Second, if you're headed out, do you know where you are going and how long the trip will take? Is it a cruise or a day trip? Chart, supplies, fuel?
Third, you should always be prepared to make mid-course corrections in case of weather, traffic, low water, or other challenges.
Finally, again fully communicate with crew and others your plans, changes, and goals. A voyage with a fully-trained crew can be a beautiful day on the water. The opposite can be disaster! The same can be said for a campaign. PLAN, COMMUNICATE, AND EXECUTE!
