Apparently, you now need to get a title for any 16' or larger kayak or canoe even if you don't have a motor for it. Started 1/12/2010 and applies to even older kayaks you got years ago.
NO registration is needed (No decal, no 3" numbers, no annual fee) just a

title.
No way to tell on the water which kayak is titled or not as you are not required to carry the title. So Marine Patrol don't care.
When I asked the tax clerk/supervisor "why bother" with such nonsense she replied "So the state can collect more money"
Apparently they will "create" you a title if you lack paperwork (all you need is make, model & VIN #)
What this does is when you sell your 16' kayak for say $1,000 some poor sucker is going to have to pony up the 6% sales tax in addition the the title fees.
Nutz!
