after rowing ashore, I see a group of heavily tanned, white haired guys on the shore, heatedly arguing about solar panel output and charge controllers...all kinds of numbers, decimals, jargon and acronyms being bandied about...and I keep walking by, watching the antics, but not sure if I should join the fracas, just for fun

Instead, I get back in my dinghy and row back to my boat and have another cold one, chilling in my milli-amp drawing Engel fridge/freezer ...
