ROYAL FALCON – RESTORATION – 2021 UPDATE
It is almost a year since I popped into the Panmure boat shed to check on the progress of the restoration of Steve and Colette Popie’s 38’ bridge-decker – Royal Falcon.So last week I accepted the invitation to view the 1934 Cox & Filmer built launch and woodys its a thing of beauty – check out the finish on the hull 🙂
Launch day is a few weeks away, then the final touches will be done on her berth. The attention to detail is 10/10 but in Steve’s words “its the best of both worlds – classic and modern systems, in terms of safety and ensuring she lasts another 80+ years.

For the petrol (diesel heads) below is a short clip of the Commer TS3 being fired up for the first time post re-build. Owner Steve commented that the puff of smoke is the residual lube oil from the new cylinder sleeve installation 🙂
