How about just casting the other side of your boat until they passed, and then when gone, you can return to where you were casting before. The irritation to you will be gone shortly. It's not like they're static like you.

Casting deliberately into someones boat may cause damage / injury and result in a bigger problem for you.

Also bear in mind it might not be deliberate, they could be trolling a particular depth, or be trying to turn gradually without tangling multiple lines. It could also be you've parked yourself in a prime trolling circuit. Or maybe they troll there regularly and consider it theirs, just like you do :-)

X2 I agree.
