Hi tworotorturbo,
Your post regarding your Red Knight popped up on my google search about this rhib builder here in NZ.
I'm in asimilar situation to yourself in trying to identify a rhib I have recently purhased for the purpose of putting into survey to run on commercial diving jobs here in Auckland.
Survey requires hull plans or histry of sister hulls being in survey but this hull has no identification at all! The seller intimated that it had been in naval use which is why all ID had been removed.
Any help in identifying this hull would help me out alot as I've drawn a blank with queries from the Navy.
By the way, internet searches on Rd Knight have a tenuous link to another Auckland based inflatable company caller Terminator Boats. I'll be talking to these chaps as well.
