Important Information
Intended use
Raymarine H6 is intended for recreational marine use. Users should note that only
authorized government charts, publications and associated Notices to Mariners
contain all the information required for safe navigation.
The limits of electronic navigation
Experienced navigators know not to rely on a single method of navigation for
determining their position. Two or more methods should be used to determine
position and guard against errors placing you or your boat in a dangerous
position. Global Positioning System (GPS) based electronic navigation is an
amazing application of technology, but like all other technology, has its
limitations. A wise navigator will understand these limits and how they affect the
safety of their boat and its crew.
The GPS is made up of components starting with 24 satellites in orbit around the
earth. These satellites are monitored by ground based computers, which also
maintain the system. The system ends at your boat’s receiver. Like all systems, it is
not perfect and any part of it can fail. GPS accuracy varies between 2 and 50
meters.
Another limitation to accuracy of the system is digital charts. These electronic
charts are made by highly skilled cartographers. Surveys on which the
cartography is based, were in some cases, made over 50 years ago. So despite
everyone’s best efforts, it may be possible to have errors in the finished product.
The user should be aware that, in common with all similar products, tidal data is
calculated algorithmically and may in some regions, be subject to error. If exact
tidal heights or times are critical to a particular passage, it is recommended that
they be checked against a current Tidal Almanac published by the appropriate
marine authority.
Lastly, H6 software was developed by highly skilled and talented software
engineers and underwent a rigorous test and quality assurance program before
being released. However, it is possible that software issues or malfunctions may
remain undetected in the software. While Raymarine make every effort to find, fix
and repair software issues as they are discovered, this product is specifically not
promised to be issue free.
