I Googled "Redmond Whisp" just now, not having heard of the boat. Here are a couple of things that turned up. Hope they help.

Redmond's Whisp skiff, and John Marples' 23-ft Cyclone trimaran (Constant Camber). Happy to share any information with potential builders of these boats

Jim,
Construction details and finishing of the Whisp are covered in the book "Ultra Light Boat Building" by Tom Hill. This boat is going to be one of my future projects somewhere down the line! Of course... If you'd consider trading your Whisp for an already finished Light Dory give me a shout! Jake
