I am an owner of the former Jardine's motor launch "Thistle", now called motor yacht "Isla". She has been restored, and is still running on her original Gardner 8L3 main engine, and is based in Subic Bay, Philippines.
I would be quite pleased to connect with anyone who has any memories or other information about this classic vessel, which celebrated her 50th anniversary last month.
