IOS Round the Island Race is a long established, long distance event designed
to test the sailing skills and endurance over a 40-mile course. Sailed clockwise
around the island, starting and finishing at IOS Sailing Club, the race
includes tidal sea, river & estuary sailing.
The event is the longest dinghy and board race in Europe — it should not
be confused with so-called 24 hour races, which allow for a change of helm and
The race is open to all classes of dinghy, catamaran and sailboard but
any dinghy or catamaran that does not have an RYA Portsmouth Yardstick number should make contact with the IOS Sailing Club before the day of the event.
The race starts and finishes at Sheerness and is a clockwise circumnavigation
of the island. Firstly by sea to Leysdown and around the NE tip of the
Island, Shellness, and then into the Swale estuary. The Swale gradually
narrows into the river, with the lifting road bridge at Kingsferry acting
as an obstacle at its narrowest point. Larger dinghies and multihulls
have to be stopped, heeled over and walked under the inner span of the
bridge. The course continues up the Swale, through the ancient port of
Queenborough and into the mouth of the Medway, before finally rounding
Garrison Point to the open sea and the short distance back to the Club.

Typical passage times are 3 - 10 hours.
Every boat should be capable of completing the course in whatever conditions
are encountered. Particular note should be made of the possibility of
being reliant upon your own resources for a protracted period, even returning
after dark or in fog.
All boats buoyancy arrangements must be in thoroughly efficient working
order. Safety boats are instructed that, if necessary, crews are
to taken off, and boats left to be towed in later. It is therefore suggested
that all boats carry an anchor.
