It`s great to see that the F16 class has attracted a fair amount of interest from the smaller, existing 16ft classes that would like to keep up with the pace of more modern designs, even if they are 30 year old designs. It`s also great to see that the class itself is open to accepting their inclusion, even in some cases where they don`t comply fully with the rules. I think the approach has been to create a level-rating open class, rather than a strictly controlled class, which quickly turns back into one-design.
Looking at the weight of the South African Mosquito`s, we measured our boats at our recent Nationals & found the lightest Spinnaker equipped boat at 107kg (mine!), ranging to about 112kg. For interest sake my platform is 58kg, 3kg over min. weight. Obviously we are all sloop with extra weight of jib & blocks etc. The Australian Mozzies seem lighter overall, perhaps they have fewer fittings & lighter beams (we use a larger beam section). I think they are more obsessed with min. weight than we are, although we`re getting there. I think 95kg is possible if you strip the boat down to bare essentials and have carbon rudders & boards.
The min. weight of the F16 class is a good thing, as it allows a timber boat to be competitive, so exotic materials are optional, rather than necessary - well done to Wouter & the rest for keeping it this way.
As a matter of interest to the Australian Mozzie & Cobra sailors : We have had a large increase in numbers of spinnakers ordered based on the success of our Nationals, where the 6 spinnaker boats showed off their speed, we have 14 spinnaker boats at our next regatta ! To the Cobra sailors : I suggest talking to Tim (Mozzie) about standardising the spinnaker kits across both boats, it will make ordering spinnakers easier, and they have had a lot of design input from us, where all the learning curves have been made. In this way you will grow the class as quickly as we have here.
