I am just now ready to install my set of Row Wings in my Tandem Wherry.  I noticed there is now specifics on mounting the seat rail in the boat.  Also, the size of the bolts for mounting are unknown.  If anyone has installed this seat system before, I would love to hear the measurement specs on mounting the rail (eg.  How far is the end beyond the front bulkhead?). What size bolts did you use?
