floor to side joint in master angler

[lunasea17]

Hoping I can get through the season as is. In the fall I will use an epoxy cabosil type putty and possibly a wrap of several layers of glass-resin wrapped from about 6" up the side{under the carpet} over ledge below it to the gutter. That is if I don't have to rip up some of the deck. I'm tempted to caulk it for now but am afraid that that would be a pia to remove when I try to fix it permanently.
