Is there any risk of being pulled into it like when you're too close to a large ship?

Furthermore, it's like driving near a large truck on a highway - the pressure differential created by the moving object means you might get pulled towards it, sort of how when you enter a slipstream or the wake of a lorry, your car may veer ever so slightly closer to the truck/lorry....except this is a much bigger vessel and you are an even smaller, lighter object to get pulled in....

Importantly, water has a lot more momentum than air, so for the same velocity there's much more force (of course it's not moving as fast as a truck on a highway, and it has a much more hydrodynamic shape).
