Question

Question:

Have 18ft tidewater sitting on 2x8 vertical bunks. Would like to install roller bunks. What is the height the rollers add to the top of the bunks? Also, do you have to slide bunks in slightly to not be on the strakes?

The Boat Trailer Standard Roller Bunk # DL21754 is going to add 3" of height to the 2'X8" vertical bunks that you have.

We do have the Boat Trailer Roller Bunk Bracket # DL21762 that can be used if you feel that the rollers and bunks would raise the boat higher than you would like.
