This is probably a long shot but as my name suggests I live on Virgin Gorda and just purchased a Hobie Getaway. It is, however, missing the top half of its mast (also known as the comptip). Before ordering one and shipping it down from the States (which is a pretty expensive endeavor) I wanted to check around the islands and see if I couldn't located one.
Let me know if anyone has a lead! I attached a photo of the part.
