I know alittle long but does not take that much room. Trust me I have added things over time that I wished I had when I broke down. Obviously you add to your particular boat and its special needs. Always remember to offer to pay for tow in but never accept payment. When motor hatch is up, stop and ask if assistance is needed. Even if down if things don't look right, they proably are not. Ask anyway, you know we hate to ask "directions" we are proud types .
