Yeah they are great to watch we were fortunate to have a number of them based out of our club for a while https://vimeo.com/156693472 and the Redline racing team are based out of the club so maybe we will get one back sometime. If you get a chance to see one up close the carbon fibre engineering on them looks amazing!
Most of the F18s in Western Australia are at another club and they are mainly Hobies etc; we have just got a fleet of Hobie Waves at our club for teaching sailing, and some Nacra 15s and a Nacra 17 for some talented rising stars.
Where are you based, it looks like you are on the same time zone as me on your profile?
