Do a check on your fuel usage. 280ltrs should get you out and back , even an over-nighter, easily. A good return trip will be about 200 - 250k's
Easter is prime time at 1770 / Agnes Water and everything is at a premium, accommodation and parking in particular.
Options are... launch pre dawn or midday.. pre dawn gets you parking, midday gets you no crowds on the ramp.
Where would I be going you ask.
If you answer some questions, I can provide the info.
1.. Target species ?
2... Over-night or day trip ?
3... Deep water or shallow ( shallow = up to 50mtrs... deep water 65 - 100 )
attached is a " trip ". I pre do many trips like this to determine distances etc. Some times is it best to out " into the seas ' and return with the wind up ya clacker... NE should be the wind at Easter, so heading to Fitzroy area is on the cards. I have a bucket load of GPS points for all over the shop up there, if you need starter marks.... the really good ones will be exchanged for next weeks lotto numbers
