DONE!! Thanks to those who offered and who brought chain along on Monday night. We made a selection, and the job is now done.
It would be advantageous to be able to swing our pontoon around to provide more points for tying up boats during regattas etc. To do this we need an extra anchor point with a heavy attachment chain. Three metres would do the job. Anybody have said tripping people up outside the back door? if you do contact the secretary: firstname.lastname@example.org
