I own Mustang (daft name for a Seahawk 17 but not my choice) which sails in Lyme Bay and the Camel estuary. Your boat is as Greg says very rare with the green hull. I would call her just "Mallard" as she is green! I brought my boat back from the dead by dealing with a very crazed gel coat, a jammed keel, baggy sails and leaking crazed windows. She now looks very smart and sails very well for a 17' boat - saw off several Shrimpers this year on the Camel! Happy to help with rigging, restoring, etc. although most info is on this site thanks to Greg's stirling efforts.
