HMS Assurance was a notable 32-gun fourth-rate ship of the English Navy, constructed at Deptford Dockyard under the supervision of Master Shipwright Peter Pett I. Launched in 1646, the vessel measured approximately 106 feet 7 inches in length of gundeck, with a beam (breadth) initially around 26 feet 10 inches, which was later increased to approximately 29 feet 1 inch to improve stability. Her depth in hold was about 13 feet 6 inches, with a draught of roughly 13 feet 9 inches. Tonnage calculations placed her at around 34.08 tons, later increased to approximately 40.04 tons after modifications, and possibly up to 45.6 tons following further re-girdling. Initially armed with 32 guns, Assurance's armament varied over her career, including up to 42 guns in wartime. Her armament included culverins, demi-culverins, and sakers, with her gunports arranged along a full-length upper deck and additional guns on the quarterdeck. Her initial cost was £2,352, equivalent to about 336 tons at £7 per ton. Throughout her service, Assurance participated in numerous significant naval engagements. She served with the Parliamentary forces during the English Civil War and the subsequent Commonwealth Navy, taking part in key battles such as Dover, Portland, Gabbard, and Texel. She distinguished herself in combat with actions like capturing a Portuguese frigate in 1650 and fighting in the Battle of Lowestoft in 1665, the Four Days' Battle in 1666, and the Battle of Texel in 1673. She also engaged in operations in the West Indies and Mediterranean. In 1660, Assurance foundered during a storm at Woolwich but was subsequently salved. After the Restoration, she became part of the newly reformed Royal Navy, serving until she was reduced to a fifth-rate in 1690 and eventually sold in 1698. Her career spanned over five decades, marking her as a vessel of considerable maritime activity and historical significance during a transformative period in naval warfare.
