As much as we love the PAULA III model I think the description has always been of it being a "representative" of anything common out there was a bit wrong and no salt chucked over the shoulder provided more alternatives we could squint and ignore anywhere.
It remains a toy boat albeit quite versatile...
Today I stumbled something on a website sales site (I can't get to the original listing as the boat is now sold) but it's worth sharing I can find pics from google images.
CHICKEN OR EGG????? It seems there is a prototype out there for everything after all??!!
