Last Thursday around 830 pm, Fireboat 8 was alerted to assist Fairfax County with a search for two missing kayakers. The kayakers had last been see approximately 30 hours before our boat was requested. Fireboat 8 responded with a crew of 5. After initially checking the Potomac River south to the power lines, the crew then headed north to search along the Maryland shore. The crew then checked Craney Island, which is just north of the Potomac Heights area. Upon approach of the island, our crew spotted two victims waving frantically from a duck blind. The victims were placed on Fireboat 8 and checked for injuries. After ensuring no injuries or major medical concerns, the victims were transported to Fireboat 420 (Fairfax) who then took them back to the Virginia shore where their trip started. Our crew returned to quarters at approximately 1AM.
