The rowing club next door to our unit bought a SMALL 3 metre Rib from us to replace an SR4 deluxe as a coaching boat which they felt was too big and it hasn't really worked out for them. From memory it meets your original requirements. if you wish I will go and have a look at it and send you some photies.
From memory it needs a good clean but its all original and in sound condition (i.e no patches) and it goes in the water every weekend. I believe they want £1200 for it another 500 would make it great.
