       2. I am happy to report that the pontoons built in 2007 are still in good condition
          and the erosion in the banks is smaller than predicted during the design stage,
          therefore I am willing to upgrade the berthing wet length capacity from 6m
          to 7m and wet beam to be 2.5m. Making it possible to tie the resort’s boat
          shown in Picture 2.




       3. Pontoon capacity was re-asses using Pile design using AS2159- 1995 “Piling
          – Design and installation” and AS3962-2001 “Guidelines for design of
          marinas” Even tough pile design was identical for both pontoons, there was
          less erosion under the east pontoons making height above sea bed shorter.
          Bending loads are smaller for this pontoon, I recommend therefore to berth
          larger vessel to the east pontoon, when possible.
