Dutch Captain: Anthonis van der Haept

Anthonis (or Anthony) van der Haept served the Admiralty of Amsterdam. In April 1627, in 1628 and 1629, he commanded the large ship Thetis, a vessel of 250 lasts. Example dimensions for a ship of 250 lasts would be 128ft x 31.5ft x 13.5ft, although I expect that the Thetis had different proportions than these. The Thetis had a crew of 100 to 106 men and carried 34 guns, if you count steenstukken. The guns consisted of 2-24pdr, 2-18pdr, 2-chambered 18pdr, 12-12pdr, 10-8pdr, and 6-steenstukken. Carl Stapel credits the Thetis with 36 guns, including steenstukken, apparently. In August 1635, Anthonis van der Haept was part of two squadrons of ships under the command of Willem Codde van der Burch and Vice-Admiral Quast when they were operating against the Dunkirker admiral Colaert and his fleet, and fought an action against Coleart. Sadly, that is the extent of information that I have from my sources:
