Just upstream of the bridge at Dordrecht. Nearly lost my mast there with the current flowing, engine stopped and approaching the slowly opening bridge...... Luckily the engine started first turn. Also misread the opening times as only twice a day and did not read it was different on each day and we arrived on a Tuesday after reading the saturday opening times.
Sint Maartensgat, Dordrecht.
You used to have to press a bell on the waiting pile and the havenmeester came and hand cranked the bridge to let you in. Someone told us that it was a nice quiet yacht club, so it was apart from the bongs from the church! One night it went wrong and chimed 23 o'clock.
