The boat views only use the OpenStreetMap `boat` tag. If a section of river is missing from WWM.org, then it's likely the tag is missing from the OSM waterway. You can fix that!
Hmm I investigated that and the missing sections on OSM are indeed tagged with boat: yes and motorboat: yes. I'll do a little more digging
PS. Despite using OSM for many years, I've never looked into editing it. Thanks for giving me the impetus to start! There are bits and bobs I've noticed aren't entirely correct as we move around the country, and now I'll be able to fix them where necessary.
