The proven dimensions and zero-carbon approach make maritime frames an essential tool for anyone serious about fish preservation.

The History of Maritime Frames

Since ancient times, maritime frames have played an essential role in fish preservation, with evidence tracing back to early Icelandic settlements. You'll find that these structures, known as "fish flakes" in colonial America, revolutionized the way communities preserved their catch through a meticulous drying process.

In the 13th century, Iceland's fish-drying industry began exporting their products, establishing a tradition that would span centuries. You'd see entire communities working together, using wooden racks covered with canvas awnings to protect the drying fish from harsh weather conditions. The fish holding pens on deck allowed workers to accumulate enough catch before beginning the preservation process.

These frames weren't just simple structures – they were carefully engineered to maximize air circulation and guarantee even drying.

The process you'd witness during this time was labor-intensive but effective. Workers would split and gut the fish, apply an initial salting, wash them in seawater, and then add a finer grade of salt before laying them out on the frames.

During rainy weather, they'd protect the fish using wooden boxes or sailcloth covers. This method remained dominant until the 1940s when freezing technology emerged, though you can still find traditional maritime frames in use today.
