ADDITIONAL INFORMATION

Oceansouth began in 1985 in a small garage in Melbourne, Australia as a part-time project making boat ladders and bimini tops. It quickly grew into a global leader in the design and manufacturing of marine accessories. The company expanded its product line beyond its initial offerings, becoming an industry innovator known for blending functionality with style. This reputation for quality led to national recognition in Australia and a move to a larger manufacturing facility in 1990.

In 2012, Oceansouth established its divisional headquarters in Miami, marking its entry into the U.S. market with the aim of expanding its global presence and bringing Oceansouth to the world. This expansion into the U.S.A. was a huge success, leading to further growth in North America and setting the stage for Oceansouth’s foray into the European sector in 2014, with its European base established in Germany.

With our products now sold in 94 countries worldwide, Oceansouth is the premier market leader in marine and boating accessories.
