The SeaKayakPhoto site has beautiful photos of sea kayaking venues. One of the blog ‘Pages’ on the site, called Tests and Reviews, focuses on reviews of equipment for sea kayaks.
All of the reviews are based on actual use and include links to suppliers. Reviews cover a wide variety of equipment used in sea kayaking such as clothing, electronics, stoves, etc., etc…. much of which is applicable to cruising in any small boat, including oar cruisers.
Definitely worth a look.
