Of course there is brewing...and then there is Brewing.
If just brewing a drinkable beer is the goal, and you have access to hopped malt extract, then you can just do dump-and-stir brewing with no boil required. Easiest, cheapest, least equipment
, and least energy consuming. Best option for a boat I think.
But, if you really want to get into serious brewing...then things get complicated and beyond what is reasonable to do on a small boat I think.
With dump-and-stir, aside for acquiring the hopped malt extract, the main problems are reduced to storage
(malt extract at the least will discolor in poor storage
conditions, but hey hitting the stylistically correct color is not a goal anyway) and fermentation temp control.
A perfectly acceptable beer can be brewed using bread yeast, which is available almost anywhere. No need for specific pure yeast cultures if you are not trying to nail a style.
You are not going to make an award
winning beer this way, but you can make a perfectly drinkable brew.
If I were to brew aboard I would probably brew mead. Yeast and honey can be acquired almost anywhere. You can make the needed yeast nutrients from denatured (boiled) bread yeast...and you're in business with no importation and minimal equipment
requirements. Of course, slugging down a glass of mead on a hot day is not as appealing as a cold beer. ;-)
Here's another tropical hooch idea for you. Pineapple, like many sugary fruits, has natural yeast which live on its skin. Effectively making it a nice little self contained hooch brewing package. You can crush pineapple in a pot (husk and all because that's where the yeast live) with some non-chlorinated water and it will spontaneously ferment...no need to import
anything or use any energy other than muscle power.
