A thru hull transducer should not interfere with trailering the boat at all. If you are worried about cutting holes in the bottom there are some units that can be mounted inside the hull, they shoot right thru the bottom of the boat and work great if they are installed right. Not sure of the cost. I would go talk to the guys at consumers marine. They know their stuff over there and have most of the toys in the store so you can see it before you buy.
