Portsmouth Anchorage
Portsmouth Anchorage sits in Prince Rupert Bay, one of the largest and most sheltered bays in the Eastern Caribbean, giving you plenty of room to swing and solid holding in calm, protected waters. The bay is fringed by the lush, mountainous landscape Dominica is famous for, and the town of Portsmouth is right there — a laid-back spot with local restaurants, markets, and easy access to the Indian River, one of the island's most iconic natural attractions. The vibe is unhurried and genuine, with local boat boys offering guided tours and fresh provisions straight to your anchorage.
