Yes... come alongside the buoy and pass a line through it... (they have a ring on top of around 3" diameter), and then motor gently into the pontoon, either bow or stern too as required...
The buoys are a good long way from the pontoon (60'?), so its a lot easier than it sounds.....
My technique when going bows too was to put the bouy alongside just behind the bow, reach down and feed a line through (the buoys are conical and the eye on top is a good 18" to 2' above the waterline), take the slack out of the line and then use this (under the control of a crew member) to control progress in.... the line below the buoys are weighted, so they fall straight down and therefore no fouling risk....
This year, I intend to try stern in, so I'll follow the process in reverse, and hope that my steerage remains good enough! and that a gap exists, and i've not got to force my way in, otherwise it'll be bows too!
i'd never done it before when I first visted Oostende 3 years ago, and found it really quite easy.... (thats guaranteed a complete mess of its this year then )
