You might know me if you were an assistant there....
The tomahawk took 12 to 15 minutes per circuit as it had to completely circumnavigate the rock and pick it's way past some biggish ships in the moorings. This, coupled with the landaway restrictions and the lack of much interest from the local population (youngsters too interested in matt black power boats) spelt out the death knell for any serious training establishment. We could reduce the time needed to clear the road cos they were so slow compared to the other usual types that used Gib. They only lasted one summer (1996 I think) before moving back to the UK. We had a Teal amphibian operating there at the same time doing pleasure trips around the rock and up the bay... I think he stayed just over a year. If I remember rightly the tomahawk had dispensation to operate within the arrester gear assemblies as well.
