Shotwick Park sailing club

A very dull day, but I wanted  a photo of something white for an upcoming club competition, so I went to the local sailing club. Always very welcoming, they let me potter round the edge of the lake, trying out some ICM. There are 3 in extras. Please, if you've got time, have a look at them and tell me if any of them look okay and/or suggest how to improve them. The brief is very simple...White, and I fancied trying something a bit different.
