Yes, there's even a high velocity, small duct Unico System designed specifically for marine applications that outperforms other systems! This compact, efficient system is excellent for applications such as:

While most systems use large ducts and registers to dump air into conditioned compartments, the Unico System utilizes a set of tiny flexible insulated ducts that discharge small jets of air through 2-inch (50 mm) diameter holes. Not only does it provide the benefit of reducing fan power, it provides positive air mixing. The system effectively removes 30% more moisture in the cooling mode than conventional systems, providing a higher degree of total comfort.
