Might be a little late in the year but a head's up if your float aircraft sits at the dock & you get snow; make sure that at the very least you keep the tail feathers free of snow - if the back end loads up your aircraft will sink. It is always best to keep all the snow off the aircraft,but the snow load on the tail puts the back end under water with the weight & then the rest of the aircraft follows it.
Yup, mine sunk from 4" of wet snow. Luckily it was only in 2' of water. I have a dock on both sides and now when I leave it in till late November I stick a line under the heels and pull it tight to both docks. It will have to sink the docks first now.
