With Traffic and also Nomadic you get both WL and full hull per the description. The designers are being coached to add terms like waterline , full hull and scale in their upload titles to guide the buyer.

The web provider oversold its capability so it is a work in progress to inject tweaks to make it more functional. It was a race to get something post SW where designers and buyers could find each other before scattering widely. Fathom has 10 designers who are now adding items in just a month since SW ceased ops. There seems to be strong determination to make it work and improve.
