Hi Boat Crazy, welcome to the forum.
The SWMEE show is well worth a visit, it was it's first year last year and was well organised and it can only get bigger.
There was only one issue that I heard of regarding the distance to the lake for sailing, there was a mini bus shuttle running all day to the lake and flying area, but, as I understand it has been resolved and the organisers are erecting a portable pool.
I (MMB) will be there all weekend this year why not come and say hi, I will be the one hiding behind the fogbank.
Mark.
