Benefits of technology

[0005] (2) To increase the fuel efficiency of vessels by reducing crustacean attachment to their hulls.
[0007] (4) To increase the useful lifetime of vessel hulls.
[0008] (5) To provide a method of implementing the above features consistent with low cost and implementation on a variety of vessels.
[0014] FIG. 7 (0700) illustrates a typical and preferred mesh weave that is effective in permitting water transfer but simultaneously preventing crustacean entry.

Problems solved by technology

It is well known in the art that crustaceans (barnacles, etc.) attach to the hulls of all seagoing vessels, causing damage to the hulls, reducing the fuel efficiency of the vessels, and eventually result in increased maintenance costs.
The art has not as yet devised a simple and inexpensive method of combating this problem.

generic embodiment (

0400)

[0037] The present invention may be embodied in generic configurations as illustrated in FIG. 4 (0400) in which the mesh material is generally constructed to be rectangular with a multiplicity of tie points (0410) for attachment to the vessel. This generic formulation permits one configuration to service a number of vessel hulls.

Box Embodiment (0500)

[0038] The present invention may be embodied in box configurations as illustrated in FIG. 5 (0500) in which the mesh material is generally constructed to be in rectangular box form with a multiplicity of tie points for attachment to the vessel. This rectangular box formulation permits one configuration to service a number of vessel hulls with a variety of draft sizes.

[0039] Note here that the configuration illustrated in FIG. 5 (0500) is constructed for a vessel having dimensions of 12-feet by 32-feet with a draft not to exceed four feet. One skilled in the art will recognize that this template may be altered to service a large numb...

Exemplary Method Embodiment (1400)

[0055] The general installation / removal method for the present invention is generally illustrated in FIG. 14 (1400) and includes the following steps:

[0056] 1. Grasp the rope on the end of the barrier mesh and tie the nylon rope to the cleat or other fastener on the bow of the boat (1401);

[0057] 2. While holding the back corner of the barrier, place the rest of the barrier into the water and pull the barrier to the back (stern) of the boat, dragging the entire barrier under the hull (1402);

[0058] 3. Pull the barrier above the waterline of the hull and tie the ropes to the cleats or other fasteners on the back of the boat in each corner (1403);

[0059] 4. Travel towards the bow of the boat pulling the barrier above the waterline and tie the ropes to the cleats or other fasteners along the side of the boat (1404);

[0060] 5. Repeat steps 2-4 for both sides of the boat until all of the ropes are secured to the cleats and the barrier is above the waterline a...

Abstract

A crustacean barrier system and method incorporating a woven polyolefin and / or polymer mesh covering the hull of a protected vessel above the waterline is disclosed. The present invention permits a woven mesh to be deployed below the waterline on a boat or other seagoing vessel and is secured to the boat via the use of nylon straps and / or cleats. This mesh creates a barrier to crustaceans and prevents their attachment to the vessel hull. An alternative embodiment is disclosed that utilizes floatation cylinders to support the woven mesh at a level necessary to encompass the draft of the boat / vessel hull. These disclosed systems and method prevent crustaceans from attaching to the vessel hull, improves fuel efficiency of the vessel, reduces vessel hull maintenance, and extends the life of the vessel hull.

Description

[0001] The present invention is related directly to situations in which seagoing vessels must be protected from crustaceans (barnacles, etc.) as these creatures reduce the fuel efficiency of vessels, increase the need for hull maintenance, and reduce the life of vessel hulls.[0002] It is well known in the art that crustaceans (barnacles, etc.) attach to the hulls of all seagoing vessels, causing damage to the hulls, reducing the fuel efficiency of the vessels, and eventually result in increased maintenance costs. The art has not as yet devised a simple and inexpensive method of combating this problem.OBJECTIVES OF THE INVENTION[0003] Accordingly, the objectives of the present invention are (among others) to circumvent the deficiencies in the prior art and affect the following objectives:[0004] (1) To provide a system and method restricting the attachment of crustaceans and the like to vessel hulls.[0005] (2) To increase the fuel efficiency of vessels by reducing crustacean attachmen...
