In hiking conditions, allow only one person at a time off the rail. There are very few reasons to get off the rail when sailing upwind. You can attach the guy to the pole by passing the pole back along the rail, loading it, then pushing it back into position. If spinnaker gear is fouled to leeward, clear it on the next tack. Pick your lightest crew member to leave the rail if necessary.
Most bad tacks are the result of poor steering.
Start the tack with a slow turn and once through the wind slow down again to allow the genoa tailor to trim the sail in. The box man should pull hard on the genoa sheet. If it fouls on the pulley it is faster to pull the pin to release the car. There will be enough time on the following tack to clear the problem and to reload the car. As the boat heads up into the wind, everyone on board should quickly move his or her weight to the old weather side, staying there until the boom crosses the centreline, then, slowly bring the boat back to it's optimal upwind trim.
