Why Essential Marine Hardware Matters for Offshore Sailing
Offshore sailing demands careful equipment choices. Essential marine hardware for offshore sailing supports preparation for challenging conditions.
Offshore conditions can put equipment to the test. Lines, fittings, and communication systems are among the components sailors may consider when preparing a vessel.
This guide covers categories of marine hardware and considerations for offshore sailing.
Below, we'll cover personal safety systems, distress signaling, navigation and communications, rigging, spare parts, and maintenance considerations.
Personal Safety Equipment: Lifejackets and Personal Flotation Devices
Lifejackets and personal flotation devices are among the equipment sailors may consider for offshore sailing.
The Mustang Atlas 190 DLX Open Ocean Inflatable PFD has 190N of buoyancy, an integrated spray hood, and a SOLAS-approved water-activated light.
Emergency Location and Distress Signaling: EPIRB and Survival Gear
An EPIRB, or Emergency Position-Indicating Radio Beacon, is a distress-signaling device. The ACR GlobalFix V6 listing describes its 406 MHz distress transmission and worldwide Cospas-Sarsat search-and-rescue satellite network.
The ACR GlobalFix V6 Category 2 EPIRB transmits on 406 MHz, derives position through GNSS networks, and provides position accuracy to within 100 meters. It also transmits a 121.5 MHz homing signal and features Return Link Service, which confirms that the distress message was received.
The GlobalFix V6 uses Near Field Communication to connect to a smartphone for diagnostics that demonstrate whether the battery is charged and the EPIRB is functioning correctly.
The ACR RapidDitch Bag is made of water-resistant, reflective material and floats with up to 25 pounds of gear. Its shoulder strap transforms into two 4-foot safety harnesses, and an external pocket allows access to an EPIRB. The bag can be customized with survival equipment for sailing or boating conditions.
Communications and Navigation: VHF Radio, Compass, and Autopilot
The Raymarine Ray91 Modular Dual-Station VHF system has a 25-watt transmitter, dual-station capability, and a built-in AIS Class B receiver. Its black-box design places the transceiver out of sight; the included wired handset and passive speaker provide radio control.
The Ray91 AIS receiver can share information about nearby AIS-equipped vessels, including vessel name, course, speed, and CPA, with compatible MFDs over NMEA2000 or NMEA0183. Channel scanning, dual-watch, and tri-watch are listed features.
The Ritchie B-81-WM Voyager Bracket Mount Compass has Wheelmark certification for lifeboat and rescue boat use. Its features include a 3-inch CombiDamp dial, 12V green LED lighting, and built-in compensators to adjust for deviation.
The Raymarine ST2000 Plus Tiller Pilot is listed for tiller-steered sailing vessels up to 10,000 pounds. It includes a 12V socket, tiller pins, and mounting sockets.
Sailboat Rigging Hardware: Blocks, Shackles, and Deck Fittings
Blocks, shackles, and deck fittings are among the hardware categories sailors may consider when outfitting a vessel. Learn where to buy marine rigging hardware from top retailers.
