Got an approximate 35 foot long pier. Wanting to mount some cliets so friends and people stopping in can use them. Want to be able to accommodate Speed Boats, Pontoons, and Wave Runners. I've been told the distance apart for certain size boats. That doesn't help me because I don't know what boat, pontoon, Wave Runner might be stopping by. Could someone just recommend a good average distance apart? Thanks. PS Maybe someone works at a Marina and could tell me what they set theirs at? Thanks
