you can do it but only if you are maxed out with armour food copper for forge tons of wood etc.
you wont get your stuff back for a long time, a long long long time as said by harrison ford in his picture 6 days and seven nights,
I am afraid to say with much condemnation from you lot that as I am in this game so long i stopped just exploring and hoping i dont get stuck like you did so i use that fabulous map maker app and choose were to sail to .
i am currently redoing an old game were i was just advancing by exploring and using the map locations from the stones in the crypts etc and finished up oh bla bla. I didnt take any scrap leather and got attacked twice in a row by the trolls and others and got ruined when finally lost everything near a swamp riddled with leeches that smashed my boat. good fun resurecting this and now really advanced.
but my last game , i used this map creator and found nearby an island which was all swamp , nothing else !! but had cryps everywhere.
so what i did and what you can do is time the sail so you land in day light, then using the map maker head for the closest wooden shack and race there make a bed fire etc repair best as you can, then store your gear in chests and start from there .
I made and got a huge supply of iron etc but such an adventure.
I, and also you, could do the same, find a round stone ruin and start underneath the bottom stone floor.
but you have to shoot out the spawners there first it is very hard but huge joy.
what boat, obviously a karve is it, ??
best bet is for you to try that work bench idea but i only do that at the fire pits to stop the pesky skeletons.
if it is an hour to get to your spot again , it is a, in my opinion, 90% chance of failure so as mentioned earlier by others, find a quiet area nearby such as meadows but highly unlikely.
There are usually plains near the swamps and they are way to hard at your stage so if you can stomach the cheating a bit put your map seed into the "valheim world generator" and work out were you are on it then see if you can build a base near your loot and get it when you have got yourself ready, max armour best foods etc. why dont you put the map seed here and i could take a look at were you might be and suggest a place to go to or better still you do it.
cheers.
extra note, for some unknown reason to myself I don't use portals at all.'

No, you just can have two portals with the same name. So you name all your portals except one "emergency" portal back at your base. You take another one with you, plop it down and it will connect to the only other one with no name.

And you can name them later. If you put a name on a unnamed portal you can still use it for a second or 2 before it deconnects. name the portal at the other end and they connect again.

You can successfully set up on the Swamp shore, but it takes a bit of doing.

1. Launch your boat at the shore at top speed.
2. Jump off, kill everything there.
3. Drop a Campfire, Workbench, or any other spawn-preventing item.
4. Run out of spawn distance.

This will prevent things from spawning near your boat both because you're too far away, and also because spawn-blocking items there are preventing them. Being too far away is important to keep things from spawning along the perimeter of your campfire/etc. and wandering to the boat.

I did this when I needed some extra Iron after mining out my main Swamp biome. I was obviously at a point where nothing in the Swamp was a major threat to me.

Just pray to Odin's beard you don't shore your boat next to an Abomination.

Also, and it's amazing how often people need to be told this: Don't do it at night!

Hmmm, I didn't know that. I'm guessing it follows the same rules as named portals, that if you drop a third no-name portal it will link and the second one will be off?

I always carry mats for a portal on me, and link them to a named portal at my base "exploring". I also have a base portal that is used to connect to many non-base portals; I just change the name to where I want to go, which cuts down my forest of portals to manageable levels. I just put up signs around it with the possible names to remember, but also have their names on map icons I set.

100% this. Find a nearby biome that's safer than the swamp (mistlands, meadows or black forest), toss up a workbench and a portal back to your main base in case you die again, and make a run for it.

If you can't seem to make it, ask some of the helpful Vikings here on the forums for help! I'd be more than happy to run protection for you and I'm sure others would as well. Good luck!

Sail around that swamp until you find a safer place to dock your boat, like a neighboring meadow or black forest biome. Once you're on shore, immediately build a crafting bench and a portal back to your main settlement. Build a wooden wall around it to keep it safe, and then go get your stuff. This way if you die again, you can just use the portal to get back to the swamp instead of sailing.

Swamps are the worst place to have a boat. Leeches will destroy the boat. Plus many of the mobs can spawn underwater with bows to shoot the boat.

Not having any bed close (e.g. on a nearby island or a coastal rock) won't help.

Either move along. You'll eventually return here to find another inventory plus cargo chest.
Or carefully approach the beach from a distance to assess the situation, possibly backwards with suitable wind conditions.

Look out for that swamp, Skipper!

I, also, have made the mistake of landing in a swamp. Don't do it. If you must, your bow is your friend. Use it to kill leeches and everything else in the vicinity before you debark.

I'm not sure why you were trying to build a bed instead of a portal. That suggests you're skipping a biome. Or two. You don't mention whether you were sailing on a boat or a raft, but I'm guessing the latter.

If you're not able to build at least a Karve, you're not ready for the swamps and it will take you so long to recover your stuff that you should just write it off.

#1 - Don't land on shores where you will be killed instantly.
#2 - See #1.

Well...at first I made bed in nearby biomes, of course.

But then I found out that it is way easier to look for Swamp crypts and drive the ship directly to the crypt (10 meters from the entrance), then enter the crypt (safe) and from there eliminate the enemies outside, then build a bed.

But it is right, maybe I should create a first bed in the adjacent biome and then head for the Swamp crypt.

Your first act should be to drop a portal that is linked with your main base. If you don't name the portals, they will autolink immediately once plopped down.

Then you can return to a safe spot where you have everything stored that you will need. Much more appropriate than a bed.
