I'm the owner of a young hostel designed for kayakers in Pucon, Pucon Kayak Hostel. If you still need boats then I'm proud to announce that we have one of the best rental fleets in Chile.
Here is a link to the Pucon Kayak Hostel rental fleet.
Regarding the Siete Tazas: I'm near there in the surf town of Pichilemu at this moment. We too decided to drop the Teacups due to low water. You'd either be seal launching into green water or swimming pools.
Pucon is still holding out well as is typical. Next week we're planning Upper and Lower Palguin, Upper and Lower Trancura, play sessions at two local waves, San Pedro, Llancahue, and Upper/Middle/and Lower Fuy. So, there's still lots to tackle.
If you need on the ground help with logistics then I'd be happy to help you enjoy your adventure.
