On the subject of the V-berth in a R25, let's talk a little about comfort. My wife and I (right around the magic age of late 50s to early 60s that so many folks are when they move to a Ranger) could not sleep on the standard V-berth cushions without tossing and turning due to aches in the hips and shoulders. There have been other posts about this, I recall Denny-o including the need for softer cushions in his list of improvements he offered to the Ranger factory...
My second day on the Ranger brought to Wally-world to buy a 1 and 3/4" king size piece of memory foam for about $80 which helped very little. I headed to my local upholstery & custom bedding shop (Nix Upholstery in Sanford, FL) for advice. They explained that memory foam compresses to almost nothing; its designed to nestle you in a womb-like state not "support" you. I made a template of all my V-berth cushions and they started work on making a 2 (like half-moons) covers to enclose a medium weight 2" piece of foam. Before they finished, we tried the foam and still had sore hips. Nix then added a one inch topper of soft foam, and that did the trick.
When you contemplate this (as sooner or later you must) you'll worry about head room as you sleep with your head under the back of the dashboards behind the AM/FM radio and the helm. Even getting up frequently in the night to visit the head (ahhhrgg, getting old is such a drag) I never once clobbered myself at 6'2." It is a little claustrophobic with a thicker pillow, but its worth it.
Next step was to buy king size flat sheets from Macy's. No one else sells them separately, you usually have to buy a fitted sheet and flat sheet together! Being unfamiliar with sheet buying (male, I guess) I was shocked to find out a single, mid-quality sheet cost about $60! I bought four and Nix made 2 fitted sheets for the entire assembly and 2 V-shapped flat sheets to go on top. This provided spares. I think I might, next time, get separate sheet setups for each moon shaped section so that my buddy (he prefers to sleep in the cave rather than with me in the V-berth-get a load of that! Some nonsense about snoring or whatever!) is with me he can drag one assembly into the cave as those cushions are just as hard as the V-berth. I'll pull out the Walmart plastic storage drawer sets and just stick them in the empty side of the V-berth.
I think Nix kept a pattern of my V-berth cushions. If you draw one yourself around your cushions, remember they nestle UNDER the cushioned side panels (BTW the bolsters are easily removable, just yank straight up). So the covered cushion(s) you have made need to be reduced 2.5 inches on both sides to fit AGAINST the bolsters. I'll try to post pictures in future of this solution to the factory standard very well made with excellent fabric cushions which are just too d__n hard.
Afterthought: If you involve an upholstery/sewing outfit, get them to reduce all your factory supplied curtains (except for the front two opening large side windows) by taking 2.5 inches off the bottom to neaten them up. All the curtains are one size, even though the windows are not. Don't forget the curtain in the bath, like I almost did... This is a huge improvement.
AfterAfterthought: The very nice cushion that you find in the cave to set on the dining table to make a berth is huge. It won't fit in a 30 ga trashbag without folding, and it takes up an entire dock box when you want to leave it behind. My house is in Mass and the boat is in FL so storage is a problem. Solution-Nix cut the thing in half, sewed on some nice fabric to make a hinge (which is concealed when the thing is opened) and now it fits in lots of places around the boat.
