Single axel trailer -coast to coast?

Never had to trailer a boat. Looking at a j24 on west coast to have towed to east coast. Would this be a problem on a single axel trailer?
Its definitely possible. I have towed my Single Axle all over the country including from San Diego to Charleston. I would recommend having the hubs tires and brakes overhauled/replaced before you go. Also I would practice with someone who knows what they are doing. A cross country road trip is not a good time to be learning how to drive a trailer. It should only cost a couple hundred bucks and most trailers are pretty neglected.

Or you could just buy an east coast boat, there are a ton for sale. Including mine which I will deliver, (Shameless plug I know, sorry I couldn't resist. )
