HNLMS Wamandai (A870) was a tugboat of the Royal Netherlands Navy (RNN).

[1] On 27 August 1958 Wamandai was laid down and on 28 May 1960 she was launched at the Rijkswerf in Den Helder.

[2] Wamandai was originally meant to serve in Dutch New Guinea.

[7] As a result of increased tension between British Guiana and Suriname the Wamandai was sent in 1964 to guard the entrance to the Corantijn River.

[8][9] The Wamandai was used in this role until the hydrographic survey vessel HNLMS Luymes arrived in Suriname, after which the Wamandai returned to the Netherlands Antilles.
