valheim raft, a better wat to get in and out of the boat

so, with Valheim raft mod and self built custom boats, you can play nomadically and take your base with you, but getting in and out of the boat with rope ladders is both annoying and dangerous, you can fall, losing stamina while swimming, and even drown while trying to grab that rope ladder. So instead I built a way to just swim and walk in and out, works 100% of the time, no falling, no climbing, no drowning. apparently the game does not care that the back of my boat is wide open. you just leave the back open, and build stairs two levels below the hull waterline.

it's a simple boat for now, but I am still in meadows, just raided the edge of black forest for core wood for the masts.

i wonder if there is a way to hinge this, like a drawbridge entry plank you could raise and lower? i don't want to be tied to permanent docks, best to be able to sail and get on and off anywhere. like a amphibious landing ship, sail to shore, lower the entry plank, walk on and off without swimming?

I'm playing with fire spread on, so a fire inside my boat will burn down my ship. Later, i will be able to build a stone or iron fire box, but for now to sleep and rest, i still need to go ashore and get inside a basic building.
