Last two goes I have either have had large waves slop over the side of the boat going round corners causing instant soaking or water come down the neck of my hood. It's Popeye situation where waterproofs make little difference in soak level.
My solution is a second set of clothes but not many of the GP know what they are in store for
Exactly. The corner wave slopping really is bonkers. At least after a ride on Popeye you're in a warm country. This Summer I did a couple of water ride sessions on nice quiet evenings in IOA: Popeye once or twice, Jurassic Park once, Ripsaw Falls twice (what a ride). Utterly soaked. T-shirt, swimming trunks & sandals on. Enduring the epic walk back to the car and short drive back to hotel was just about bearable. There is no way I would come off Valhalla in Blackpool and arrive home an hour later like a drowned rat without changing.
A couple of seasons ago, I realised I hadn't been on Valhalla for several years so decided to make up for lost time, push the boat out, go with full golf waterproofs & wellies & ride it as many times as I could stand, with change of clothes in locker just in case. Unfortunately I was yet to learn what
@RoyJess has said about the neck of your jacket. My feet were bone dry in the wellies, but something, what surely must have been the vortex, I forget, sent water pouring down the gap round my jacket neck, down my back and into my duds. So, with full waterproofs on, I still ended up changing my t-shirt and undercrackers. 6 walk-on rides back to back and I'd had enough, felt like a block of ice.
Great tip about pulling your jacket neck tight. Also, I pull my knees in if only to stop them getting a killer bashing on the boat sides. I generally only go on these days if the kids want to, but even then I'm reluctant. Dragging 3 sets of spare clothes & shoes about or having to get a locker (I am a Yorkshireman, remember) is just a pain. I never remember getting an unbearable soaking on Log Flume. There was nothing to complain about with that ride. No effects to go wrong. You got a great view on it too. How I miss it.
