Universal Masthead Mount

INSTRUCTIONS

The Davis Universal Masthead mount helps sailors gain space aloft and improve mounting

position of wind finders and other equipment. The mount adapts to virtually every masthead

situation; includes all necessary hardware to attach securely to flat, curved, vertical, horizon-

tal, or inclined surfaces. Some typical uses:

Extending a wind indicator aft of

the mast for better visibility.

Mounting a wind indicator clear of

VHF antennas, lights, or other

installations.

Mounting other accessories such

as wind velocity sensors away

from mast turbulence.
