So I heard back from the PPS people about the rental boats. I told them I have an NDK Pilgrim Ex and would like something similar. They are ONLY renting poly boats for the symposium, so my options are limited. They are recommending a Wilderness Systems Tempest 16'5". According to them, it's "a sleek poly skeg boat." https://www.wildernesssystems.com/us/kayaks/tempest-165 Having just gotten rid of a WS boat, I blanched a bit, but the link above says that it's for smaller paddlers and it DOES have a skeg. It is wider than my Pilgrim, but most boats are. Will that be OK for me, do you think? I'm 5'6" and 128 lbs. And I want to work a lot on rolling.
