Hhhmm.. We cruised from the BVI
last year and NEVER had an issue with connections. The only place that couldn't fill our 2 standard 20lb propane
bottle was in Martinique
. However, there was someone there that did it "under the table" if in an emergency
. It wasn't an issue since St. Lucia was 25 miles south and propane was readily available in Rodney bay.
I'm not sure where in the Caribbean
you are cruising that you are having trouble filling standard North American bottles?
