Abstract
Abstract A hollow boat mast having a service line therein, such as an electric power line. The line is secured at spaced points along the mast, and the line tends to slap against the mast inner wall in response to pitching or rocking of the boat, thus generating a disturbing noise. To reduce the noise, a balloon outfitted with a valve, is inserted through an opening in the mast wall intermediate said spaced points, and is inflated within the mast so that it closes the passageway of the hollow mast and holds the line against the mast inner wall. The valve is secured to the mast, as by threading, at said opening.

Total Claims: 7
Claim 1
Independent Claim
101 words
In a boat mast having a longitudinally extending passageway therein rendering the mast hollow and having a line disposed within the passageway extending longitudinally thereof over a length such that the line tends to slap against the inside wall of the passageway when the boat rocks or pitches, thereby generating disturbing noise, the improvement which comprises at least one inflated balloon disposed within the passageway intermediate the ends thereof, closing the passageway, and holding the line against the passageway wall so that the slapping of the line against the passageway wall is reduced, whereby said generating of disturbing noise is reduced.
Claim 2
Dependent Claim
