2017 Seafair Log Boom Rules & Regulations

  • Log boom space for Seafair Weekend (the Albert Lee Appliance Cup Hydroplane Race and Boeing Seafair Air Show) will be guaranteed to credentialed log boom participants from 6:00 a.m. Friday, August 4, 2017 through 6:00 p.m. Sunday, August 6, 2017.
  • Credentialed boats must arrive by 11:30 a.m. at the west high rise of the I-90 Bridge and be tied to the log boom no later than 12:00 p.m. August 4 through August 6. See Seafair Notice to Boaters for complete information on lake closures. All boats must stay tied to the log boom until after the Blue Angels performance each day which is scheduled to be completed by 2:30 PM. Boat traffic is not allowed east of the log boom until after the Blue Angels’ performance.
  • Credentialed boats arriving after the Blue Angels fly must enter through the east high rise of I-90 Bridge or the south entrance, between Bailey Peninsula and Mercer Island. Boats proceeding to the white section only, must enter through the west high rise.
    All boats leaving the white section must leave the area through the west high rise only at a no wake speed; no transit is allowed through the north end of the course. All others may leave via the east high rise or the south end at a no wake speed.
  • With the exception of licensed charter boats, Coast Guard regulations prohibit boat owners from charging their guests a fee for use of their boat.
  • No shuttle boats allowed unless tied broadside with valid shuttle pass. One shuttle boat is allowed for each tied broadside boat to transport people to and from shore (Maximum 28 feet). Exit/entry in the morning is restricted to the west high rise only. No east/west travel will be allowed until after the Blue Angels performance. One additional shuttle boat pass (Maximum 24 feet) is available for an additional fee of $500 for broadside tied vessels only.
  • No rafting of non-paying vessels will be allowed, except in the broadside section where registered boats will be allowed to raft one shuttle boat. Seafair will install a barrier to keep non-registered boats away from the log boom.
  • Swimmers must be out of the water when the race boats are on the course. No diving from boats. Inflatable devices must be smaller than 3 feet and hold no more than one person. No trampolines or islands. Seafair can revoke your opportunity to use any flotation devices. Swimmers/floaters must stay within 6 feet of their own vessel.
  • Absolutely no drones are allowed from 6:00 a.m. Thursday, August 3 through 6:00 p.m. Sunday, August 6. Anyone caught flying a drone during these hours will have their credentials revoked and will be removed from the log boom and drone will be confiscated. Due to FAA regulations, no kites or helium balloons will be allowed.
  • Absolutely no water balloon launchers, water guns, or cannons will be allowed. Boaters caught launching water balloons will have their credentials revoked and will be removed from the log boom.
  • Upon arrival, stern tie vessels will tie directly next to the beam of existing tied vessels. Broadsiders will make best bow to stern moorage. Spots in any section except the Blue Section may not be reserved. Boats may be shifted, first come first served.
  • Vessels on the log boom must be manned at all times with a person capable of operating the vessel. 

  • Only motorized boats, except for WN registered sailboats, will be accepted. All boats must have manufactured hulls. No rafts or inflatables are allowed to tie up to the log boom.
  • Seafair Patrol Volunteers, with the support of the U.S. Coast Guard, Seattle Harbor Patrol, and King County Marine Patrol, are authorized to revoke credentials and remove non-complying boats from the log boom.
  • No commercial banners/flags are permitted on participating boats without written authorization from Seafair.
  • Absolutely no radio broadcast or use of a radar is allowed from the log boom without written pre-authorization from Seafair. Boats violating this rule will be removed from the log boom immediately.
  • Skippers of all boats on the log boom are responsible for the conduct of their guests at all times; they will have their credentials revoked for any lewd or illegal conduct and will be removed from the log boom.
  • In rare instances, an individual section of the log boom may be oversold because spectator boats are larger than registered or not moored closely together. In these instances, Seafair reserves the right to move spectator boats to sections of the log boom other than originally requested by the spectator. Seafair recommends that spectator boats arrive early in the day to avoid this inconvenience.
  • In the event of high wind conditions (in excess of 10-15 knots), at Seafair’s discretion, some broadside tied boats may be asked to rotate to a stern tie position. In an emergency, Seafair may need to cut ties.
  • Anything attached must be removed. Must clean up own trash.
  • Refund Policy: We are unable to offer refunds. Seafair Weekend Festival continues rain or shine, except in extreme or dangerous weather conditions.
