I can see why people want auxiliary motors or twin screw vessels, but it is very expensive insurance considering that you have VHF, Flares, EPRIBS, mobile phones, V sheets, anchors, sea anchors and other vessels that are always out. Just one thing to take into account when toadys outboards and much more reliable than they ever have been. It maybe an option to sell the tinny and outboard and the yammie and repowering? just some food for thought mate.
