I'm a newbie of boating, wanna purchasing a Zodiac boat, but I can not figure out the difference among the Zoom, Cadet, Typhoon. I was told that the wooden floor is easy to be dameged by salt water or be cracked by treaded. I can not find aluminum floor in the above types. And the air floor is enough light to me to lift it to the car roof, I pretty like this type, but I still worry about it's stablility and the direction controlling. So maybe someone would give me some advice. (I have 4 persons (2+2), so the 260 size is perfect.)
