Another alternative to handling spinnakers is to get a spinnaker launching bag. This one attaches to the bow pulpit and has a rigid ring to hold it open for launching and stowing the spinnaker. They are constructed from rugged nylon to make them last for years. They come in various sizes and colors.

Up to 300 Sq Ft Spinnaker - Small
