[Pilot Chart, Hydrographic Office.]

"Rule 1. - If the squalls freshen without any shift of wind, you are on or near the storm track: heave to on the starboard tack and watch for some indications of a shift, observing the low clouds particularly, if the barometer fall decidedly (say half an inch) without any shift, and if wind and sea permit, run off with the wind on the starboard quarter and keep your compass course.

"Rule 2. - If the wind shift to the right, you are to the right of the storm track, put the ship on the starboard tack and make as much headway as possible until obliged to lie-to (starboard tack).

"Rule 3. - If the wind shift to the left, you are to the left of the storm track: bring the wind on the starboard quarter and keep your compass course if obliged to lie-to, do so on the port tack.

"General Rules, Good for all Northern Hemisphere Storms. - In scudding always keep the wind well on the starboard quarter, in order to run out of the storm. Always lie-to on the coming-up tack. Use oil to prevent heavy seas from breaking on board."
