Windsurfers - do you have a sail number? If so then please email Paul Vlietstra <paul@veemail.co.nz> of Windsurf NZ to let him know. WNZ are updating the national sail number database and to keep your particular number you need to  let them know that you have a number and want to keep it, as well as being a financial member of an affiliated club (like the CWA).
