The ocean, even if divided and named such as Pacific and Atlantic, is big water. The biggest. Covering something like 70% of the earth, this massive amount of saltwater usually requires a big boat because of the intimidating scale, giant wave potential, powerful currents, and such. However, small boats venture in saltwater frequently mainly because of the tremendous fishing opportunities. The smallest boat for ocean fishing has to be the ocean kayak.
Smallest boats for ocean fishing
Sizes of offshore kayaks vary by intended use. As far as the smallest boat for ocean crossing, perhaps paddling to islands or completing long distances for camping down coast lines, the longer, narrower, touring sit-in kayak models often are well over 20 feet long. The smallest boat for ocean fishing is shorter and wider with sea fishing kayaks, often sit-on design, running around 12 to 16 feet. Both types can be light enough to be carried by hand, or at least hand pulled on a small cart to help with assorted big water gear. While investigating the smallest boat for open ocean or smallest boat for ocean crossing, one may find sailboats of wide ranging lengths mentioned but these are heavier and not designed for fishing efficiency.
Fishing in the smallest boat size for the ocean is risky so take ample safety precautions such as watching the weather, gaining experience close to shore first, having everything on your safety equipment checklist, and if going out alone, at least letting someone know your float plan. Choose your craft wisely to best handle current, swells, and unexpected waves while battling fish that could be large enough to tow you around for a while. The smallest boat for ocean fishing should also have storage below deck, the ability to rig everything to handle flipping, and some type of rudder for paddling efficiency over great distances.
