The region is labelled Rio de Janeiro and not one of the 22 boats is in the city. Fourteen are at Paraty and seven at Verolme near Angra dos Reis, with one more at Porto Imperial — all of them in the Costa Verde, the stretch of coast west of Rio where Ilha Grande and a scatter of smaller islands shelter a bay roughly sixty miles across.
That bay is the whole point, and it is unusually forgiving water. Ilha Grande breaks the Atlantic swell before it reaches you, so the inside stays flat; the islands are close enough together that you can move three times in a day without raising a sail; and the depths are generous almost everywhere. If you have sailed the Caribbean and found the passages tiring, this is the opposite experience.
The two bases give slightly different weeks. From Paraty at the western end you have the colonial town itself, the long inlet of Saco do Mamanguá immediately south-west, and Ilha Grande a half day east. From Angra dos Reis in the middle you are among the densest part of the island cluster from the first hour — Gipóia, Porcos, Cataguases — with Paraty as the far point instead of the base.
What you should know before booking is on the Brazil country page, because it is counter-intuitive: the best months here are not the southern summer. November to March is the rainy half, and April to September is drier and calmer, with the shoulders either side of that the best of the year. The wind is light — this coast sits below the trade wind belt — so budget fuel and pick legs you are happy to motor.
The fleet averages 13.2 metres with a 2022 build year, twelve monohulls to ten catamarans, and all 22 boats change over on a Saturday.
