van Maanen states that the British captured or burnt Delfin in 1779,[1] i.e., before her completion date. The year 1779 appears to be a typographical error for 1799.
HMS Dolphin was the Dutch 7th Charter Dolfijn, launched in 1780 at Amsterdam.[1] In 1781 she was under the command of Captain Mulder when she participated in the battle of Dogger Bank.[4]
HMS Wolverine and HMS Arrow captured her on 15 September 1799 off Vlie Island. The Royal Navy took her into service and commissioned her in November as the sixth-rate HMS Dolphin under the command of Lieutenant R. M'Dougall.[2] She became a transport in 1800, and a storeship in 1802. She was broken up in 1803.[3]

^All linear measurements are in Amsterdam feet (voet) of 11 Amsterdam inches (duim) (see Dutch units of measurement). The Amsterdam foot is about 8% shorter than an English foot. The basis of measurement is also different.
