If you go for a bow saw (which I'd suggest for logs this size given the cheap price and ease of use/lightness), get one with the correct blade. Rakers have already been mentioned - something similar to
this one. If the saw doesn't come with one just get a replacement blade. It makes a surprising amount of different, especially when cutting green wood.
My understanding might be faulty, but those raker teeth look mostly for show to me. As I understand it, raker teeth on a crosscut saw are set just below the tips of the regular cutting teeth, so their tips score each side of the kerf, and the raker like a chisel cleans out the separated material. Those are so high up they won't touch anything !
A quick search seems to indicate that all bowsaw blades for green timber look the same, with raker teeth shorter than the regular teeth. Have a look at
this which I just found from the US Forestry Service. The picture part way down shows the rakers as shorter. I guess that makes sense - if the raker extends above the cutters then they'll be trying to rake out fibers which haven't yet been cut.

I think I've made my feelings about bow saws known already. I'm willing to accept the possiblity that good ones might exist, but the common sort are not very effective. The tooth line being below the line through the two mounting holes in the saw blade means any downward pressure and it won't saw straight. But the cheap saws are so light that they don't make much impression without downward pressure. Combined with poor blade clamping and inadequate tension, they are just a source of frustration. I threw mine in the metal skip and bought a 1 man crosscut from Thomas Flinn. Once properly sharpened thay are fairly good.
We use bowsaws regularly at work (with the Wildlife Trust). I think they're made by Bacho and most are fitted with the wet wood blades. If you make sure that you change the blade when they get blunt and make sure that they're tensioned correctly (our models have a screw tensioner) then they work well. In the past I've used them for felling 6"+ diameter oak trees without too many problems. We also use them fairly regularly for cutting gorse and it goes through pretty well.
