AN old issue of Model Maker featuring the Riva Ariston on the cover, triggered off the design of this model, which is 28 in length. The original used a Taycol Meteor (mounted on its side) but if two single seats were fitted forward it would be quite simple to mount an ic engine of, say, 1½ cc, between them.

Construction starts in the conventional way by tracing and cutting the keel from 1/8 in ply, allowing for the prop tube. Cut the 6 bulkheads and slot them as shown, and add 1/8 in ply doublers to the keel fore and aft of B3, for the prop and rudder tubes. Assemble the bulkheads to the keel and add chines and inwales; when dry glass-paper all edges to provide a fair seating for the 1/16 in ply skins, especially the V of the keel in the region of the doublers. The skins on the original were attached with Britfix cement, with a few tiny brass pins where necessary.
