I finally got my '17 ProStar in the water and over to my Shore-Station. Now, I'm struggling big time with bunk spacing. I can't seem to achieve the correct width and height (for fin clearance over cross-bar). It shouldn't be this hard. If I go with 54" upfront and 60" in the back (which was recommended to me), it (I think) will make the boat sit a little lower (vs. closer-spaced bunks) and may cause the fins underneath to hit the crossbar when entering the Shore-Station. I also want to be sure that the boat is properly supported. Has someone cracked this nut and would be willing to enlighten me on the best way to go about this? Thanks in advance for your help!
