How about raising the mast? |
The mast can be hauled into position by a single person using the purchase of the main sheet blocks provided that lateral movement is prevented by the use of temporary short shrouds attached to the rings that hold the floats on (see below). But even this is unecessary unless you have strong winds. I now lift the mast up in one movement on my own. I have the spinnaker halyard already attached to the bow and once the shrouds are tight I pull on the mast-foot-end of the halyard until it is tight. Then the mast is secure and I can attach the forestay via the jib furler at my leisure. |

During mast erection or lowering a couple of short temporary shrouds will help stabilise the mast in windy conditions or when you are doing the job alone. |

Note the use of the main sheet attached to the ring at the bow intended for the gennaker. This gives plenty of mechanical advantage and makes the job of raising or lowering the mast really easy. |
