I have had my Voyager for about as long as anyone. I bought the first one sold (the second one built) and have paddled it a fair amount (as well as several other canoes) in the years since. I paddle it empty for day trips quite a bit, and find it handles a LOT better with a few gallons of water in a jug placed in the stern.
The real beauty of the voyager comes when paddling it loaded with gear though. Empty, it is a bit twitchy and my hips get a workout from the initial stability. The secondary stability is fantastic though. With a load in it, the Voyager settles in and is very comfortable and stable. It paddles just about as well, and doesn't get blown around any where near as bad as it does empty.
I don't really have any reservations about using it as a day paddler, but would choose my Advantage over it for that use. But when going for a trip the Voyager is an awesome solo craft. I paddle the Wisconsin River a couple times a year in it, often accompanying friends who are paddling my Sundowner 18. Granted, I am a stronger paddler than them, but I never have any trouble keeping up (in fact it's sometimes the other way around).
As a solo tripper, it's a 10. As an empty day paddler I would rate it an 8. The Voyager is very seaworthy and a lot of fun to play with in waves. I am very seriously considering a cover for it for windy days, but I don't like the idea of drilling it for snaps.
When I first looked at this boat, I knew it was going to be fast. 7.5 m.p.h according to my GPS. Dip the paddle in the water and instantly go 4.5 mph. Start to paddle, and it jumps to 5.5 mph. A nice cruising speed will bring 6.5, and an all out blast will hold 7.5 m.p.h. for 30 seconds. All this in a shallow lake, at 5,300 feet elevation!
Stability!!! Normally when I hop into a racing boat, there is a balance game. Not here! I was out in 2' powerboat waves, and the boat was incredibly stable. I never needed to brace.
Extreme speed and awesome stability, what more could one ask for in a cruising solo canoe. The boat is not legal for racing (it is too narrow), but for getting out on the water, it is bliss!
Disadvantages? This boat was not designed for whitewater or tight rivers. It was made to go forward, and to carry some gear while doing it. My test boat had the seat frame moved too far to the rear, so that the seat was all the way forward to be slightly bow heavy when still, but a nice trim when underway. We-no-nah also put in their new "wide butt" plastic seats, which are comfortable for sitting, but do not allow for kneeling. I prefer the smaller Kevlar seats, so I can change paddling positions if my back is bugging me.
I think the best comment about this boat, was the smile I had on my face when I was keeping up with a great paddler, and he was in an Olympic K-1!
