Being spoiled having owned a Nautique I wouldn't call anything like a RIB or SIB a good wakeboarding/waterskiing boat. The smaller and lighter you get the easier it is to pull around. If you aren't going to be trying to run buoys, you can ski behind anything you can get up behind, but if you need 34+ mph (55kph) speeds (depending on rope length) well, the boat better go that fast. Wakeboards allow you to get up behind almost anything with at least 15 hp. Again the boat has to maintain 24.2 mph (39 kph) to really ride hard, but if you just want to screw around being able to go 20 mph (32 kph) is a good thing. The rider will be able to pull the back end of the boat all over the place, but it can be fun to go out and land some tricks behind a tiny boat just for fun. I was able to land air rolls, etc behind a 13 Boston Whaler with a 25 hp motor. I could also almost stop the boat with a hard cut, and turn it 45 degrees LOL
The 25 and 30hp engines are going to be tough to handle with just one person. They are heavy! The boat also only folds up so small, but should fit into one of the compartments on your caravan. Do you drive your camper or tow it?
The glue on older Zodiacs will fail, not typically the tubes as they are thermo welded. The poster above had some unusual stuff happen (Of course he could have sold parts of the boat had he not cut it up). Worry most about the glue!
Personally owning a SIB there are many times I wish it would morph into a RIB like yours
