After having been through this in Texas my recommendation is to fight. Contact your local representative and make it clear that if they do not vote against a law to register non-motorized boats you will:
-Vote against them at the next election
-Send money to their opponents at the next election
-Come to public meeting and ask embarrassing questions
And that you are also planning to distribute the names of the supporters of this law to the local catamaran community.
It's winter, get your friends to send emails. Make your local representative think this is really important.
Registering sounds simple but it is a real pain in the butt and is expensive.
Currently you are not part of the great and all powerful "System". Nobody cares about you and nobody thinks you are worth enough to bring into the "System". To register boats you must be brought into the "System". For example to make registering boats work, you must title them (how do you enforce a ticket written against an unregistered Sunfish skippered by someone wearing a lifejacket and a bathing suit with no ID). Titling and Registering boats is expensive, at least as much as registering a car. To pay for making the "System" work for boats, you must tax the boats (sticker taxes, Title Transfers, Sales Tax, etc)
Also you don't fit the "System". Many non-motorized boats have no ID numbers or their ID numbers do not match what the state expects on their form. Registering a Marstrom is a 2 day job in Texas.
If you need to explain why this law is stupid send some of these question to your local representative:
Since the stickers will not stick to Teflon paint, can I put them on before I paint the boat? (i.e I will put your sticker on but then I am going to paint over the cursed thing)
I don't have a hull number, can I register my sail number?
what if my hull numbers don't match?
which side of which hull do I put the stickers on?
do I put the stickers on the inside or the outside of my hulls?
I'm still not sure what you are saying, could you just give me 4 stickers to put on the inside and outside of each hull?
What if I buy 2 new hulls, sell one of my old ones to someone, and keep one as a spare? (be sure to get the answer to this in writing)
