The ECO 520 is the next catamaran from my jigsaw series. The first was the DUO 480 C.

The clue is, that the hulls can be built laying flat on a table. Starting with the outward hull side.
This makes boat building easier for a first time boat builder.
The boat has a jib rig. This means no high costs for a mast. The plan includes also an easy to build mast.
The double jib rig can be handled from the safety of the cockpit. The boat can be easy trailed too.
So the total cost of building the boat and the running costs can be kept to a minimum.
