This is the route Sigal would sail. Seven days, six nights aboard, starting and ending at Salak Phet (Island Spirit Yacht Charter base), heading south through the cluster to Koh Kut, looping back through Koh Rang Marine Park. Built around the NE-monsoon wind direction (Nov-Mar prevailing) so every overnight is in protected water · daylight-only sailing (sunset ~17:45 · anchored by 16:00) · plenty of slack time at the anchorages because this is not a delivery, it’s a holiday. If you have 10 days, add 1 night each at Koh Mak, Koh Rang, and Koh Kut. If you have 14 days, slow everything down.
