Hi George, I hope you are fit and well. I've still got the drawings of "Cervia" and intend to start on it but I've come up against a lot of domestic resistance for some time now. I'll give it another go when the weather warms up, this time with ear plugs in. As for the Sun tug, I like collecting and studying tug plans, although the words "Tug" and "Plans" dare not be mentioned here. Best regards, Geoff.
