Assuming that a zapcat used the same heavier hypalon fabric as your GRX, and was carrying all of the same kit, how much of a performance difference would you expect between the 2 boats?
Also, how would you rate the overall construction quality of the GRX?
I've also noticed that Gemini also offers 4.7m & 5.3m 'Dive' series SIBS with tunnel hulls. Have you had any experience with these?
Sorry for all of the questions, but I am considering one of these boats myself (or perhaps a used military Zodiac F470 - hypalon with the futura hull).
