Type XXIII, Gotland, Typhoon, Akula, Type VII (probably B variant). Dunno about that stupid looking yellow thing in the middle though, who'd be barmy enough to build one of those.....! -

Almost there with it. The big stumbling point has been the onboard sound system, chiefly getting a decent tone and volume from a system that can withstand the elements. Now I could say, sod the beatles, and nix the sound system, but I think it's such an intrinsic part of a working model of the yellow submarine, it has to be done.
Experiments so far have proved a bit disappointing- I tried using nxt sounders, these are like a voice coil of a loudspeaker, but minus the diaphragm. The idea behind this was they could happily live in the free flood area, and use th hull it's self as the sounder. I have found that drivers small enough to fit in the small boat, work very well with lightweight substrates like foam, but not so good on a GRP hull, which is quite rigid and firm. Now you might say i could put a foam sheet or board under the hull and use that- true enough, and I considered that- problem is packaging- the shape of the hull doesn't lend itself well to a wide flat sheet being placed above the waterline. In addition I found the sound level given out was low when compared with conventional diaphragm based drivers. So they were inefficient- not good in a battery powered craft.
So it's 'plan B' which is to incorporate one or two small high excursion drivers. These will most definitely give adequate sound pressure levels from a small amplifier of about 1W RMS, but bring their own special challenges.Comment
