RACING RULES OF SAILING
WHEN DO I USE THE JIB or THE GENOA ?
When the true wind speed, TWS > 25 kts, choose the jib (sail 1)
If TWS < 25 kts = genoa is us (sail 2)
However, some tracks have an average TWS ~ 23,5 to 24,6 kts, and when you enter a puff, TWS can easily reach 30+ kts, so you may need to switch from genoa to jib.
And in other circumtances, TWS average could be ~ 26,2 kts, so you would be sailing with the jib. But, it can occur that you would have to sail in an area where the TWS drops down way below 24 kts or even below 20 kts, then, switching from jib to genoa is definitively a must go.
WHEN DO I TACK (OR GYBE) IF THE WIND SHIFTS A COUPLE OF DEGREES ?
Most map makers do inform, either in the intro or directly in the name's track, the neutral wind observed at the start line and at the first mark, if it differs from the one noted at the start line.
It's familiarly called "MID".
Going UPWIND :
When : TWD > MID, the starboard tack will ensure to sail the course to the next mark in the most efficient way.
If the wind shifts and now : TWD < MID, you may prefer the port tack.
Of course, depending on your location, the angle of the leg versus the start line, distance to next mark, strength & direction of the current... you may want to revise/postpone the moment you will tack...
Going DOWNWIND, just invert what applies to the upwind.
BUT WHAT IF THE "MID" IS NOT PROVIDED ?
Dont panic :) looollll....
During pre-start period, go to the center of the start line,
point your bow straight to the 1st mark and note the HDG your instruments panel shows.
And VOOIIILLAAAAA, here you got your base...
Example : HDG you note = 12°
You know then, from now... when if TWD goes < 10°, the port tack is favorable to sail
(no other parameters taken...), but just a base...
