conforming 1 mm plywood to front deck

Yes, I've done something very similar. I cut very thin ply, ( 1/32" in those days) into planks, about 8 mm wide, then double diagonally planked it. Sand back between layers, ensure your glue is applied properly. The result is light and strong. You'll need to assess the best plank width for your model.
   Much the same method is often used to plank difficult hull shapes like the bow areas of some RAF launches with double inward curves. There are some tutorials in the master class area on double diagonal planking. This used to be a very common way to make model and full sized structures.

I have just completed the pre-production (parts check) model for the new Perkasa kit. This has a section of bottom skin about 280mm long x 190mm wide which varies in section from flat at the rear to an internal radius of about 80mm at the front. I've double-diagonal planked it with 1mm x 10mm obechi strips. 2 x 0.4mm ply would be easier to bend - maybe in strips 8mm wide? You can obtain mahogany veneer in that thickness quite easily from Internet supliers, and it's probably quite easy to fit the first layer of strips across the deck and the top layer along its length i.e. they don't have to be at 45° to the keel.I used Slo-Zap to fix the planks to the stringers, with some SLEC Speedbond white glue along the edges where the planks abutt each other. Do check first because some hardwood veneers don't like cyano glues. The result was very pleasing and not at all difficult. As regards trying to bend a single sheet of 1mm ply around a compound curve, my suggestion is to go and learn how to knit with fog first... the skills you learn will stand you in good stead. Been there; done it; ripped the lot off before the glue had time to set!
The other solution would be to use good old-fashioned 'front-to-back' single layer planking in 1mm-thick strips, tapering the planks as you cut and fit them as would have been done on the full-size boat. Just ensure that you wipe off any surplus glue before it dries.

  Hi Dave M, and Chas, thanks you for posting here greatly appreciated I do recall seeing a planked deck
on an old mahogany speed boat, looked beautiful like the pic I saw of a double diagonally planked hull side same kind of pattern in design . The model I was looking at doing was originally designed for laying cloth material over the front or Oratex plastic film ? I wanted to take it a step further and do a nice mahogany front deck . I saw a bit of this technique performed in this fashion planking the hull sides in the master section. However I looking and do not see anything on planking a deck? is there any good step by step instructions on how best to go about doing this planking a deck double diagonally or front to back single layer, and what the end results of what people have achieved. I will try to post another picture of the boat a side shot you can see it kind of flattens out in the front a bit towards the bow.  Any more help would be greatly appreciated .

I only just managed on the cabin roof of my model, the side to side curve was about 3/8" over 8" and the curve on the length was less than 1/4" and it barely made those curves, your structure is much curvier so i am not expecting you would succeed in one sheet, and that was 1/64 ply
