Claes Marinuszoon Juynbol

Claes Marinuszoon Juynbol commanded the Rotterdam ship Neptunus in the attack on the Spanish Silverfleet. He was killed in the fight. His ship was one we know a good bit about, since it belonged to the Admiralty of Rotterdam:

• Neptunus (Neptunis in old documents)
• 26 guns: 2-24pdr, 16-18pdr, 2-12pdr, and 6-6pdr
• Crew: 85 sailors
• Built: 1623
• Size: 170 lasts
