Broker Comments

This 420 Sundancer has benefitted from thoughtful upgrades and consistent professional care. The interior is a standout — exceptionally clean, fresh, and shows far better than most boats of her vintage. Combined with her well-maintained Cummins diesels, refreshed cockpit, and glossy Awlgrip hull paint, she is one of the best-kept 420 Sundancers currently available.
