Hi Pheebobafat,
Flatwater spots are few in Port. You can kite in the river mouth about 500m up the river in a NE'er and it's pretty good, but ideally you need to launch from Pelican Island (across from the town green) so you need a boat or a kayak to get over there. It's best on a high tide as sandbars pop up when it's low right in the middle of the spot. Southerlies are apparently very gusty and not good so I don't know whether this spot will be any good in winter. It's my first season too, if your friend needs kite buddies he can PM me.
