The Rolex Fastnet Race is one of the most tactically demanding of the world’s classic offshore races. Navigator Hugh Agnew breaks down the race strategy

One of the world’s classic offshore races, the Rolex Fastnet Race is also one of the most tactically demanding. Multiple tidal gates and the notorious British weather are just two of the major factors that can play a big part in your final result. Getting your race strategy right means doing your homework.

Expert navigator Hugh Agnew has lost count of the number of Fastnet Races he has completed, but takes a guess at 12. Of all these experiences, helping Leopard to a new course record in 2007 is his favourite. This is his advice for the course, from the start in the Solent:

Channel strategy

It is unforgivable not to have pre-planned this stage. By considering the expected weather and tide conditions for the next 24 hours, you will be able to decide whether you will reach Portland Bill with the tide or after it has turned against you.

Portland Bill

The first major tide gate and critical one. It’s crucial to plan early for this. If there’s any chance you won’t make the tidal gate easily, aim to pass well offshore. Tidal chart atlas NP257 is a must. If the tide’s with you, you will be squirted westwards if you pass close, but if you miss the tide, your tacking angle will suffer dramatically by staying in the strong tide. The true wind speed and direction will also change. Don’t believe the stories about the inside passage; it rarely works, if ever.

Lyme Bay

With east-going tide, stay north of rhumb line. As the sea breeze decays, you are in good shape to benefit from a land breeze, but if you want to hug the coast remember it’s a long way round.

Start Point

Tdal gate 2. Although it’s important to pick your spot depending on whether the tide is with or against you, the tides are generally weaker here. Having said that, don’t pass close if the tide’s against. You don’t have to go too far offshore to avoid the race.

Difficult to plan for this one until you get closer therefore judge as you approach. Again, tide can be a major issue. But it’s a high risk strategy to try to get in among the rocks to get out of the tide. If the tide is against you it’s better to stay well offshore.

Mounts Bay

Follow rhumb line to Runnel Stone, there’s usually little reason to hug the shore. Beware of the high Cornish cliffs which can influence the breeze and provide wind holes and traps.

Celtic Sea

Not too many options, but generally stay to the south of the rhumb line as any new weather is most likely to come from here and you’ll benefit first.

Fastnet Rock

Often tide against you here as you head for Pantaenius mark. Try to anticipate this.

Fastnet Rock – Report position to RORC (‘Ocean Six’ VHF72)

Pantaenius 51º 17.02’N 09º 41.04’W. This is a steel special mark yellow buoy with X top mark and radar reflector light Fl. Y. 3 secs.

Return leg

Traditionally a broad reach. Again keep south of rhumb line, especially as you nearly always get headed on the approach to Bishop Rock. Don’t get caught to the north and pinned to the Isles of Scilly. A great way to lose places fast!

The finish

Notorious place to mess up a good race! Penlee Point and Rame Head are classic windless holes. If in any doubt about the reliability of the breeze, approach from the south. Use binoculars and if possible log onto competitor trackers to see what’s happening ahead. In addition, use local weather stations and METARS to establish wind conditions. This may be a time to have someone up the rig.
