According to the
Government web site, any vessel modified to accept a motor must be registered:
Boats/vessels that must be registered
If your boat has a motor, or is fitted for one, it must be registered with the Department and is subject to an annual registration fee. Yachts, canoes, surf skis and other craft without motors and not fitted to carry one, are not required to be registered.
That's a real pain. It doesn't distinguish between electric and petrol/diesel powered motors.
I've just gone through this process to get a
catamaran registered, so it's fresh in my mind.
First, you'll need to take the "boat" to a location to have a "boat code" fitted to the hull. In the catamaran, they drilled some holes in the hulls and riveted the plates to the hulls. Good luck with the pontoon on that one.
You'll need to take proof of ownership of the boat. I don't know what they'll do about assessing the size of the motor (in HP) or its serial number. It'll cost around $100.
After you've been given a boat code, you take the boat code papers and Application to Register a Boat into the Dept of Transport and pay about $100 to register it.
I'm guessing the guy fitting the boat code will laugh and struggle to comply with the regulations as written. You'll get some weird questions from the people at the counter of the Dept of Transport. It's going to be a battle ….
However, I have heard of the Marine Police fining kayakers $120 for having an unregistered motor vessel when they were running an electric motor (like I do). I've been running one for about 5 months now on my yak and haven't had any problems with the police yet, and they have gone past.
Given that the vessel
should be registered, if the law were obeyed fully, I would expect that you should have a recreational fishing license with you at all times in that boat. If you are caught fishing from a motor boat without the license, they
can confiscate all the gear you are using, including the car you used to get there. If they can ping you for not registering a vessel that should have been registered, they could easily ping you for fishing from that boat without a license. I carry a license for this reason: I can wear a $120 fine for an unregistered boat, but I'd be heartbroken to lose that boat, plus my fishing gear, plus my car just because I was not carrying a license when I landed with fish.
Cheers,
