Set Custom Gybe Angle (TWA)
💡 Downwind VMG: Sailing dead downwind (180° TWA) in a Flying Scot is slow because the Apparent Wind drops. Heating up the angle (sailing at ~142° TWA) builds Apparent Wind, which speeds the boat up enough to cover the extra distance faster.
Active Wind: 10.0 MPH @ 0°
Target True Wind Angle (TWA): 142.2°
Target Boat Speed: 5.3 MPH
Downwind VMG: 4.2 MPH
Starboard Gybe Heading: 142°
Port Gybe Heading: 218°

⛵ Flying Scot Mast Rake & Rig Tuning Guide

The Flying Scot utilizes a stayed fractional rig with swept spreaders and a tabernacle mast step (no backstay or partner chocks). Rake and tension adjustments control helm and sail shape:

1. Mast Rake (Standard 28' 4 1/2" - 28' 6", User 28' 3"): Rake is measured from the masthead to the center of the transom. Raking aft (e.g. your 28' 3" setting) shifts the sail's center of effort aft, generating desirable **weather helm** upwind. This creates lift on the rudder to help point higher. Raking forward reduces helm pressure, ideal for acceleration and heavy breeze. 2. Rig Tension (Jib Halyard / Shroud Tension): Shrouds should be snugged (70-80 lbs in light air to 110-120 lbs in heavy air). Snug shroud tension prevents the headstay from sagging, which flattens the jib entry to allow pointing closer upwind. Letting the headstay sag (looser rig) rounds the jib entry for extra power in light air or chop. 3. Upwind Vang Sheeting: In heavy breeze, pull the vang tight. This bends the lower mast (flattening the main) and holds the boom down, allowing the mainsheet to be eased in gusts without the boom rising.
