Yacht barnacle inhibitor system

a technology of anti-fouling paint and inhibitory system, which is applied in the direction of hulls, vessel cleaning, vessel construction, etc., can solve the problems of reducing maneuverability and speed per unit of fuel used, dragging on the vessel, and significant increase in surface roughness of the hull known as fouling, so as to reduce the frequency of in-water scraping, reduce the reliance on anti-fouling paint, and reduce the frequency of dry-dock scraping

Benefits of technology

[0021] reduced reliance on anti-fouling paint;
[0022] reduced frequency of dry-dock scrapi

Problems solved by technology

When these marine organisms grow on the hulls of marine vessels, the result is a significant increase in the surface roughness of the hulls known as fouling.
Fouling creates drag on the vessels that reduces maneuverability and speed per unit of fuel used.
Fouling also increases overall fuel costs and reduces operational time at sea during dry dock maintenance.
The downside to TBT is that in waters contaminated with the antifouling agent, whelks were starting to show sex-changing disorders, and oysters developed abnormally thick shells.
Although these mixtures work well in the short term, the best formulations only last up to three years and do not match the five-year lifetime of the self-polishing TBT coating.
Therefore,

Embodiment Construction

[0038] The numerous innovative teachings of the present application will be described with particular reference to the presently preferred embodiment (by way of example, and not of limitation).

[0039] Since nitrogen bubbling has been shown to deplete oxygen content in bilge water and thereby reduce mollusk growth, the present application teaches that nitrogen bubbled through a soft porous hose along the underside of a boat at a quiet slip where it spends most of the time, will inhibit barnacle growth.

[0040] A porous hose such as a lawn soaker hose can easily be placed on one or both sides of a boat while it is in a slip. This hose could be hooked over the transom and then tied to the bow such that it would lie near the keel. Typically, this is done on both sides of the boat to assure coverage. The porous portion only begins below the water line.

[0041] The hose material is preferably made of a fabric or soft rubber such that if the boat was started up by accident while the hose was...

Abstract

A defouling system for pleasure yachts and the like. An oxygen-depleting gas is bubbled into the water in close proximity to the hull. Various barriers in the water can be positioned to reduce diffusion of oxygen to the hull surface.

Description

CROSS-REFERENCE TO OTHER APPLICATION [0001] This application claims priority from 60 / 515,203 filed Oct. 28, 2003, which is hereby incorporated by reference.BACKGROUND AND SUMMARY OF THE INVENTION [0002] The present invention relates to systems and methods for controlling fouling, i.e. the growth of aquatic fauna (such as barnacles) on the wetted surfaces of ships and boats. [0003] Background: Barnacles and Fouling [0004] Barnacles, mussels, and algae have evolved to thrive underwater on the surfaces of rocks and in crevices. When these marine organisms grow on the hulls of marine vessels, the result is a significant increase in the surface roughness of the hulls known as fouling. Fouling creates drag on the vessels that reduces maneuverability and speed per unit of fuel used. Fouling also increases overall fuel costs and reduces operational time at sea during dry dock maintenance. [0005] The traditional remedy has been a regular visit to the dry dock where barnacles and other organi...
