Greetings Paora,
Well if you were in the Northen Hemi I would suggest Polymarine, but sorry no idea in the southern hemi.
Question why Black? if you have a black boat people ask more questions, as there are a lot of boats that colour used for well lets say non legit activities - not that I'm implying anything as an owner of a large black inflatable my self (it came that colour and was free
with a few added ventalation holes
) I get asked them!
Paul lemmer wrote some articles for RI on the RIB industry in NZ in the last few months might be some contacts in that.
