yes thats the scale available, but he may be getting them enlarged.
the main scale available for warships is 1:96th so you have to sometimes
enlarge them

40" or 1:96th scale is about the max I can physically handle due to 2 squashed disks in my back so thats the size i'll be building her at.
Going to be a fairly long build to give me the time to get a couple of test attempts at making a mold from a former and laying up a hull in grp with small test hulls.

If you made her to 1/100 scale, thus matching up well with the OTW Vanguard, the hull diameter-less sonar- comes out at near enough bang on 110mm, which is precisely the diameter of waste pipe tubing- cheap and readily available.

Now that just leaves you with making the upper supersturcture, sail, bow and end pieces, which you can make from foam, wood or whatever you have to hand, take plaster casts, then mould them in GRP.

Scribing and further detailing can be done on the finished castings.

Food for thought?
