The Swift 6 metre dayboat was commissioned by Mr. P. Roberts who wanted an easily built boat similar in line to some of the French dayboats. In fact, she is also similar to boats of the Gareloch and Loch Long classes raced on the Clyde. The drawings show full details for her construction using the easy stringer/clinker plank method as used on the Islay design but she may also be built using the strip plank method or a drawing can be produced showing plank shapes for stitch and epoxy. Mould sectional shapes are erected upside down on a building frame. The keel structure, transom and stem are then temporarily fastened in place along with the stringers. The ply planks are then applied oversize and trimmed to the shape dictated by the stringers. The chipboard mould shapes are all computer faired so that there is no need for lofting and details are given for hollow wood spars. LOD 6m, 19’9’’; Beam 2m, 6’7’’; Draft .45/1.1, 1’6’’/3’7’’; SA 16.4 sq.m, 174 sq.ft., Weight 750 kg, 1653 lb; Ballast 210 kg, 463 lb. Details are available for a deeper keel and cuddy version (without the centreboard) and a version with greater internal volume and an inboard engine.
