Give Dad a Father’s Day to remember with a private narrowboat day hire from Cow Roast Marina on the Grand Union Canal. Father’s Day 2026 is Sunday, 21 June. We currently have just one boat available. If you’d like to celebrate Dad with a private canal day, we recommend booking early to secure your final slot. Father’s Day is the perfect excuse to give Dad something a little different this year. Not another pair of socks. Not another mug. Not another last-minute box of chocola
