Japanese 14m Daihatsu Landing Craft

Hi there,
I'm having a go at doing a Japanese WW2 Landing craft, of the 14 metre Daihatsu type, as modelled by Mokuzu Dock, as found here :

‘å”*ƒ_ƒEƒ“ƒ[ƒh

Here's the parts


And here's the instructions

But I can't work out how the lower hull skin (22 & 23) fits over the projecting formers (parts 2 to 6). Is it a case of somehow shaping/bending them over the W shaped bow give the unusual design that you can see below.



Any suggestions/insight you might have is very welcome!
Thanks
Julian
