Hi,

I hope you don't mind a UK blokarter asking on here, I'm trying to get advice from people who are not direct competition (unless some of you are coming over for the Euros?)

I've been blokarting for a couple of years and racing for 12 months in production, the general advice is forget the actual kart, as long as it's straight and the wheels spin freely it's not worth fiddling with, the sail shape is the most important thing.

With this mind I'm thinking about getting some performance batten adjusters (allowed in production in Europe), do you need adjusters on all your sails or are they most effective on the 5.5 and the 4 meter sails? Do you put an entire set on one sail or would it be wise to put them on the lower battens only (trying to save cash )? I was thinking 3x on the 5.5 and 2x on the 4m or maybe 2x on the 5.5 and save one for the 3m if that makes sense?

Any advice would be appreciated.

Hi mate, welcome to the forum. You're most welcome, but might find some of your competition are already here.

I'll leave your question to the Blokart and sail experts though.

Iv'e only sailed a Blokart on 2 occasions and was surprised how little shape the sail had in light winds, I removed every second batten..... much better shape

Now that doesn't surprise me! I've been digging around and prefer the description of landsailers as 'dirtboaters', I'll be using that from now on.

Are you still a 'DirtBoater' if you sail on Salt or Beach Sand?

Our local beach can be pretty dirty... as are some of the racers!

my penny's worth. Forget about the 2m and 3m you will do better by not making any mistakes whilst racing. If you want to save $ or pounds dont worry about the top batten. Haul the sail on and hold the kart down to check the shape. Good luck.

Thanks Arjay.

I've got an old 2m with straps and to be honest I never touch the battens on that as it rips along no mater what in the right conditions!

My other sails have the bungees (old style on 3m and new capped ones on the 4 and 5.5), short of undoing the shock cord and tying a closer knot is there any adjustment to be made? I don't really understand the guides I've read, if I'm in heavy wind I'm more likely to change to smaller sail rather than slack off the battens?! I guess they're talking about fine tuning when the wind is on the edge of 2 sail sizes??

I may wait till after the racing season before I start mucking about with performance adjusters as it'll probably just complicate things.

try threading a peice or 2mm rope through the loops holding the bungee and tension the battens that way, it will tell you if betten tensioners are needed,.
the only sail ive seen with the double bungee was fairly new and it didnt tension the sail eneough with both peices on.
a good guide is if there are vertical wrinkles-not enough tension

with the bungee system you can do as you say, tie a new thumb knot in the elastic to make it tighter.(I have done this on a sail) Another way of increasing the tension is to twist the bungee a few times before putting it on the batten end.
