Cape Ford is your best bet and there’s a couple of creeks south of Pt Keats at Fossil head

Gday Mark, Generally speaking u can access most creeks and rivers on the top half of the tide even lower in many cases, sandy gutters with in the creek  and river mouths are pretty much the norm,  there usually easy enough  to find can also shift from year to year with the big tides . If unsure, steady as she goes on an incoming tide keeping an eye on the sounder,  once in u can normally find a deeper hole somewhere suitable to tie off (mangrove trees). I also think some of the gorges ( fitzmaurice, king George, Berkeley) etc would be suitable depending on the situation, rainfall to date, river flows etc  There’s some pretty good weather apps (cyclone tracking)  etc u can download, giving u plenty of time to stay ahead of what ever may  eventuate. Mid April onwards highly unlikely.     cheers. Steve

Gday mark,  There’s a couple of creeks not far from Fossil head just south of    Port Keats   cheers. Steve

Perfect   The doldrums (build up type conditions) usually hang around til early may  . Good idea to get across the blownapart gulf before the south Easter’s kick in, minimal chance of cyclone that late in the wet.            cheers.    Steve

Gday snow                                                                                                                Id reckon the best way to make any comparisons on which material (core) is the best choice would be to count the amount of boats above the 8 to 10 metre range that are made of aluminium in any marina any where. There are many reasons why fibreglass is the preferred choice, pick up a sheet of 20 ml thick duflex with either a balsa or foam core then go pick up the same size 2400 x1200 sheet of 3 mm aluminium and see who wins,  fibreglass/ composite boat construction has come along way in the last 20 plus years, resin infusion , vacuum bagging, duflex kits etc all aimed primarily at weight reduction. Positive bouancy, insulation properties, (much cooler in tropical climate plus less noisey, no corrosion (electrolysis), more paint choices both above and below the waterline, easier to repair if you punch a whole in it, not  every one can tig weld specially not parked on a bit of reef in the middle of the Kimberley, most people can glue to bits of wood together though             Respectfully.    Steve

Legends. We tend to be pretty good these days at finding excuses as to why we can’t do stuff. With big mobs of common sense, some know how and just a little bit of gumption it’s amazing what we can achieve if we want to.            Next trip you’ll be launching at Wyndham (late April early may) and having someone pick you up in derby. Well done

Gday snow,I to was faced with this dilemma also. I have lived in Darwin for 30 + years and been a keen fisherman during that time, we all pretty much started out with 12 foot roof top tinnys in the day and slowly progressed to 4.5 to 6.0 metre and even bigger plate boats(expensive) so as to access more remote fishing grounds. Having sailed the whitsundays on my brother in laws 40 ft catamaran I started to learn catamaran design both power + sail advantages pros and cons for both. I no zip about sailing and wasn’t prepared to go there but did learn that it is quiet common to convert sailing cats to power cats especially in parts of Asia and to a lesser extent on the east coast. Lots of sailors make the transition from sailing to power as they age. It absolutely is a buyers market for such a project and hull extensions ( adding bouancy aft)  is the only major difference between sail and power catamaran hull design. Which leads me to my current project which has been briefly  explained on a similar type topic on this web site. Most of the sailing community will tell you that because of the nature of the Kimberley, rivers, gorges, hazardous conditions(reefs, bombies,tides) etc they spend most of there time motoring. So for me it was a 10 metre power catamaran with twin 20 hp Honda outboard motors, super light (2.5 ton) which translates to super efficient and economical motoring be it 8 knots on one engine or 12 to 14 using both,1.5 to 2 mile per litre + all the other advantages that catamaran design offers. Hope this helps, cheers  Steve
