Its a 15 foot Lone Star with a 35 Evinrude.

Oh. Well.

If that's what you're in then any of the 18 foot+ bowriders would be worth
considering. And if all you're concerned about (watersport-wise) is going
tubing then something with an outboard is likewise worth considering. Going
with a wakeboard or waterskiing inboard Mastercraft might be overkill.
What're other folks on the nearby waters using? Might want to consider
going along with whatever's popular locally, if just to have good dealer
support (if you're considering a new or recent boat).
