@Waxingtonknee @vicarvernon also - the way it works is that the RNLI publish each lifeboat launch with a limited amount of info, I run a program that automatically puts that info into a toot.
Last week I realised the info the RNLI publish includes a boat ID number, that my program can cross-refence in a big spreadsheet of lifeboat data I got from here - https://data-rnli.opendata.arcgis.com/search?layout=grid&tags=rnli%2520lifeboats%2Crnli%2520lifeboat%2520stations
