A trailer with three wheels is going to be very difficult to tow.
I suggest joining a forum that's more focused on trailerable boats and asking your questions there.
Surge and electric brake systems are very different. An electric brake system requires a cab mounted controller and a battery on the trailer. Surge brakes do not, but electric is a better system for heavy trailers.
You need to know the total weight of the boat and trailer and compare it to the tow rating of your vehicle. It's not safe to go over that rating although a small amount for a short distance on relatively level ground without a lot of traffic is probably OK.
