I don’t want speed, rough wat r handling.  I want a big platform and storage.  Who else fits the bill

Clearly I'm bias but this rig would fit the bill.

Bass Cat first comes to mind then Skeeter. the best riding boat I've  been in is a Charger,used to be Champion. 

Everything I have read us bass cat built for speed and rough water

Bass Cat, Skeeter, Triton, Phoenix, Nitro, Procraft, G3, all have 21' boats with lots of storage and room.  There are probably a few more also that I forgot.

SeaArk makes a couple big aluminums. Depends on what you want it to do.

I guess it's going to boil down to how much money you want to spend

Bass Cat Cougar is a dry running hull in big waves and very popular on big lakes. The fact is has good storage and speed is a bonus few bass boats can offer today.
