Benefits of technology

[0024] It is also an object of the present invention to provide for such a system, which minimizes surgical incision, and wholesale removal of large sections of the outer fiberglass skin of a boat hull.
[0043] The methods of this invention are intended to identify and repair all wet core hull areas and to perform preventive maintenance on dry hull areas to restore the integrity of a fiberglass boat hull and to prevent new water infiltration damage beyond the level of a new hull.

Problems solved by technology

In early stages of moisture attack, only sporadic regions and spots on the boat are damaged.

Embodiment Construction

[0088] The present invention has broad applications to many technical fields for a variety of articles. For illustrative purposes only, a preferred mode for carrying out the invention is described herein, wherein a repair system for treating boat hulls with rotted balsa wood cores utilizes a minimally invasive incision and treatment technique of the fiberglass boat hull.

[0089] As shown in FIG. 1, in a prior art boat hull repair method, a major portion of boat hull 1 with a large part of the fiberglass skin 3 is peeled away from fiberglass skin 2, revealing the damaged areas 5 of the balsa wood core of hull portion 4 to be treated and removed.

[0090] In contrast, in the present invention, general areas 5 of moisture damage to a boat hull 1 are determined by exposing the exterior surface of a boat hull 1 to a moisture detector 8, such as a moisture meter as shown in FIG. 1A, or by other moisture sensing equipment, such as a thermal or infra-red camera. A typical moisture meter 8 has ...

Abstract

A method for preventive maintenance of a boat hull to restore the integrity of a fiberglass boat hull and prevent new water infiltration damage to a boat hull. The wet area repair guidelines using a surface moisture meter. Any balsa cored area reading 15% or above is considered a wet area. Any wood cored area reading 20% or above is considered a wet area. The preventive maintenance steps involve removing all through-hull fittings or hardware. Wet core areas are then dried out using heat lamps, lights or heaters, hot-vac systems, or octopus vacuum with grid system. If necessary, any area not drying out is de-cored and repaired accordingly. After repairs are finished, all through-hull fillings or hardware is reinstalled using new sealant.

Description

RELATED APPLICATIONS [0001] This application is a continuation of application Ser. No. 10 / 857,834, filed Jun. 2, 2004 and claims priority under 35 U.S.C. 120 therefrom. This application is incorporated by reference herein.FIELD OF THE INVENTION [0002] The present invention relates to prevention of water damage to balsa wood cores of fiberglass boat hulls. BACKGROUND OF THE INVENTION [0003] Fiberglass boats are typically constructed using an inner and outer fiberglass skin separated by a balsa wood core. The balsa wood core is in the form of small separate blocks preattached to a fabric or fabric like material mesh on one side only. This allows the separate blocks to tilt in two directions relative to each other to readily follow the convex contours of a boat. The spaces between the separate blocks are called veins. [0004] While the balsa wood is very light weight and offers adequate crush resistance (on end grain), it is quite vulnerable to water infiltration between the fiberglass ...
