I was on that coast for a year (1973) on a Navy Patrol Boat. It is a fairly desolate coast line. I think it is FreeRadical who did that trip last year and he may have some tips for you. PM him and see.

Do not try to go into Derby unless absolutely necessary. It is a long way in and out and the tide will beat you.

King George Sound is supposed to be the highlight of that coast but again watch the tide. Google it up and find out where the charter boats go.

When you get to Exmouth, look up Cassa, one of the forum members. He likes his Blues and Booze.

I really envy your trip. Have fun and stay safe.

Thanks Darren
I appreciate the offer and one I will most likely take you up on.
We are leaving Darwin on the 20th, My wife is joining the trip and getting off in Broome so there will be just 2 of us on board after that.
We were hoping to get into King George River on a rising tide, as you know the D40 has 7ft draft but information i have said that minimum water level is 1.5 mts with 3 mt tide. I will survey the area in my dinghy and a mobile depth sounder first. I think this area is to good to just sail past without making the effort.
shoud be in broome around the end of the month.

Fremantle sailing club have published a book which gives detailed information for the whole west coast including the Kimberleys covers everything about approaches and anchoring spots (around $75 but worth every cent) - a must have if your coming down the west coast. Unfortunately my copy is on my boat but can chase up name etc if required
In the meantime also check out this site
www.coastalcruising.com.au
-covers everything up there.
Envious as hell -one day

Thanks All
I have purchased the West Australian Cruising Guide and have now joined th Kimberley Cruising Yacht Club which has some very good information and Anchorage guides on the website.
I still do not have confirmation on depth at entrance of King George River but I will survey it when I get there.
Look forward to what should be a great trip.
