I own an Uno Max and have been testing out a mates Fenn Elite SL for the past few weeks....
First of all I better state Im not the ideal weight to be paddling the Uno Max as its made for the bigger guys and Im built like an anorexic racing sardine at 6 foot 4 and 74kg....
Love the bucket in the Uno, havent found anything else as comfortable. The Fenn is still comfortable, but not as nice....
I find the hatch in the think jsut great for shoving a jacket, spare drink bottle, or drybag with change of clothes in... Miss not having the hatch or even the bungies on the back deck with the Fenn....
I've got the slightly older model Uno Max with the enamel paint job and have to agree with another thread on the forum where they talk about how easily it scratches and marks, but the new Uno Max have gone for gelcoat finish to improve this Im pretty sure....
The chined hull on the think takes a bit of getting used to, especially in big water... Theres definetly a distinct jump from primary to secondary stability, but once there I find theres heaps of secondary to really dig that edge in and it flies across waves faster and tracks straight across waves than anything else I've paddled when you start doing this.
Its great downwind, but I would ahve to say the gunwales seem lower than the Fenn and you seem to get more water splashing into the bucket in the Think, but ti drains quickly... The lower sides definetly make the think easier to remount though....
But on flat water the SL was definetly faster than the Uno Max, and in moderate seas, especially the longer flatter ones I found the SL picked up the little lumps and bumps with a lot less effort than the think.... In bigger stuff the SL didnt feel as stable to me, but that could jsut be how much time I've spent in the Uno compared to only a couple weeks paddling the SL....
I've paddled a standard elite a fiar amount too and definetly feel that the SL is somewhat tippier, and found that I couldnt get the power down as easily in bigger stuff as at that moment when you need to put big power in to get down onto the wave at the top it wanted to wobble underneath me...
Fenn SL in vaccum glass was welcome change from the std elite glass boat of ~17kg I had paddled previously, and finish is nice and clean in white as always with the Fenns...
Dont like the fin shaped rudder of the Fenn though and find the Uno a lot easier and more responsive to turning... And its great being able to get hold of many different types of rudders for the think...
Anyways, hope that helps
