Just like our Aluminum Sprit - but in Plastic! The lightest possible physical mounting Sprit at just 0.5 Oz (19 Grams) this Sprit slides on your headstay tang, and stays there! No more tape and weird wire thingy’s that look ridiculous. Step up to an elegant solution! Vertical to avoid impacts, and rounded at the top to prevent damage to your spinnaker if you shrimp it - and cheap enough to be replaced if you do come into the pier a little hot! UV Resistant plastic.
