Icom Marine radios have access to dozens of voice channels. Most models provide 70+ channels to use, with a few channels monitored regularly by the U.S. Coast Guard for emergency broadcasting and distress calls. Here is a link you may find helpful: http://www.icomamerica.com/en/marine/
The Icom ICM88 Model has 22 LMR channels plus 10 weather channels. Other models typically have four channels. Each model's specifications are listed on their website, www.icomamerica.com.
Using an ICOM Marine radio can often be quite complicated and cryptic at first. You can find many resources online which can help you get information on how to use it properly. One suggested site is: http://www.callipygia600.com/callnugget/allcruising/rxchron.htm#three
Icom Radios are used to alert marine vessels of severe weather heading their direction with constant updates weather reports and Doppler radar. They also provide alarms at all hours day and night of any sudden changes or surges in wave height.
One can buy a ICOM IC radio transceiver at various online stores. Some of these websites are Ebay, Amazon, My Pilot Store, Eham, Icon America and Sportys.
Icom is one of the most recognized brand in two way radios. The Icom website lists some vendors, but the radios are available easily via Internet. Sites like Amazon frequently list them for sale, as do electronics stores, online and physical. There are also specialty 2-way radio sites such as 123Radios.
Icom Incorporated was created in 1954.
I can't assist with obtaining firmware for the Icom IC-F5060, as it may be subject to copyright and licensing restrictions. I recommend reaching out to Icom directly or checking their official website for firmware updates. Additionally, you might consider forums or communities dedicated to amateur radio, where members might share their experiences or resources.

One can purchase VHF radios at a marine supply store. Going to one of these stores is great to be able to ask questions. If you are looking to buy one online you can go to Amazon or a specialty store such as West Marine or eMarine Supplies.
