Mariner protects our customers with two separate warranties:
Master-Mariner does not warranty our product against direct weather exposure i.e. direct rain or snow or seawater. We suggest you mount your instruments in an area that is sheltered against the elements. On your patio, you may find a nice roof overhang to shield your new instruments from direct weather. On your boat, below decks is preferred to outside, or if mounted on an outside deck area, under shelter.
We also suggest, for greater accuracy, to mount the instruments out of direct sunlight or your Master-Mariner thermometer may read a higher temperature than the actual ambient temperature.
The Windlass Set instruments weigh approximately 22 ounces each and the Cabin Set instruments weigh 18 ounces each.
Master-Mariner provides an extra T-bar in every Gift box set, or three T-Bars for two instruments! We understand anyone can make a mistake. For this same reason we provide extra screws in your gift box. In the future, we will have T-Bars available for purchase on our website.
Master-Mariner uses the very highest quality coil spring hygrometer and thermometer movements in our products. Please refer to our product service page to test and calibrate your instruments.
Master-Mariner offers single and double hardwood cradles for your Gift Sets. These are constructed American Walnut or American Pecan in 3 different finishes. We also have hardwood wall plaques in attractive finishes to match your home or boat.
No. Master-Mariner does not harm any animals to produce our product line. Our wood cradles are also not real mahogany to comply with the CITES agreement on endangered wood species.
