I assume that Willem Ham's ship Sampson, a Noorderkwartier landsschip, was a 116ft ship. I could be wrong, but it seems likely. The Sampson was captured by the English on 22 July 1652, and was a sufficiently good ship that the English placed the Sampson in service in their navy under the same name and also carrying 26 guns. The Sampson served under the English flag until being sunk by gunfire at the Three Days Battle. The Sampson was the only English ship lost in the fight, being sunk on the first day.
I am less sure about Jan Warnaertsz Capelman's ship, the Alkmaar. The Alkmaar also was armed with 26 guns and was captured by the English in the Channel in Jun 1652. The Alkmaar was one of the 36 ships activated for service in late summer of 1651. This group of ships was intended for service in the Mediterranean against the North African pirates as well as increasing the Dutch readiness for a possible war with the English. The Alkmaar may have well been a 120ft ship, but could have also been a 116ft. All Noorderkwartier landschepen seem to have been either 116ft or 120ft long. The only exception was the 130ft Eendracht, armed with 40 or 41 guns which served in the Mediterranean Sea until after the Battle of Livorno in 1653.
