Lets begin this piece by asking a question; how often do you consider the tides before going for a surf? Playa Guiones, where the Surf Simply resort is based is lucky to work all the way through from high to low. Where the tide is at any given time though may influence certain decisions before we paddle out; like for example where to surf, or which surfboard to ride. Typically at high tide there would be a slow, fatter wave breaking, and a fast more hollow wave breaking at low tide, with those characteristics transitioning through mid tide. This becomes even more critical when we travel up or down the coast

In late August 2017, the Russian icebreaking liquefied natural gas (LNG) carrier Christophe de Margerie made headlines in maritime traffic news for a record-setting transit of the Northern Sea Route (NSR). The ship transited the 2,193 nautical mile NSR in just six days, twelve hours, and fifteen minutes. It completed the entire journey from Hammerfest, Norway, to Boryeong, South Korea, in nineteen days—nearly thirty percent faster than the traditional Suez Canal route. During the transit, the vessel averaged just over fourteen knots, remarkable given that part of the transit was through ice fields that were 1.2 meters thick.1)
