Anyone who has sailed a dinghy with a spinnaker chute will know how much quicker and easier it is than a boat without one. The problem is that the spinnaker on the Yeoman/Kinsman is very large and my fear was the spinnaker was too big to go down a chute. But by fitting the recovery line one meter up from the base of the sail it is pulled through the chute over its full length that means the system has very little friction within it. To recover the spinnaker the crew pulls in the sail through the chute with a recovery line.

By fitting the recovery line near the base of the sail when the line is pulled the spinnaker will enter the chute almost immediately that minimise the risk of sail touching the water. This is unlike the more conventional system you will see on a dinghy where the recovery patch is fitted in the centre of the sail and when the recovery line is pulled more than half of the sail will pile up on the bow and go in the water before it will start to enter the chute. Because this spinnaker handling system is easier it makes sailing with an inexperienced crew safer and racing less of a disadvantage. One of the most difficult manoeuvres with a spinnaker is a windward hoist because you have to launch the sail before fitting the spinnaker pole in place. With the chute system the pole can be fitted in place first therefore once the sail has been launched you will be in a position to take control of it immediately. The chute is also designed to be self-draining so any rainwater that enters the chute is drained away through two drain ports.

How it is fitted and why

The standard fitted forestay and jib anchor tangs have a habit of braking or pulling out. These are replaced with a bar bridge which is bolted in for the furling Genoa and the forestay is also relocated a safe distance away from the furling system. By using the purpose made spacer bar at the head of the Genoa and relocating the forestay it enables the furling system to be operated without fear of entangling the forestay. The chute is offset to port side. This helps accessibility on and off the bow past the chute. The internal moulding shown in the picture below is for a boat that does not have a bulkhead. For those boats that do there is a purpose made GRP tube that fits the back edge of the bulkhead. When bolted in place it prevents any water that may be in the boat getting in to the front compartment.

Rigging Requirements

It is important to keep the spinnaker halyard well away from the Genoa. Without this modification when the Genoa furling is operated the spinnaker halyard becomes entangled in the Genoa and furling mechanism. To reduce this risk it is important that the Genoa winds up in a clockwise direction. There is also a purpose made spacer bar fitted between the Genoa halyard and the forestay to further reduce the risk of any entanglement. Other alterations are the spinnaker halyard may have to be extended and the spinnaker sheets also may require extending if your sheeting system is a continuous line it is very important that it is not too short.
