Calibration What a title to kick off!- Focus on raw sensors- Pay a pro to get it done if you cant

find the time

winning

winningCalibration• Depth

• Compass

• Speed

SEATRACK CALIBRATIONEXAMPLE

• AWA (or MWA)

• Focus on core sensors• Keep notes

• Depth– At the dock

• Compass– Check compass mountings &

position– Stow– Calibrate

• Speed– Shorter distance if it gets it done– Check sensor alignment– Check sensor for growth

• AWA– Tack to tack – Negative is to port

winning

Preparation• Entry• Waypoint management (winningtides.co.uk)• Weather sources• Communication to crew• Sailing instructions (check list in wet notes)• Tools of the trade (and bring list)

marker pens, hand held compass, waterproof pad, rule book, SI’s laminated, watch and spare, tide books, knowledge book, HW table, waterproofs, weather forecast two sources, back up GPS, spare batteries, spare pencil, knife, nav bag, hat, sunglasses, sun cream, money, phone with WAP, (THIS MUST ALL WEIGH ZERO), binoculars, plastic zip bag, pvc tape, head torch, VHF, life jacket.

buoy chart and passed to crew (you may need a helper for this)

• Line bias EXAMPLE FROM SEATRACK• Relevant time to line (acceleration table)• How to call the time in the last 1.30 mins• PHYSICAL POSITION…

– Stand next to tactician until start then hike hard near their ear

Racing– Relevant time to line (acceleration table)– Splits to first mark EXAMPLE FROM SEATRACK when to communicate it– Next leg data EXAMPLE FROM SEATRACK– TWD over 10mins– Sail crossovers inc next leg EXAMPLE FROM SEATRACK– Approaching first mark TWD which phase its in with Splits– Finial layline in to an inflatable buoy

• Physical position – hike next to tactician
