Keith I have no idea when it comes to price, but this time of year there are many people trying to sell boats for the end of the season so it is a buyers market.
What I will say if anyone is interested in the Humber. I bought my Ribcraft from Woody this time last year and it was meticulously maintained and in great condition, in fact after the sea trial the engine was being flushed before he even offered me a cuppa! Having kept in touch and knowing his trade and how pedantic he is it will be in great shape. Best of luck
