Totally different world.

1) You are in a fresh, not a salt water area.

(There is a reason they refer to fresh water as "sweet water")

2) Since you are at a higher latitude, you have a much shorter season,
say 4 months, maybe 4-1/2, thus much less UV to content with than in the
San Diego area with year around UV damage.

As an example, given the same amount of time on the water, if you get 10
years out of a set of sails on the Great Lakes, but you might only get
2-3 in San Diego.

Same applies to coatings.
