    We have upgraded from our old (small) dinghy to a 14' Zodiac with 50HP OB. Total weight is around 625 lbs. We will be towing it behind our 340 Sundancer. I do not trust a single connection point at the bow eye (U-bolt) for towing, unless in calm water at no wake speeds. My goal is to be able...
