The vehicles section on dndbeyond doesn't contain all the vehicles from the books, it doesn't even contain the vehicles from the srd. I was trying to find boats to buy during a campaign and they are scattered around some being in equipment under vehicle(water) others being classed as adventuring gear. Please hire a rogue with expertise in investigation to sort out your checks and have them put all the vehicles in the vehicles section.

There are two types of vehicles in D&D; those with stats and those without; with the former being listed as Vehicles (with a capital V) and the latter as Equipment. For example, a galley has stats (found in Ghosts of Saltmarsh) and so appears in the Vehicles listings. However, a sled does not have stats and is thus listed as equipment.

Until WotC publishes Vehicle stat blocks for the other vehicles found in Player's Handbook, they'll remain in the equipment listings.

Any chance of getting the statted Vehicles added to Encounters? My table went whaling a few weeks ago and tracking things for their Sailing Ship was… interesting.
