Weather and sea state are major factors to safety on the water. Weather becomes even more important as you venture further and further offshore and away from the relative safety of inshore waters. For long distance cruisers and passagemakers, weather becomes a critical factor in planning any voyage.
Some of the important aspects for the mariner: The wind and sea state affect dead reckoning, reduced visibility limits piloting, and overcast and clouds prevent celestial observations.
Secondarily, weather plays a vital role in enjoying your day on the water. While your boat may well be of a size and seaworthiness to easily withstand a gale, who in their right mind would enjoy their time battling 47 knot winds and 10 to 14 foot seas if you don’t have to?
So... Know Before You Go! Before casting off your lines, be sure you check the latest weather forecast for your area or planned route of travel. And be sure that you understand what it means.
