The 30-second answer
- Want wireless wind (no mast cable)? → WS320 + WS320 Wireless Interface.
- Want wired wind (no battery)? → WS310 + WS310 Wired Interface + a WS300-series mast cable.
- Replacing an older 508 / IS20 sensor on a Triton²? → the 608 reuses your existing cable and bracket.
- Wind reads low or sticks? → service the masthead: new speed cups + speed bearing (+ vane if damaged).
B&G wind sensors — what each one needs
| Masthead sensor | Type | Interface required | Mast cable | Connects to |
|---|---|---|---|---|
| WS320 (wireless) | Wireless, solar-powered | WS320 Wireless Interface | None (wireless) | NMEA 2000 |
| WS310 (wired) | Wired | WS310 Wired Interface | 20 m / 35 m WS300-series | NMEA 2000 |
| 608 | Networked (legacy-compatible) | None — connects to Triton² / T41 directly | Reuses 508 / IS20 cable | Triton², Triton T41 |
| 213 (wired masthead) | Wired, pulse / analogue | Connects to the processor directly | Legacy mast cable | B&G H5000, H3000 |
Tip: WS310 and WS320 deliver the same wind-angle and wind-speed accuracy. Choose WS320 to avoid running a mast cable; choose WS310 if you prefer no battery at the masthead.
Shared masthead spares (service parts)
| Spare part | B&G part # | Fits |
|---|---|---|
| Wind speed cups | 000-15140-001 | All B&G masthead sensors — WS310, WS320, WS700, 608, 508, 213 |
| Wind vane assembly | 000-15144-001 | WS300-series & WS700 |

Short model guides
WS wind series — WS320 vs WS310 vs 608
WS320 (wireless) is the easiest wind upgrade: solar-powered masthead, no cable through the mast, wind output 5×/second, same accuracy as wired. Needs the WS320 wireless interface at the base and puts data on NMEA 2000. WS310 (wired) gives the same data with nothing to charge at the masthead — it needs the WS310 wired interface plus a WS300-series mast cable (20 m or 35 m). 608 is the networked sensor for existing Triton² / Triton T41 systems and reuses older 508 / IS20 mast cables and brackets, making it the simplest like-for-like replacement. All three share the same masthead service parts (cups, vane, bearing).
Triton²
B&G's core NMEA 2000 sailing-instrument system. The Triton² 4.1" color display shows wind, speed, depth and more; build a complete system by adding a wind sensor (WS310 or WS320), a DST810 speed/depth transducer and as many Triton² or Triton HV repeaters as you need. The simplest full-system route is one of B&G's Triton² system packs.
H5000
B&G's performance platform, built around an H5000 processor (CPU) that calculates true wind, targets, polars and laylines for racing and performance cruising. It accepts both analog and NMEA 2000 sensors and drives H5000 graphic/analog displays as well as Triton² and Nemesis screens. Choose H5000 when you want calibrated, race-grade performance data rather than basic instruments.
Nemesis
Nemesis 7, 9 and 12 are wide-format sailing displays that show instrument and navigation data on configurable, graphic pages. They connect through the Nemesis Hub and integrate with Triton² and H5000 systems and B&G WS wind sensors over NMEA 2000. Choose Nemesis for the richest on-deck display without a full MFD.
Frequently asked questions
Which B&G wind sensor do I need for a Triton²?
Either the wired WS310 (with the WS310 interface and a mast cable) or the wireless WS320 (with the WS320 wireless interface). Both report to the Triton² over NMEA 2000 with the same accuracy. If you already run an older 508/IS20 sensor, the 608 reuses your existing cable.
What's the difference between WS300, WS310 and WS320?
"WS300 series" refers to the masthead hardware family and its shared service parts. WS310 is the wired sensor; WS320 is the wireless, solar-powered sensor. They share the same speed cups, wind vane and speed bearing.
Does the WS320 need a mast cable?
No. The WS320 is wireless and solar-powered — it only needs its base-station wireless interface on your NMEA 2000 network. Only wired sensors (WS310) need a WS300-series mast cable.
My wind speed reads low or sticks in light air — what do I replace?
Usually the speed cups and the speed bearing, not the whole sensor. Replace the wind vane too if it's cracked or faded.
Which mast cable length do I need?
Measure your masthead height plus the run to where the wind interface mounts, then add slack. We stock 20 m (65 ft) and 35 m (115 ft) WS300-series cables.
Can I mix B&G displays?
Yes — Triton², Triton HV and Nemesis displays all share data over the same NMEA 2000 network, so you can combine them with any WS wind sensor and a DST810.
