I have an 8' Rib which I carry on the deck of my 50 bertram but it is a royal pain to lift it out by myself (after I take the Johnson 15hp off). I also have a 13' Boston Whaler which my wife & kids prefer. Question: have you ever seen someone tow a 13' Whaler at around 22 kts? I figure I could make up a "Y" to attach to both stern cleats & then run the line back to the Whalers bow eye. I figure 1/2 to 3/4" line would do the trick. Do you see any problems with this? Any ideas?
