A few of the local put-ins have added EZ Docks (or similar). These are really great, especially for giving access to those who have physical limitations.
When I have used this dock/roller system in the past with my poly boat, I have definitely felt flex but it didn’t worry me because it was poly that flexes without damage. What do you think about using these long-term with carbon fiber sea kayaks? There are two single center rollers, one just below the water line and another right above the water line (see pictures). I have used this dock once with my Necky Looksha IV carbon fiber and felt a little bit of flex under the seat as it rolled over the center rollers. There is a point during pull out, similar to the picture below, where all the out-of-water stress is being placed on the two roller locations.
Since I did feel some flexing, I am just wondering if there is going to be long-term damage to the hull if I continue to use this dock system (FWIW, I am 180-ish lbs but might loan my kayak to others over 200 lbs).
Thanks for any advice and insights.
