-Thanks for that, I will have a good look for it

I have been working on how to get accommodation in the lw hull without
excessive beefing and it is not easy. This has been part of the
argument of Pacific against Harryproas. I have gone for simple hatches
in the top, leading down steps into the centre, as well as hatches
over the bunks. This allows continuous lines to be drawn from the
masts to the opposite. This just leaves the edges of the hatches to be
reinforced. It may be possible to put steps up to the top and down
again to get down to the dock over the lee hull. It is possible to
have more holes and easier access but requires a lot more fiddling,
time and weight.
