The Treasure Island Sailing Center (TISC) Open Sailing Program provides an opportunity for the TISC community to come out and enjoy the bay.

Skill Level Certifications

Each sailor receives a certification level based on their sailing skill and experience. For each level, the sailor must pass a rigging and an on-the-water practical. These skill levels determine a sailor’s permitted sailing area and wind conditions. 

  • Crew  – Crew on all sailboats with higher level skipper
  • Level 1 – Skippering up to 10 knots
  • Level 2 – Skippering up to 16 knots
  • Level 3 – Skippering up to 20 knots

Please Note: The skipper of the boat determines the certification level needed for the wind conditions. Novice sailors are allowed to crew as long as the skipper of the boat has the proper certification level needed. Paddle Sports are available for everyone regardless of wind speed up to 16 knots of wind. 

Certification Assessments: Initially, each sailor is given an Intro Level Certification. Once a sailor is prepared to achieve a new certification level, he or she must schedule a certification assessment. The first attempt to achieve a new level is free – Any additional attempts will incur a $10 fee. To advance to the following level, the wind speed must be above your current level’s maximum. 

Safety Limitations

To ensure the highest standards of safety, the following limitations are in effect.

Sailing Conditions: Each sailor’s permitted sailing conditions are directly related to the wind speeds and his/her certification level. Wind speeds are indicated by a flag on the pier flag pole. 

  • Green – Light winds up to 10 knots – Level 1 skipper and above
  • Yellow – Moderate winds up to 16 knots – Restricted use, Level 2 skipper and above
  • Orange– Strong winds up to 20 knots – Restricted use, Level 3 only, No watersports equipment
  • Red – Strong winds 22+ – No sailing

Please Note: If the wind flag is dropped, no boats can leave the facility and all boats must return to shore.

Sailing Areas: TISC has two sailing areas. The highest level skipper onboard dictates which areas the sailors are allowed to sail. Watersports equipment (kayaks, paddleboards, windsurfers) are only allowed in Sailing Area 1.

  • Sailing Area 1: All watersports equipment and sailboats skippered by sailors with a Level 1 certification. Limit line is from the end of the TISC Launch Ramp, straight across the cove.
  • Sailing Area 2+: For sailboats with sailors with Levels 2 and 3 certifications only. From the end of the pier straight to the bridge

Before You Sail

Reservations: Reservations are recommended for sailing or watersports. If there are no reservations for a particular time, the facility may close and an attendant may not be onsite. If a sailor makes a reservation and does not attend they will be sent a warning.  If they fail to show up for a reserved time, they will incur a $10 fine.

Drop ins: Drop ins are available, although we recommend reservations. If there are no current reservations scheduled our staff may be assigned to other activities and the facility would not be available for open sailing. 

Guests: Sailors are encouraged to bring guests to our community sailing center. 

Medical and Liability Release: Each person needs a signed medical and liability form. Youth under the age of 18 must have a parent signed medical and liability form in order to participate. NO ONE IS ALLOWED ON THE WATER WITHOUT A COMPLETED MEDICAL AND LIABILITY FORM.

While You Sail

Facility Sign In/ Sign Out: To ensure safety at our facility, all participants must sign in with the office or with the waterfront coordinator when arriving at the facility and sign out when finished sailing. YOU ARE RESPONSIBLE FOR ANY DAMAGE NOT PREVIOUSLY REPORTED.

Required Gear:

  • Life Jackets (PFDs) – Life jackets are always required at all times on the pier, docks and in the boats for everyone! NO EXCEPTIONS! TISC has life jackets available at no cost.
  • Wetsuits – Wetsuits are available for use and are required for youth under the age of 18. Please note that the water is cold and TISC recommends use of a wetsuit at all times.
  • Footwear – Rubber soled, close toed shoes must be worn at all times on the boats and in the yard.
  • Safety Whistle – The skipper of each boat must have a whistle attached to his/her life jacket. The attendant will monitor the water for signs of distress.

Avoidance of Obstacles: Sailors must stay 3 boat lengths away from other boats and marker buoys and 5 boat lengths from the shore and docks, except when returning to TISC. With advanced permission of the attendant, boats may be taken to the beach at the west end of Clipper Cove. The sailors are not allowed to dock with other boats, at the TI Marina or any other facility unless under distress.

Emergency Action Plan: TISC has an easy to follow plan in case of large scale emergencies including natural disasters. This plan is required to be read once joining the program. Extra copies of this plan are stored in the Pier Classroom and are available to anyone that would like to review.

Signal Flags: All sailors must be aware of and monitor the TISC signal flags at all times. If the signal flags are lowered, all sailors must return to the dock immediately. Lowering of the flags may be accompanied by three long blasts of a signal horn.

Safety Boat: One safety boat will be in the water at all times with an attendant ready to assist. Please note:  No boats will be checked in or out if the attendant is engaged in an assisted rescue. 

Check In: Each boat must check in with the attendant when returning to the facility. If there has been damage, it must be reported immediately. If there is no reservation for the equipment, the sailors must pull the boat from the water and wash it. 

After You Sail

Equipment Upkeep: All boats must be launched, pulled and cleaned by the user unless it is being passed off to a group that has a reservation afterwards. All equipment such as life jackets, wetsuits, sails and blades must be cleaned and returned to their storage area after use.

Damage and Repairs: Any damage that has occurred while using the equipment must be reported to the on-site attendant. The attendant is responsible for evaluating the equipment and will determine if the equipment can still be used or not. Sailors are responsible for any costs associated with repairing the damages other than normal wear and tear. YOU ARE RESPONSIBLE FOR ANY DAMAGE NOT PREVIOUSLY REPORTED.
