I'm about to order some KajakSport hatches for my Njord build and can't decide on which front hatch to get. I'll use a 24cm (9") round one in the rear and could use either the same in the front or the smaller 20cm (8") one. Either will fit, I think, although the larger one might stick up a bit on the sides, even with a recess, due to the curved deck.

What are your opinions on the aesthetics of having equal-sized hatches both fore and aft verses smaller one up front? There is a fairly large storage area up front on the Njord so would the 8" hamper loading ability too much? Overall I'm tending towards the minimal on this build, so might be inclined towards the smaller one to reduce size and weight but still not sure. I'm not planning a day hatch or extra bulkhead in the rear but might put a small access hatch w/hanging bag up front for essential items.
