SmallBoatLover: It's an Albin Vega. Swedish built. The only ones over here have come over on their own hulls. The only other one I know of I last seen in news footage last week floating down a flooded river whilst still attached to it's finger pontoon along with another 3 or 4 boats!
Where are you located? You must get extreme tides by the looks of those floating dock pilings?
Mackay, Qld, Aus. We get about 6m / 20ft on the biggest springs but the piles need to be higher as well to allow for storm surge in the event of a cyclone. Down south a little ways - maybe 100 nm - the maximum tides are 10m, which are the highest on the east coast of Australia. The Whitsunday islands are about 50nm north of here and the max tides are about 4m.
