The Haines 16R is a great allrounder boat. And is capable of skiing and leisure work towing tubes etc. just keep the power up to them. A 115hp would suit it well.
If your not venturing out into the wide ocean and will keep to smooth waterways. Then just about any 16ft boat will fit the task. An older signature, cruise craft, or even the lesser known brands will do the trick.
