The Thames 20 rowing skiff is an elegant and very attractive skiff based upon a craft that we originally designed for a client who wanted a simple personal exercise craft which could be used on open inland waters. Construction uses the stitch and tape process with pre-shaped 4mm ply hull planks. These are marked, cut out and then stitched together along the chine seams with scrap copper wire. The seams are then epoxy filleted and when the epoxy has cured the wire stitches are removed allowing the inside of the seams to be glass taped without any bumps caused by leaving the stitches in place. The outside of the chine seams is then epoxy filled and cleaned off - so that no tape is used on the outside chines of the hull allowing a beautiful varnished finish to be applied if required. Although we have not done so, so far, we can produce the mould and building jig details for her to be strip planked in Cedar. LOA 20' (6.1m); Hull beam 26 1/2" (0.67m); Approx. weight depending upon materials and fit-out 70 lbs (32kg).
