THE TRAINING

Hands‑on coastal seamanship

Most of the course time is practical—two days on the water filled with drills and real‑world practice in docking, anchoring, sail trim, engine use and systems familiarization, all taught with safety as the priority.

THE SAFETY LENS

Safety first—prepare for weather and motion

Instructors emphasize safety throughout: students are advised to be well rested and hydrated, may consider motion‑sickness medication if prone, and the vessel will tie up at the nearest dock if a Special Marine Warning or an imminent thunderstorm threatens.

THE FORMAT

Blended classroom plus on‑water days

The course pairs a brief online classroom component with two full days sailing, so expect concentrated shore‑side instruction followed by extended on‑water application under instructor supervision.

What the day feels like

What the two‑day course feels like

This is a compact, skill‑forward course: a short online session lays the groundwork, then two long days aboard a keelboat push those concepts into practice—managing lines and sails, handling the auxiliary engine, navigating coastal waters and executing docking and anchoring maneuvers under instructor guidance.

Suitability

Who it's for

Sailors with some experienceIf you already have prior sailing experience you can opt to challenge the course standards on the water and sign up for a Challenge Course instead of the standard schedule.
3
Those prone to seasicknessParticipants who are susceptible to motion sickness should plan accordingly—consider over‑the‑counter medication and be prepared for full days aboard a moving vessel.
4
Physically prepared learnersThe days are active and long; students are advised to arrive well‑rested and hydrated and to wear closed‑toed shoes since you'll be handling lines and working on deck all day.
