I would do everything I could to get the boat on the beach and tried down. We had T storms a couple of weeks ago with wind gust up to 45mph and this will happen all summer in the LI area. I also think your rigging will take a pounding if you have any boat traffic or wind chop. So if your boat has not capsized it will most likely be dismasted when you return. Bottom paint is very slow and belongs on a powerboat not a beach cat.
