It would be interesting to see a 747 with floats, but I suspect that I have to wait a looong time to see that.
But my simple question as the title says: Biggest plane with floats?

That would be the Hughes H-4 Hercules, if I'm not mistaken.

I don't think this qualifies as a float-plane. But I have seen pictures of a DC-3 on floats

Interestingly I saw this quote about the Hercules;
"Some critics of Howard Hughes' massive Spruce Goose claim that the famous flying boat's first (and only) flight was due entirely to wing in ground effect and that the craft was incapable of sustaining flight above a very low altitude. It is probably true that the Spruce Goose was underpowered in its current configuration."

So if we're to take ground effect planes also as possible candidates.

Which was both longer and much heavier than the spruce goose

Definitely NOT a float plane!
AFAIK the C-47(not DC3) float plane was the largest aircraft ever put on floats.

I've found another plane that I had vaguely remembered along with the Spruce Goose: the Martin Mars. What makes this type interesting is that it has survived in active service to this day, so it should be quite an experience watching one of these planes.

I don't think there's a need for yelling - the OP might be interested in flying boats just as much, since he didn't specify "only land aircraft converted to marine use". Wouldn't it be nice if we could simply exchange information on interesting aircraft without fighting over which of them better fits a definition?

The Saunders Roe Princess was not a float plane. It was a flying boat. However it did have retractable wing-tip floats. It is therefore in the mix to be considered to be the "biggest plane with floats".

This four and three quarter minute video tells the life story of the three 10-engined turbo-prop Princesses:

The Beriev BE-200 is a biggy too, albeit not on the scale of the Ekranoplan, but it at least performs as a regular aircraft.

Yep, it is  
Many (including me) see them at the Sproat Lake base, and once on a tour we were allowed to walk and climb around inside.
Also one year a a large Forest Industry Convention in Vancouver, they had one doing water drop circuits at CXH for an hour or so on at least two days, so anyone in downtown Vancouver saw it doing it's thing. Even the non-a.nuts in the office I was in thought it was cool.
Fun fact - CXH controllers could look 'down' at a Mars doing water drops as the tower is over 450 feet above sea level.

I really didn´t want to start an argument of what is a floatplane or not.   My definition is simply a plane that does NOT flot on its own body! The floating is achieved by floats mounted the same way as an ordinary landing gear.
I.e. the Saunders-Roe Princess does not qualify as an answer to my question.

This brings back memories-in 1999, when I was running the VSF FBO, one of the friends I made had several Albatrosses, and he was flying one to the Greenville fly-in, and invited me to come along. I flew my 182, as he wanted to get some air-to-air videos of the Albatross. It wasn't a particularly good weekend weather-wise, but we did get some good air-to-air videos on the first day. On the second day we were pretty much socked in most of the day (the Albatross was at the airport, not on the water) but towards the end of the day the weather lifted enough for us to go down for some water landings. I got to ride on the Albatross this time; we buzzed the seaplane base and went out to land on the open water (the regular landing area was too confined for the Albatross.) We were just landing when several of us saw what looked to be an overturned boat with two people clinging to it dead ahead. That is exactly what it turned out to be, and we rescued them. They were both hypothermic, and probably would not have lasted had not someone come along, and there weren't very many other boats out that day. This incident got a half-page writeup in Flying magazine; it was nice that the Albatross got to again fulfill its original purpose.

So did you ask the wrong question?

You said::

Quoting esgg (Thread starter):
But my simple question as the title says: Biggest plane with floats?

My simple and possible answer was the Saunders Roe Princess.

Note that the Princess was certainly big.

Note that the Princess flew at the Farnborough Air Show and on many other occasions, so it was certainly a plane.

Also note in the video that the Princess was very clearly fitted with two retractable floats, one on the end of each wing.

So exactly how does the Princess not "qualify" to be considered as the "Biggest plane with floats"?

There may be a slight misunderstanding here, or, a difference between swedish and english vocabulary.
From my swedish point of wiev a flotplane does not flot on its body, it uses floats.

A seaplane floats on its body and may use floats on the vingtips to keep balance in the water. But it is
no floatplane, it is a seaplane (or a flying boat).

I hope this clarifies.

Thanks! That clarifies it.

Size-wise, this Italian attempt comes close to the DC-3:
http://en.wikipedia.org/wiki/CANT_Z.509
but it was much lighter than the Douglas aircraft. So perhaps the DC-3 is actually your answer, every larger seaplane that I could find was a flying boat.

I think what the original poster meant was not a plane that built for the purpose of being a float plane - ie Amphibian

The Bereiv B-200, the Spruce Goose, the Grumman Albatross, Goose, Duck, Widgeon, the big flying boats of the 40s/50s etc were amphibians - built as a purpose to operate on land or water.

What the poster means is a plane that was built as purpose to operate from land only, but someone popped on some floats on the bottom - like the various high wing Cessnas, DHC-6, Beech 18, DC-3, various LSAs etc.

Looks like the JU-52/3m beats the DC-3/C-47 in relation to wingspan by a few cm, but on the other side the DC-3/C-47 is the overall heavier plane.

I think the S.20 Mercury would be a candidate. Its max gross (26,800 lbs) was barely more than the DC-3 but it is a smaller plane by wingspan and length. It certainly would win the category of the longest flight ever by a floatplane: 6045 miles.
