Abstract

Abstract A portable, safety hull cover for a marine vessel or the like which may be quickly deployed from a vessel which has sustained hull damage that destroys the water-tight integrity of the hull which could cause the vessel to flood and ultimately sink. The saftety cover is a flexible, waterproof sheet of material sized and shaped for attachably conforming to the vessel bow, sides and keel, with the cover being readily connected to the bow by an attaching noose and deployed against the hull along the outside bottom of the vessel. The safety cover when deployed will prevent water from being received into the boat through a damaged hull section as long as the boat or vessel is moving, such as would be the case with the vessel trying to reach a safe harbor. The device has an auxiliary use to form an enclosure around the boat for cleaning the hull.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 162 words
A safety cover for deployment with a marine vessel which has sustained hull damage to prevent water damage from leaking into the vessel allowing the vessel to be moved with hull damage to a safe location comprising: a flexible, waterproof thin sheet, said sheet being shaped and sized to cover the hull of a vessel, said sheet having a forward edge having a connector portion for receiving a rope or line; a plurality of fastening means disposed along the edges and connected to said cover for attaching the cover to the hull of a vessel; a boat stern end fastening means connected to the end edge portion of said flexible sheet; a pair of elongated lines connected to the stern end portion of the cover, said lines being sized to be substantially the length of a particular vessel; and said sheet having a large, reinforced aperture disposed adjacent the stern end of the sheet for receiving the drive shaft of the propeller.
