I am a fellow 4000 sailor!
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!
It wasn't even that windy! I just tacked and bang! I had been out last week in much stronger winds, clearly weakening it. I just bought a brand new rooster sail, so lucky that I didn't put that on yesterday! I still managed to do the 2nd race, borrowing a top section and a top batten, as mine...
