Yes, standard SUP race board construction I think. Except it weighed more than a house, and was ridiculously awkward to carry. You could buy some wheels for portage, at least in theory (some things Starboard promise never actually make it to retailers). The construction was pretty awful in general - very heavy but still not very durable - although for the last year I think there was a carbon one, which might have been a bit better.
IMO if they'd produced the K14 as they promised, and had improved the construction and reduced the width, it could have been the fastest 14ft flat water board ever produced. But instead they went off on a much less successful tangent once Jim Drake died.
