Two problems with the rope system:

1. in the picture you can see the line is chafing already. So, you have to replace it and keep an eye on it.

2. You still have to go to each side of the boat to get them both up and down, which is not always possible if it's blowing and you are comming in to shore fast, in surf. You can easily flip if you go to the low side of the boat to unclip that rudder. F that!

All you have to do is get someone to build the Nacra system in carbon fiber so you can just lift the cross bar, both rudders pop up, you can put them back down by pushing back on the cross bar, without having to go to the low side at all.
