The 3.2m Honwave is a great choice, I had one for a season with a 15hp 2 stroke Mariner, I loved it.
Dont worry too much about the size, because it has a flat front and only stubby cones at the back its actually nearly as big inside as a 3.4 Zodiac. It also feels 'safe' because the V floor and big tubes give it a much deeper cockpit than the Zodiac.
I really liked ours, the only downside was the weight and the fact it was too big as a tender for our sports cruiser.
Other manufactures that produce V floors are Suzamar and Wet Line.
