With the iPhone becoming more and more an integral part of life for some people, I believed a list of helpful but low-cost apps for boating may be in order. All of these are either complimentary or just 99 cents at the time of writing.
Look around the chart title block at the many notes which contain navigation safety details. These tell you about vessel routes, threats, warnings, marine weather condition broadcast channels in the area, and offer essential cautionary information.

42 feet x 10% = 4.2 feet. Round this nautical charts approximately the next entire foot. 5 feet 42 feet = 47 feet fixed mast height. Write this down in your boat log for reference.

That implies when you outline the latitude and longitude from a nautical gps onto your chart, it will be accurate. If your chart reveals different datum info, you will require to set your gps to the suitable information (see your owner's manual). This resets the gps so analysing nautical charts that its lat and long matches the lat and long of the chart for error-free, accurate navigation.
The half-hull wreck sign reveals half of a black wedge with a stick-like mast on top. Keep your small cruising sailboat one mile or more far from these horrors.
Make certain to add equipment needed by Federal policies. Consist of individual flotation devices (pfd) for each individual; fire extinguishers that show a complete charge (gauge needle in the green location), emergency flares within the expiration duration, and required, existing paperwork. Remember that devices has to remain in good working order and can not have actually reached its expiration date (i.e. in the case of flares or boat documentation/registration/licenses, and so on). That way, you will be prepared if boarded by the Coast Guard.
These are just a handful of the beneficial cruising navigation chart signs you will find in Chart No. 1 or Chart 5011. Learn the most important ones to keep you and your cruising team safe on the waters of the world.
