Darn good list going there -- for a skipper new to boating.1) Ensure that your fuel gauges are working properly.
2) Learn how much fuel your boat consumes.
3) Take your time! Launching, docking, rafting, trailering - rushing any of these leads to silly, costly mistakes.
4) Never take boating advice from anyone who has never owned a boat.
5) Finally, use your boat and use it often.
