These training sessions will require short periods of moderate upper body exertion, and a moderate level of arm strength.  Participants will have the opportunity to experience sun, wind, spray, rain and temperatures consistent with the time of year they take part in this activity.  When underway the vessel may exhibit irregular motion due to wind and waves and temperatures may be cooler than on land.  Participants will be expected to learn and demonstrate skills and perform tasks while the vessel is at the dock, at anchor and when the vessel is underway.  In a day sailing format, vessels will be underway for varying periods of time (up to 8 hours), during daylight, in light to moderate wind and sea conditions.  These sessions are suitable for most fitness levels and will provide a good body core workout.
