Boat registration requirement question

[sled]

  I am thinking about taking my 12' aluminum boat with a 6 horse to kayak point crabbing.
  From what I have read I understand it needs to be licensed.  I have had others tell me it doesn't because of the size of the boat, and the motor.
  Am I misreading the law?

Needs to be registered

It needs to be licensed if you use it in federal navigable waters such as Lake WA, Puget Sound,  Columbia river, etc.

Yes:

To navigate, operate, employ, or moor your vessel in Washington, you must have a Washington title, registration card, and registration decals, except:

If your vessel is a canoe, kayak, or a vessel not propelled by a motor or sail.
If your vessel is less than 16 feet in length and has a motor of 10 horsepower or less and is used on non-federal waters only.
If your vessel is properly registered by a resident of another state or country who uses Washington waters for 60 days or fewer.

That's what I thought. 

Thanks guys.

When you go to register it bring some proof that you have paid the sales tax on the boat and motor or something that shows that it was a gift.  Otherwise you are likely to be sent to pay “use tax” before they will process your registration.
