The CPT is buildt like a tank, I've never had a problem yet with over
2K miles and in some big weather.


2000 miles since 1999??? That works out to aproximately 340 miles per
year...

.... Or about twice as many miles as you manage.

Let's imagine that you go sailing **every** day from May to September.
Your
photographs prove that you never go more than a mile from your marina.
That means that you do a maximum of 165 miles per year ... **if** you
manage
to go sailing every single day of your wimpy season.
