Patent ID: 7500441

Claim:
A floating semi-submersible self-powered device small and light enough to be carried by an average man having means of removing unclean substances from waterlines on floating vessels, comprising: (a) a floating body carriage having propulsion means mounted there under for powering said body carriage to move through a fluid, (b) an engine mounted to an aluminum frame attached to said carriage for producing rotational energy, and (c) means for controllably coupling rotational energy from said engine to a revolving shaft with spiral blades that creates a forward or backwards thrust, whereby said carriage will be propelled along said fluid, and (d) means for directing said thrust left or right, whereby said carriage will turn when signaled from a remote control as it is propelled, and (e) means for having a side propulsion, whereby said carriage can move in a sideways motion in said fluid when signaled from said remote control, enabling said body to circumvent the floating vessel's waterline being cleaned, and (f) wherein said body includes means of applying a cleansing agent and a rinsing fluid to waterlines on a floating vessel's hull, and (g) wherein said cleansing agent is stored in a container attached to said body carriage.
