cheap.
I'd suggest a local search wherever you are will turn up something similar. After all, the locals have the problem permanently !
Similar theory to everyone else, they are a definite must! We got our material from a market stall in the UK. As before make sure you get the fine stuff, never thought of veil material!
The netting we got was quite wide and flimsy, very effective but haven't got them mounted yet! Sewed a hem round but it seemed to stretch a bit. Think we'll knick the elastic idea! Do you have to stick them over the outside of the hatch when it's open, am I understanding the idea correctly? Guess the rigid stuff (seen it in most fereterias?!) would be good for the washboard equivalent as it would remain rigid so could be cut the the right shape and stay like a lat to slot in?
My partner suggests that if your hatch isn't suitable for elastic then lead line (used for fishing) in the hem would hold them on when laid over the hatch from the outside.
Everyone is working on the same theory, I think, but a word to the wise, we are based in the Costa Del Sol and have white mossie nets (up through temporary means) and they get absolutely filthy when the hatches are open with the sand that blows over from Morrocco. Not quite sure what a suitable colour would be to replace them but just a thought before you buy! /forums/images/graemlins/wink.gif
I can't remember for sure now, but I think I got my plastic mesh from a gardening shop in UK.
Was also told that taking Yeast tablets starting about a month before 'exposure' discouraged Mosquitoes. I can't say it did much to stop the big beggars at Port St Louis though. /forums/images/graemlins/mad.gif
If you just need the material to make them then call into any local curtain shop. We used the net curtain material and it's still going good after 2 years. It's so cheap to buy that it's not the end of the world if you screw up the design.
But agree with other posters, they are an absolute essential.
We have a net that fits over the companion way with the top either open or closed and one or two (out of three) boards in place. The forward edge is elasticated using the broad elastic from an old pair of braces (long trousers not needed in Med!). It is stretched from one side to the other and secured with turnbuckles. The sides and the bit that hangs down where the hatch boards have been removed are kept in place by curtain weights sewed into the hems. It works very well, though after 9 years the elastic needs replacing and I have no surplus braces anymore!
We made our own, just used a fine net (Ex Military Supply) and hemmed in a length of rope, drops over the hatch nicely, takes up a small space when stowed being soft and floppy.
You can buy ready-made Mozzienets in Mothercare (£4.99) designed to fit over a pram; they're basically a squre of fine mesh material, with elastic sewn into the hem, and will easily fit around a 63x63cm Lewmar hatch profile.
We also have 2 big pieces of net curtain material, with ready-weighted hem, that we overlap and peg to the sprayhood rim at dusk: it drapes nicely over the cockpit seats and makes it very easy to come in and out through the companionway steps without having to undo anything.
