My only SIB experience is with the 3.8m Zodiac Futura from 2002 in the picture (not me onboard though). I really like most things about the Zodiac Futuras and Classics. I guess at one time SIB basically meant Zodiac, but there are so many newer, possibly more modern, offerings today. There's Suzumar, Honwave, Yam, Excel, Stryker, Highfield, Saturn and dozens more I can't remember right now. Most (or all) being made in China.
How would you say that the more modern SIBs compare to the older Zodiac Futuras and Classics? What do you like or dislike about them? What are the "must have features" today? Many SIBs today seem to be much more reasonably priced than the Zodiacs. I think this boat was around 5000 EUR 20 years ago! My SIB has the alu floor which is great when the boat is in the water ready to go, but it sure adds weight and some setup time to the whole thing. I wouldn't mind if the boat was a little lighter, but I'm not sure I want an air floor either. I guess both would be best.
My Futura came with the steering console and benches but I don't use them. I like to save space and complexity.
Does the newer boats have non-wooden transoms? That would help with rot in older boats. Also transom-tube attachement seems to be different now. What about fabric or floor quality? My Futura is rated for 6 persons and 40 hp which seems to be quite a bit more than most today. But since a 40 hp outboard is not portable I don't think it matters much.
