More about VHF

VHF (Very High Frequency) radios serve as the primary communication tool for most vessels, facilitating contact with other boats, bridge operators, lock personnel, harbormasters, towing services, and emergency responders such as the Coast Guard. Following life jackets, a VHF radio ranks among the most critical safety equipment on a boat. Many experts recommend having both a fixed-mount and a handheld VHF radio on board. VHF radio signals operate on a "line of sight" principle, meaning that obstacles like islands, large waves, or the earth's curvature can obstruct transmissions.

Consequently, the height of the radio's antenna significantly influences its transmission range more than the power output. A key feature to consider in both handheld and fixed-mount VHF radios is Digital Selective Calling (DSC). In emergency situations, a DSC-enabled VHF radio allows for the transmission of a distress signal that includes precise location details along with essential information such as the vessel's name and type. Many DSC-enabled VHF radios come with integrated GPS, while those without require a connection to an external GPS device.

Handheld VHFs

Handheld VHF radios offer boaters a means of short-range portable communication. They are commonly utilized for ship-to-ship and ship-to-shore communications, as well as for relaying vessel traffic information and facilitating communication between a dinghy and the main vessel. These radios typically have a maximum transmitting power of 6 watts, with an effective range often restricted to approximately 3 to 5 miles, primarily due to the lower antenna height associated with typical usage scenarios, such as when operating from a dinghy or while on deck. When selecting a handheld VHF radio, it is essential to consider factors such as battery type, battery life, waterproof capabilities, screen size, and warranty.

Fixed-Mount VHFs

Fixed-mount VHF radios are equipped with a transmitter power of 25 watts, with the capability to transmit at a reduced power of 1 watt, minimizing the risk of interference with nearby vessels during short-range communications. It is advisable to attempt contact using 1 watt before increasing to 25 watts.

In contrast to handheld radios, which typically have a range of 3 to 5 miles, fixed-mount VHF radios can achieve a range of 5 to 25 miles, primarily influenced by the height of the antenna rather than the power output. VHF antennas are sold separately, with powerboats generally utilizing antennas ranging from 6 to 23 feet in length. Sailboats often position their VHF antennas at the top of the mast, significantly enhancing their communication range. Some fixed-mount VHF radios also feature an integrated AIS transceiver, which allows users to monitor the position, course, and speed of other AIS-equipped vessels, thereby improving collision avoidance capabilities.

More About Fishfinders

Fishfinders provide a visual depiction of underwater features beneath the boat, such as depth, bottom composition, vegetation, and fish. Many modern fishfinders are equipped with CHIRP technology, which stands for Compressed High-Intensity Radiated Pulse, offering exceptionally detailed images of both fish and underwater structures. When selecting a fishfinder, important factors to consider include screen size, power, and screen resolution. Most fishfinders available at Suncoast Marine come with a transom-mount transducer.

More About GPS/Fishfinder Combos

Combo displays integrate a chartplotter and fishfinder into a single unit. They typically include a built-in internal GPS antenna, which is effective for installations above deck. However, for below-deck installations, it is advisable to acquire a separate GPS antenna that can be mounted above deck to ensure an unobstructed view of the sky.

Many combo units, particularly those designed for small-boat inland fishing, are equipped with a transom-mount transducer. For other applications, compatible transducers such as:

When selecting a combo unit, important features to evaluate include screen size, screen resolution, available cartography, and the transmitting power of the fishfinder.

More About Radars

Radar represents the most effective collision avoidance system available for boats. It allows operators to detect obstacles in low visibility conditions such as darkness, fog, and storms. Modern solid-state radar systems are designed to be compact, energy-efficient, and suitable for vessels as small as 18 feet. When integrated with AIS and an electronic chartplotter featuring digital charts, radar significantly enhances navigational safety.
