Yeah, explore with the boat is fine, its relaxing. Mods and world hop is fine too (but need smthng from u, if u need/want to skip). U need to spend some time to bypass. Doesn’t see anything good to player exp in that, just a trouble. Get curios.
I just can’t understand the reason/idea/whatever stand beside the portal restrictions.

The reason is to make you have to actually take things back on a boat instead of only using a boat to get somewhere the first time. It's to create a need for carts and cart-paths. It makes the game take longer and adds in many more sea voyages and some land trips (that can become adventures, or misadventures). I get why they wanted it. I just don't want to do it anymore.
