Play to Sail: The Wind Shifts, A Lift Or A Header Will Affect Your Boat

Yes, it does: the wind shifts. This is important when sailing racing because it creates an opportunity to gain distance on the opponent's RC boats or it will influence your losses.
Wind shifts are a main strategic and tactical factor.

How best to manage to sail the wind shifts steering your radio sailboat

Sailors say that an RC boat can be "headed" or "lifted" because a wind shift can interfere in different ways in the direction the boat is sailing.

ㆍThe lift

If your RC boat is sailing upwind, the wind is lifting when its direction changes shifting from the bow toward the stern.
This usually is a good shift, because your RC boat will head more upwind: it will allow you to head up a few degrees with the lift and to keep a direction close to the weather mark while racing.
If you don't need to luff and go higher to point your destination upwind, when your RC boat encounters a lift, just trim the sails: release a bit them to gain speed while maintaining the direction.
When your RC boat is running downwind, the wind lifts when it changes direction by turning towards the stern.
It is usually a negative shift. If you're maintaining your run dead downwind, a wind lifting will force your sails to gybe, or you will have to head up away from your route to stay on the previous tack.
If your point of sail is a reach, if the wind changes direction lifting, you will have to ease the sails - this means also that your RC boat will sail slower downwind.

ㆍThe header

If your RC boat is heading upwind, the header occurs when the direction of the wind shifts towards the bow.
Encountering a header, the sails of your RC boat will start to luff. You will have to accommodate for the new wind direction by steering: you need to bear away a few degrees your route, so, this means that a header will force you away from your destination straight upwind.
Since a header is a shift that heads your RC boat more downwind, you need to tack your sailboat in headers to sail straight up the course toward the windward mark. If a boat is sailing on a heading tack, by tacking it will sail in a lift on the opposite tack.
When your sailboat is running towards a point straight downwind and the wind shifts towards the bow, you will be able to sail at an angle that will point your RC boat closer to your destination. At the very least, a header will allow the dead downwind sailor to be sailing on a deep broad reach. If, during a reach, your bow is pointing towards the mark, trimming in the sails is all that's needed with a header.


When radio sailing, you can't rely on the compass or landmarks to determine a wind shift. So, to detect if the direction of the wind is changing, you will relate your position to the other sailboats.
If the direction of the wind is steady, both port and starboard tacks are exactly equal. When a wind shift occurs, one tack becomes more favorable: a header on one tack is automatically a lift on the other.

Look at the opponent's boats: how much they are lifted or headed?

In case of differences, consider that one tack becomes more favorable than the other. If you're sailing upwind, an RC boat lifted sail more closely in the direction of the weather mark than the other boats do.
If the opposite tack your RC boat is sailing on becomes more favorable, you should consider tacking.
Try to sail on this more favorable tack as the wind shifts back in a header, then the opposite tack becomes the more favorable route.
Your goal upwind is to sail each tack when it is lifted. By sailing the lifted tack, your RC boat will sail a more direct route to the weather mark.

Remember to have a long and a short perspective view of the wind conditions.

Stay focused on sailing well in the wind you have (immediate effects) and manage it at your best - i.e. when your RC boat encounters a gust - but try to anticipate the wind changes (short terms effects) - like puff or lull - and be prepared to react to them, by proper steering and trimming the sails.
Always consider how is better to position your RC boat: due to the direction of the wind or its changes or for a better wind pressure in relation to the opponent boats and the next mark. Joysway is a professional toy and hobby model designer and manufacturer of RC Sailboat model.
