I got my C-Tug at the end of last week & tried it this weekend - works great with the boat & engine as I'd hoped & it's very manouverable...I need to get the straps sorted properly now with a side release clip (got some longer 40mm webbing as the supplied straps are only short) but my wife will get the sewing machine on the case for this!!
I'm Very pleased with the purchase & less than half the price of the Honwave specific transom wheels
I'll post some pictures when I get on the water again next.
