Abstract: A method of using a system to apply liquid over a selected area includes providing a source of liquid, a first tube for transporting liquid from the source through the system, a connector, a check valve and a spray device. The connector includes a projection extending into the first tube. The projection has an inlet in fluid communication with the first tube. The connector further includes an outlet and a passageway in fluid communication with the inlet of the projection and the outlet of the connector. The check valve has an inlet in fluid communication with the outlet of the connector and an outlet. The check valve is operable to permit the passage of liquid from the inlet to the outlet upon pressurization of the liquid above a threshold pressurization level.

Abstract: An apparatus for dousing a spinnaker sail on a sailboat. The apparatus can include a remote releasable line lock device attached to a lower portion of the spinnaker. A retrieval line for dousing the spinnaker can pass through the remote releasable line lock device and can be attached to an upper portion of the spinnaker. The remote releasable line lock device can include a housing having two cams with at least one cam being movable and biased toward the second cam and positioned to grip the retrieval line. The movable cam can have a cam actuator extending through the sidewall of the housing and can move the movable cam away from the second cam to release the retrieval line. A remote release device can be provided to operate the cam actuator and release the retrieval line when the remote releasable line lock device is positioned in the remote release device.
