Codprawn - yes, it's based on an 8.5m osprey hull, but it's self built by the owner. It has the tubes fitted further out than standard to give more internal space , a lower deck fitted, a Scorpion console, and is powered by a Yanmar 300 through a Bravo1 drive.
Boatster - I'll have a video of the seagull which may be a distant cousin of your seagulls! I'll upload it to our site at the weekend
