This is a regular and well-respected event at the Haydock Park race course which is well located in the "South of the North" just off the M6 near Warrington. Lots of model boats and model traders all together in the very good facilities of this race course. (Even a couple of small pools which are fine for smallish subs.)
Probably your only chance now in the UK to exhibit on a subs only stand.
A good chance to show your subs (r/c,static, kit etc etc) to the public and fellow modellers.
(More details and photos of previous shows on the this Forum.) (You need to be a registered AMS member to exhibit but it is free to do this online on the AMS Website.)
So get building now! Although part built attracts more interest.
