If practical, line up with other slow boats ahead of you, so faster craft do not have to weave in and out. Close the throttle or loosen the sheets and lose some headway. Depending on your boat's handling, take large waves just off the bow, or a bit broader off the stern. If your rudder or propeller actually leave the water, it will have been better to have started in good alignment at low speed. The really big waves generally number three or fewer, and you can resume your course and speed very soon.
Longer hulls have to go faster to plane fully.
So, if the offending boat slows down, the wake may get bigger. If two boats are going in the same direction, the faster boat may be better to plane by quickly than to mush by awkwardly. Also, understand the difficulties of getting larger boats up onto a plane. It requires tremendous energy, and then they often have to retune twin engines, trim tabs, and outdrives. Rightly or wrongly, they simply are not going to do this for every boat they pass.
