You will probably be using this boat in many of the same waters where I
cruise each summer; Gulf Islands, Desolation Sound, Princess Louisa,
Etc.

There is nothing abut the basic design on the boat you are mentioning
that would disqualify it from most peoples' consideration for that
purpose. However; you will be far happier with that boat remaining in
the inland waters listed above than trying to tackle the west side of
Vancouver Island. You'll want to stay off the Strait of Georgia (as do
nearly all the rest of us)
when it gets snotty.

Your challenge is going to be trying to find a Carver of that vintage
in good condition. There was a lot of wood used in the construction of
the boat, and unless it has been kept under covered moorage for most of
its life it's unlikely that the average specimen 33 Mariner won't
require extensive repairs. You will almost certainly need to settle for
gasoline engines, and the costs associated with overhauling or
replacing a couple of engines would equal the budget you're working
with for the entire project.

So good luck and shop carefully. If you find a 33 Mariner in good shape
it should be suitable
for fair weather use in your area. If.
