NOT to be redundant, but I documented my Catalina
34 and used West Marine
3" letters glued in the bilge
(then covered with epoxy) where they are easily seen by just lifting the Bilge
board. On some boats the No. is drilled into a permanent member
Once that is done, the state will still require you to register the boat with the state so they can get the revenue (tax) annually. They then give you a state decal that needs to be displayed on the external hull
or where it is clearly visible by a tax man and police. If you move the boat to another state, you have to register it there within so many days (usually 60 days or less) If you are transiting/cruising through another state, don't sit at anchor
or in a marina long or the authorities will tell you to register there also. "Everyone/State wants a piece of the action!
Enjoy the boat!
