While Willem Molengraaff and I had been testing quite a lot of seakayaks during the last 15 or 20 years, we only noticed that there are not very much testreports on seakayaks available on the internet.

Of course we know the reports in The Seakayaker Magazine. They seem to work with a standard group of testers and they make a structured summary of the remarks they recieve from the testers on the kayak.
But besides that we did not find any structured tests of seakayaks in the world.

Of course there is paddling.net where everybody can posts his or hers comments on a kajak in the review-section. This is of course very interesting, but you not always get a complete impression of the kayak.

Than there is the Norwegian magazine "Paddling" where, since 1 or 2 years, testreports are now published. The point is: you must be able to read Norwegian and these tests are not available in the "world wide web".
As I can read norsk I am thinking of subscribe to this magazine. Only have to investigate how to pay without to much administrative costs for crossing the money over the Dutch border.

But now something has changed as I noticed that there is Douglas Wilcox testing seakayaks as well and publishing reports on his weblog
SeaKayakPhoto.com.

I am happy to mention 3 tests from this collegue in testing:
Rockpool - Alaw and Alaw Bach
P&H -Quest LV
Valley - Nordkapp LV
