Looks like hull# TSP00354M81K or TSP00354M8IK -- I can't read the second to last digit (see photo)
Where do I register this thing with the J30 association?
I just added your boat to the database. Click on your forum profile now and you'll see a link to the class database where you may edit your record. This is hull 354 which was missing from the database. M81K is the date code
