Similarly, there may be a special interest group (SIG) that you'd like to join. Click on "Usergroups", identify the group, and send a request for membership.
Your "Boat Registration Number" is important if you wish to join a NCA usergroup. Edit your profile and enter the correct details, if necessary, before requesting usergroup membership. The NCA moderator will check the hull number you give before approving your membership of his NCA usergroup. For most of the NCAs, this is what is required in this field:
- If your boat has a current valid certificate, then enter the full hull registration number (including country code), for example, "GBR 2131". Please leave a space between the country letters and the registration digits.
- If your boat has a hull number but your certificate is not valid or has been lost, insert the country code only and omit the digits. For example, enter "GBR" alone. Your certificate might not be valid, for example, if the boat has changed ownership but you have not (yet! ) informed the certification authority. It might be invalid if you have altered the boat in a way that requires fundamental measurement but you have not (yet! ) had it re-measured.
- If your boat does not have a hull number, or if the boat has never been fundamentally measured, please leave the field blank. You will not usually be eligible to join a NCA usergroup. You can participate fully in all the IOM general forums as an IOM owner, but the IOMICA Constitution says that only owners of registered boats can vote on IOM matters in their NCA.
