Different styles of floater bars/bow attachment points to the trailer.
This is the style that most people seem to like. This type requires a bar running down the center of the trailer. This style allows the bow of the boat to go several inches side to side on the trailer, not a good thing in my opinion. The floater bar is adjustable on the trailer which allows you to put the bow (or the stern) wherever you want it from front to back. Notice how it had to be bent to clear the bow's entry.

Same style, just a little different. The piece of wood is just holding up the end for the picture. Same "features" as the above floater bar.

This style is my personal favorite for a jet boat. The Newcastle beer bottle (courtesy marcsrollin) is there to hold up the end for the picture. The bow isn't allowed to move side to side. This style is non-adjustable.

And lastly, the family boat

This is adjustable and allows the bow (or stern) to be set wherever you want it on the trailer. This is the easiest style to use in heavy current (river) conditions. The bow is not allowed any side to side movement. A lot of people seem to consider this style to be ugly. (The bitch in the picture is my G/F's!)
