hi steve,
you don't say where your interests lie in the sphere of models boats, but have said that in the past you have had a 1 to 1 fishing boat.
from what i understand of M.S, you might find at times , difficulty in holding small objects.
the reason i ask this is to firstly narrow down a scale that you might be comfortable in working with.
if my assumption is correct, you might find a little difficulty at times in working with small scale and fidly bits.
i do appologise if i am incorrect, but there are some splendid boat hulls especially fishing boats such as the CYGNUS boats on offer from andy grigg at
www.modelsbydesign.co.uk , and in larger scales, or you might fancy a lifeboat at 1;12 or 1;16 scale of which there are manufacturers of both scales around..
i hope i haven't been too presumptuous with your illness, just trying to point you in a direction that might help.
all the best, and enjoy the forum.
neil.
