Since your snowmobile trailer features a straight pole tongue, your options for sway control are a bit different than those for standard campers, however we absolutely have some solutions for you.

When you reach highway speeds with a trailer like this, side-to-side movement isn't too uncommon. You could try re-distributing weight inside the trailer (more weight up towards the front) if possible, but to really reduce sway a separate system is likely needed.

If your trailer is equipped with electric brakes, a really nice option is with the Curt True Course Electronic Sway Control System # C94VV. This actually plugs in-line with the trailer and tow vehicle 7-Way connectors and will automatically send small pulses to the trailer brakes in a specific manner to help correct sway on the road. I have attached a short video demonstration below so you can see exactly how it works.

If the trailer doesn't have brakes your only other option will be to install a full weight distribution system with integrated sway control using a pole tongue adapter like the Equal-i-zer # EQ95-01-5950. If you decide to go this route I will be happy to recommend a specific system to go along with this adapter if you can tell me your trailer's loaded tongue weight (or it's total loaded weight if you are unsure).

I have also included a link that will take you to a helpful article on weight distribution systems that you can check out as well.
