It is important to keep to the marked channel because of the training walls which extend some way out from the entrance. There can be a current of up to 1.5 knots in or out of the river as well as a cross current where the training wall rises above sea level.
Yachts can anchor past the pier, close to the Royal Brunei Yacht Club (RBYC) which is a little way up the river on the starboard side at approx 5°0.1'N 115°04.0'E. The RBYC anchorage is good holding in mostly mud. Don't come closer in than the moored yachts as it gets shallow fast.
There are no longer any free moorings here and the locals will get upset if you grab their mooring while they are out sailing for the day.
A recommended anchorage on the way to Brunei from Kuchin, is an unfinished marina area in Jerudong, about 20NM before Muara. There is a small island inside the breaker. Anchor in four to five metres with good holding but be careful at the entrance. Be careful at the entrance. There are four massive steel pillars in front of the entrance which are unlit at night and four more inside the breaker area. Anchoring is permitted but you are not allowed to go ashore.
