Yes, but even the S boats are/were bigger inside than type sevens. Thanks to family connections have been aboard S,T and V boats with a "Round the bay and back in time for tea" on Spartan many years ago. Given that "It turns and banks like an aircraft" (Captains statement), when asked if I wanted to drive it, I declined cos they wouldn't allow me to loop it. Ward room on a "V" is massive.
Re "Head banging" gingyer, I noticed the bits poking out on first visit on board Swiftsure. In industry, all drawings I produced had "Remove all burrs and sharp edges" printed on them, so quite a surprise when confronted with lumps of metal with corners on them. When questioned about it, eldest remarked "It doesn't take long to know when and where to duck". Now given there was a problem in "Daylight", think of a fire drill with reduced lighting. Given that there was a lot of formica panels making it look like a windowless caravan, at the end of the day, they are warships. Given the windowless state, one of the crews mum asked "How do you see out?" Lad turned round and said "Me Mum thinks it's like the b****y Seaview."
