Settle the purchase
, de-register with USCG as a first step. Well, actually if staying at a marina for any time after purchase then Insurance
will be the first step.....
You'll need that USCG paperwork and Bill of Sale
info to register in Canada.
When Canadian rego completed, leave California under Canadian flag. Pity its in San Fran - not simple to go to a port in Oregon
. But you need to stay out of California for a minimum time, think it could be 15 days. Then re-enter California under Canadian flag with a cruising permit
for the length of time you wish/need.
Someone said if you did not stay in California more than 89 days after purchase you will not be liable for state tax. For Washington
its 45 days, even to a foreign national if a WA registered broker is involved. Broker gave me the relevant statute. Also, in Washington
you can purchase a one year cruising permit
for $500 at the time of vessel purchase and can also get up to three two month cruising permits for $25 each but requiring an over night stay out of country (in Canada or Mexico) each renewal. I'm not sure if the one year permit is an alternative to leaving within 45 days or not. But at least Canada isn't far away from Seattle
so I'll just leave within time limit, to be safe.
So, just get out of California before the relevant time limit and State taxes will not be applicable. Canadian taxes will be applicable on first entry to Canada. But if no first entry, then you wont pay those either, as Pete says.
