I paddled Dean Trexel's Outer Island recently (thanks Dean, beautiful kayak!) and am interested in getting some impressions from those of you who have paddled the Night Heron and Shearwater's Oyster Catcher, which appear to my untrained eye to all be rather similar. Also, for stitch and glue, how important is marine grade plywood as opposed to plain old lauan? It seems like many of you have used the cheap stuff with good results. Opinions? Thanks.
