The relationship between Radisson and Sportspal is a bit confusing, but spending some time searching the subject on the web can fill in a lot of gaps.
I don't know the entire history of the companies or their products, but I can tell you that the products have changed over the years, so anything said about an OLD Radisson may not be true of a new one.
If you are comparing an OLD Radisson canoe to a Sportspal (by Meyer), you will find quite a difference:
- The OLD Radisson is .022" thick while the Sportspal (by Meyer) is .032 thick.
The weight of the Sportspal is higher accordingly.
- The Sportspal (by Meyer) is constructed from two stretch-formed pieces of aluminum, joined along the centerline (at the keel).
The sides are smooth, fair, uninterrupted curves from front to back.
-The OLD Radisson was NOT stretch-formed to create smooth-flowing, fair curves along the sides. Instead, the sheet of aluminum was folded up and overlapped in a couple of places to create the hull sides. The overlapped seams are then slathered with some kind of sealant. This leaves a somewhat lumpy, unfair appearance to the hull, the sides being somewhat faceted at the vertical seams.
The big advantage of the (old) Radisson is its extremely light weight. The smaller ones were only around 30 pounds or so.
The big disadvantage is the lack of ruggedness because of the .022" hull thickness. When I was looking for one, almost every ad I saw showed a canoe that had some pretty serious wrinkled and crumpled areas from being stove-in at some point. Generally, they were claimed to be non-leaking, but they looked pretty bad. Even the better ones were a bit ugly just because of the "lumpy" vertical seams along their sides.
The advantages of the Sportspal are the improved ruggedness due to the thicker (.032") material, and the improved appearance due to the stretch-formed hull. The disadvantage is the rather considerable increase in weight (again, due to the thicker material). I ended up getting the biggest (15' I think?) Sportspal squareback, and while it is claimed to be "lightweight", it is in fact only a pound or two lighter than my 17' "regular" Royalex canoe.
As I understand it, these two companies have combined operations and are now offering identical products under either name. If that's not correct, hopefully someone "in the know" will straighten us out on the matter.
