2.5 miles from Chatham island, Port Blair
Anchor in 6-8 metres just south of the jetty ashore, having first asked permission from Port Control. Ross Island used to be the administrative certre of the Andamans under British Colonial rule. It has a quite, park-like atmosphere with crumbling brick buildings overgrown with strangler figs, spotted deer, a variety of ornamental dustbins and a local coconut seller.
This is a very useful anchorage if you want to return to Port Blair without re-entering the harbour (and all the associated paperwork to get back out again). From the anchorage take your dinghy across to Aberdeen Jetty. There is a small boat marina there with a tidal sill, so arrive at mid-tide or above. Aberdeen Jetty is in the middle of Port Blair town.
