If I remember correctly, the ICCT only agreed to use the Bimare F18HT for two years and this is the second year. I assume that the motivation for the original switch was because of a lack of activity in the C-class catamarans (which is probably debateable). Switching to the F18HT has definitely brought about a new era with a challenge every year and tons of talent (which I like) but we did certainly loose an aspect of the development that takes place with the C-class boats. I assume that the intention of the ICCT may be to open up the competition to full 18HT rules which does allow a bit of development. Perhaps their intention might be to switch back to a c-class format now that the c-class cats are visibly active again and attention surrounding the ICCT is relatively high.
I'm only guessing and proposing possibilities but I could argue either way regarding who should keep the nickname and as such I agree that nobody should use it!
