What this video covers

James and Victoria visit Emerald Cave on Koh Mook Island, arriving by dinghy before 7 a.m. to beat the longtail-boat crowds and swimming through the cave entrance at high enough tide to enter.7:58 The cave delivers on the recommendation of a Danish sailor named Reese — abundant fish, warm water, and no other visitors.13:43 Afterward, Triteia departs on a 17-mile passage in light and variable conditions. Wind dies to near nothing at midday; James deploys a Rollie Tasker asymmetrical spinnaker to sustain 3 knots in roughly 7-knot air.17:53 When the wind clocks onto the nose, he starts the Honda outboard to motor the final 9 miles.18:46 He deliberately runs the top tank dry to measure fuel consumption — one hour at half throttle — but after refueling the engine bogs down under throttle and won't clear despite draining the float bowl, replacing the fuel filter, and letting it cool for 30 minutes.21:40 Pulling the spark plug cable and restarting with the fuel cap off finally clears the problem.30:09 Triteia anchors in 19 feet, setting 5:1 scope adjusted for a 7-foot tidal rise.31:33 A long-range tank fitting for the Honda remains unavailable; James plans to source one in Phuket and may switch to the Tohatsu as primary outboard in the meantime.20:34
