A cunning plan...

[Gordonmc]

I have a fairly normal set-up for sleeping berths on the boat... bench seating that makes for comfortable single berths... forecabin with the usual V space, singles either side or with an infil, a double.
Staying with the forecabin... the sigles are a bit narrow. Using the infil means falling down the spaces between the mattress sections.
Making one big triangular mattress would provide the comfort... but would be a no-no... too big to get down the companionway... a bind when you want to get the stowage beneath etc.
So... what about those inflatable mattresses you keep in the garage for when your most hated auntie comes to stay (and you end up sleeping on the thing)?
Obvious problem - the shape. Oblong, so no good.
Answer... get a limited batch made up, triangle shape. Sell em to yotties and anyone else who has three-sided kips.
Lots of advantages... they take up no space deflated. Blown up with a dinghy pump, perfect insulation etc.
Is it a goer? What size would be suitable for a generic forecabin mattress?
This is not a troll. I will approach a manufacturer if there is interest.

Sounds like a plan but surely some company does them?

Why not just have two cushions by joining the infill to one of the mattresses. That way it doesn't fall out and you can still lift each side independently to get to storage.

 

[Krusty]

What about joining the infill to both mattresses with fairly heavy-duty velcro?

 

[MoodySabre]

Or a chunky zip on the bottom edge.

Buy a cheap double bed inflatable like Aldi sells for example. Cut into the desired shape after some considerable careful planning. Glue the seam back with the appropriate glue.

Think laterally. Have two cushions but instead of the join being fore 'n aft, make it beam to beam.

Make the singles wider and have one 18" higher than the other so the feet end at the bow cross. Bigger bunks and space still in the middle of the fore cabin.

Different boats, different bunk sizes and angles, so mass production problematic.

another vote for two beam-to-beam.

Thanks for input.
Beam to beam would restrict use of the forecabin to one double.
Essentially I would like to do away with foam mattresses in the V berth. They are a bind to take on and off by dinghy, have to be stowed upright to keep damp at bay and take up too much space (wooden boat on a swinging mooring).
I am speaking to a couple of companies making bespoke medical inflatable mattresses with a view to having some prototypes made up, having found the inexpensive ones all come from China, but doesn't everything?
Fishermantwo: good notion, but the bought inflatables are welded rather than glued.
Csail: I like your thinking... its such a simple idea someone must be doing it. But they aren't!

You can buy relatively inexpensive foam "mattress pads" - something that you would put over a normal mattress. They can be rolled up for transport (although perhaps best not to roll tight for storage on a boat), and could be cut to fit. It should cover any gaps in the underlying cushions.

But you'll still have the foam cushions.
