Many thanks for this. From what I can see I am pretty sure it is a petrel, as it is light, and has room for two at a squeeze! It also has boyancy fore and aft and not under the seats as a storm 15 appears to have. I have not tried her out yet, but several posts suggest she is likely to be rather tippy so we will just have to see how she sails, having been used to a GP14 and topper in the past, although I have sailed a laser a few times. All this was several years ago when the children were young!
