OK presumably this will be a trailer boat right?
Well for this size trailer boat a glass boat is going to be lighter
Yep lighter.
For a plate boat you need a good deep Vee & deep entry hull design but this will tend to make it a little "rocky" when stationary.
It needs to be a plate boat because of the boat ramps in most places where you chase GTs. With a glass boat you need a jetty or beach to land on to go & get the car, a boat ramp with even small waves will quickly pound a glass boat to death. Coral does much worse
For a boat this big you generally need a boat ramp. You also need a large4x4 or a light truck to tow it with.
Perhaps a tarp to stretch from the centre console roof/windshield back to removable poles for a place to sleep when it rains?
Whatever the boat the deck should be self draining. You need to be able to stand with your toes against the side of the boat & have the padded gunnels against your thighs even if that makes the gunnels fairly wide. There needs to be toe rails along the deck close to the sides to hook feet into. You will be stable to cast regardless of the swell/sea conditions.
You need grab rails for the guys casting, so when the driver is getting in really close to those breakers on the reef he can manoeuvre suddenly without everyone ending up on the floor.
All the other things everyone suggested as well bait/kill tank for the fish you will eat on the overnight trips.
A smaller boat would be better but wont get you as far.
It will also have twin engines and underdeck fuel tanks with a main of say 250 litres and a couple more of 150 litres each under the gunnels on each side
I think in most states the inflatable lifejackets have to be certified yearly and the manufactures usually wont do the inspection (not cost effective) so you may need new ones each year to stay legal.
Mounted on the boat will be all the normal GPS, radios, sounders plotters etc but also an external aerial & charger set-up for your mobile phone. If the budget will stretch then a sattephone as well
Invest in an autopilot. For long trips it si the best investment you will make. It is much safer as concentration tends to wander a bit when you are tired after 3 days of casting & boating lots of 60kg plus fish
Rod storage is always a problem on a casting boat so maybe under the gunnels rather than vertical. On a boat this big its probably at least a 2 man trip so that means 6 or more so rods and even more if its a long way out or an overnight trip.
Would probably go for an anchor winch & chain, since its mainly coral areas and we can use a bigger anchor in the tidal flows when overnighting
We could go one better and use a 7.5 metre "normal" boat and tow a 5 metre dory with only basic stuff
You just need a light truck to pull the big boat and the dory sits on the back of the truck
