We hopped in and out off the trailer several times, threw my 2 1/2 yr old son up & in about a dozen times (I love that my son loves boats!) and never noticed the tower being in the way. Maybe different from a dock. Might have to ask to take that boat out for a test run to see if that's going to be a problem.
The bigger issue for me with that tower is the inability to have a Z5, or similar, bimini. After using the Monster Cargo bimini for the last 2 seasons, I'm a big fan.
