I did think about this show, but decided against it in the end, mainly because I'm still reeling from it taking 3.5hrs for me to get to the bike show at the NEC late last year from South Hampshire due to traffic caused by accidents and roadworks.
But I'm sure many feel the same way about travelling to the Southampton show which is only 3/4hr away for me.
I'm not going to get to Seawork this year in June due to other commitments, but am considering the South Coast Boat & Green Tech show in April purely to see the green tech stuff:

I know the focus of the show will be new Rag a Stick boats, but the Green stuff should be interesting, and only the parking needs to be paid for.
