For that sort of time in the water just use topside paint meant for below the waterline. There are many manufacturers... Awlgrip, interlux to name two. also gel-coat is an option. Why do you need to repaint the bottom anyway?
I'm not sure you "have" to use antifouling. In any case, it is up to you to decide how to protect your hull from the environment.
Not much help in actually answering your question (since I see you asked it on 2 different threads). Perhaps this is primarily necessary for large steel hulled boats/ships.
I have the original paint that my boat came with and the only problem i see is it gets a little dirty depending on where i leave it.. but a quick wash down when i take it out and its back to normal.. it will not hurt the boat
