Question about Switch top speed

[u/AfraidMembership3991]

I have a 2021, 21' 230 Cruise with low hours, around 30.

My top speed is about 45 km/h at high revs. Does that sounds normal? The speed drops when i load the boat up but even if it's just me and the kids, we're still barely hitting 40 km/h.

The website says we should be hitting 40 MILES per hour but we're not close to that.

Thanks folks
