I took our Marauder 27 with an air draft
of 11.3m up the Hawkesbury River all the way to Windsor several years ago. If you can get under the railway bridge 11.5m high water
springs then it is possible to explore this area. However a 39foot boat is likely to have a much higher mast
unless in a tabernacle and able to be lowered.
The river is tidal all the way to Windsor and there is enough depth
for a yacht as long as you stay to the outside of bends.
It is quite scenic to Wisemans Ferry
with sandstone cliffs and little habitation. Past this point it becomes much less scenic meandering through low fields. Avoid the weekends since there are many water
ski boats around some of whom take great delight in spraying you with water. Perhaps it is just their friendly gesture to cool off yachties on hot days.
Once under the rail bridge there is the M1 road bridge 11.8m to contend with and thereafter a number of high tension power lines that are much higher.
If you cannot get under the rail bridge there is still a lot of waterway up Cowan Creek and Pittwater to visit. It is 60 NM from the mouth of the Hawkesbury to Windsor. Alan Lucas book on the Hawksbury gives a lot of detail with maps.
