I wrote a lengthly reply to Mike Daly then deleted it.
The Shadow and Eclipse are fine boats. I still preffer my NDK and
Capella but I paddled an Eclipse in a 20 knot breaze a month ago
without using the rudder and it was just fine.
The wind works on it more than it does on my boats but it is built for
a larger paddler.
If you want to check out my credentials just type Alex McGruer on any

You have a fine boat and there are brilliant people on this group. Not
all enjoy the same opinions, it would be boring if we did.
Have a good one
Alex
