Very cool sensation jumping in the dark as you don't know when your gonna hit the water!
and this is where you can get hurt badly...this is why I don't do it...you need to have the right tension in the legs when landing...
Jumping at night is possible and fun. I have night jumped on my landboard In the sand dunes on a hill with 3d terrain. That's certainly a lot harder to land than a flat water spot. You need to land it properly or you hurt. In the water stuff up a jump.... 99% if the time who cares, its just a splash down.
It is a very serreal and zen like thing to do. sure you can't spot your landing as easily as during the day. But you can "feel' When the land is approaching. You must fly relaxed and ready to absorb the landing at any time
But it is possible, highly thrilling and very saticfying.
Toby you most certainly can jump on the water, land sweetly and bust out basic tricks if you want. I challenge you to try again. Basic tricks that bore you during the day will thrill you at night.
