Bridge

What is the bridge on a yacht?

On a superyacht, the bridge is the room or deck level from which the captain and watch officers command the vessel. It contains the helm, throttle and bow-thruster controls, the chart table, the radar and AIS displays, the autopilot, the ECDIS or chartplotter, and the primary VHF and satellite communications. On yachts above roughly 24 metres the bridge is invariably a dedicated space, and on yachts above 50 metres it is usually built around an integrated bridge system (IBS).

"Bridge" and "wheelhouse" are often used interchangeably, but the distinction is useful. The wheelhouse is the enclosed structure containing the helm; the bridge is the broader command area, which may include open bridge wings on either side for berthing and pilotage. Layouts fall into three families: a fully enclosed wheelhouse (standard on long-range and explorer yachts), an open flybridge helm on the upper deck (common on sub-40m flybridge motor yachts), and the modern glass bridge - a wraparound array of large multifunction displays.

The bridge sits on the bridge deck, the deck level named for it, and adjoins the captain's cabin, radio room and, on larger yachts, a dedicated chart room.

Why it matters for yacht owners

The bridge is where compliance, safety and resale value converge. SOLAS Chapter V Regulation 22 sets binding visibility rules for any vessel of 55 metres and over built since 1 July 1998: an unobstructed horizontal field of view of at least 225 degrees, no forward blind sectors greater than 10 degrees, and window geometry that gives the officer of the watch a clear forward horizon.

Beyond compliance, the bridge install is one of the most expensive single systems on the yacht. A well-specified IBS from a tier-one supplier ages slowly; a fragmented bridge of mismatched MFDs is a flagged item at survey. The quality of the bridge directly affects insurability, charter classification and the captain's ability to recruit experienced watch officers.

Key facts

• The bridge is the command centre from which the yacht is navigated, manoeuvred and monitored.
• Core equipment: helm, ECDIS or chartplotter, radar, AIS, autopilot, depth sounder, VHF and satellite comms.
• SOLAS Chapter V Regulation 22 applies to yachts of 55m and over built on or after 1 July 1998.
• SOLAS V/22 requires at least 225 degrees of horizontal visibility from the conning position.
• "Wheelhouse" denotes the enclosed helm structure; "bridge" denotes the wider command area.
• An integrated bridge system (IBS) consolidates navigation, monitoring and alarm data into a single interface; standard on 50m+ yachts.
• Flybridge motor yachts typically carry a duplicate upper-deck helm in addition to the enclosed bridge.
• The "glass bridge" is the current generation of bridge install - wraparound large-format MFDs replacing dedicated analogue instruments.
