A couple of additional points:
1. Dry Deck and another similar product called Deck-Mate seem almost identical, but have different manufacturers.
2. The two in #1 above and Kiwi Tile almost certainly have different interlocking patterns where they join, so will not be interchangeable, or mixable, in combinations.
3. I have Dry-Deck, like it, but it does
A. get squishy when really hot,
B. is uncomfortable on bare feet, if yours are tender.
To offset these issues, I use the Dri-Deck on top of indoor-outdoor carpeting, which makes it much softer to the feet. In hot weather, wetting the carpet cools the Dri-Deck, and keeps it firmer. Blue Dri-Deck over red indoor-outdoor carpeting also looks very nice.
The drawbacks, however, are
C. cleaning the combination requires a lot of high-pressure water to blow the small particles out of the matrix, and
D. the Dri-Deck stays put on the carpet, but the combination can move around a bit in the cockpit and requires some re-positioning occasionally. I think the movement is due to water underneath the carpet (between the carpet and the hull) that lubricates the carpet and helps it slide around.
E. some fishing/crabbing/shrimping with this combination would be OK, but if you have a lot of blood, fish guts, or other debris that can smell and/or get trapped in the fibers, the carpet would be an odor trap, and I wouldn't recommend this combination to you.
If I had it to do over again, I'd look for a large, single piece, anti-fatigue mat in some color other than black that would fill the whole cockpit and stay put.
