The Radial Head Spinnaker is a good all round general purpose spinnaker suitable for both cruising and racing. The panels radiate from the head to stabilise the shoulders and the horizontal panels ensure that the sail will fall within the average yachtsman's budget. The Tri Radial Spinnaker is a high performance sail manufactured with the panels of material radiating from each corner. The construction allows for greater stability and uniform shape which enables the sail to set closer to the wind. As with any spinnaker, a Jeckells Yo-Yo is a must.
