First falls on double occupancy in the water of significantly depressed high ground on -between the Sitzenden- as an air mattress, where the front and back of a draufsetzt (in our 59 + 85KG).
Then the airship is so wide that my existing, very good double paddle grinds while paddling on the side tubes or I have to do to prevent this unergonomic contortions.
The performance figures are compared to my "real" Kayak in total in what felt like about 50% (hab's not measured), due lousy water release (like a firmly sucking air mattress) and high latitude and despite extra-purchased extra rudder; ergo zero driving pleasure on my part.
Because many euphoric vote my way too high expectations have been but then disappointed.
Who's not better known and / or 'time on the beach with no wind and a bit of will on the water without wave action, but can have fun. Qualitatively affects the whole of the first and second look fairly decent
