It appears like your battens are too tight in their pockets, they don't need to be tight and should be loose so they can 'pop' in tacks and gybes.
Have a try and get back if the problem isn't fixed!
Also, more info about the boat is available here...
I am Laser Class Captain at the Royal Harwich Yacht Club (Suffolk, UK) and I know that we are certainly taking part! I hope it will be a great event (both globally and locally) in honour of a fantastic sailor.
During 2013 I was stalked by a seal on a few occasions, once the seal popped up behind my transom and looked like it wanted to join me in the boat!
However it prefers stalking my Mirror Dinghy - it once followed me for around 20 minutes - following me upwind and downwind!
It has climbed into...
I've done a bit of snow sailing before on the East Coast (UK), it's great fun but you certainly need a RO who understands that races must be short and happen almost back to back - plus rescue boats on hand!
