Search Google: SHIPS WAKES TURNING
My Experience is from Haro Strait at and below Lime Kiln. Lime Kiln and Bailers Pt see 'large' swells with only a passing Chinese hull near the border folloWing the ship's turn into Haro from Juan de Fuca. The swells and position of the hull
do not match the usual passing hull/swell timing. Nor the swells heights. At normally low Strait speeds traveling up and down the Strait, new Chinese hulls at the border throw low height wakes at San Juan Island.
A 5-6' series went under me at the cliff eddy in a strong incoming tide as I went back to Smallpox: coasting up down at 6-7 mph along the stonewall.
