Grashaven (Stichting Jachthaven Hoorn)

Grashaven is a large, spacious harbour with mooring buoys, giving it a relaxed, open feel rather than the packed-in vibe of smaller marinas. Good facilities on site, and Hoorn's beautifully preserved old town — one of the best in the Netherlands — is just a 10-minute walk away. It's the kind of stop where you end up staying longer than planned.
