The 23 metre Alyssa is an aquaculture service vessel built for Scottish commercial diving and marine services company Leco Marine.  Designed by Argyll Maritime Design Services the Alyssa will perform general fish farm work and is equipped with a net-cleaning and inspection system for the maintenance of fish-farm nets.

Leco Marine’s largest vessel, the Alyssa is an ideal workboat platform with a spacious aft deck, high stability and excellent visibility of operations from the wheelhouse. The large deck cargo capacity and deck crane ensures that lifting and transportation of diving gear and net cleaning equipment is completed with ease. This capacity allows the company to diversify into other fish farm duties should the need arise.

Twin marine diesel Doosan V158TIH engines drive twin 4-bladed fixed pitch propellers via reverse reduction gear boxes. Each engine is fitted with dual station ZF electronic controls from wheelhouse and starboard forward side deck.

The vessel has also been designed to comfortably accommodate three crew overnight with single berth cabins and ample mess facilities.
