Nice job on the tillers. Your brackets are a nice touch - able to keep the tillers out of the water when the boat is well heeled but still allow you to move them up and forward when sitting further towards the bow. Nicely done.
What is your impression after having sailed the boat with twin tillers?
My first reaction was forgetting I had 2 tillers but once I got over that, they seem great. The main reason for me having 2 is that my boat handling skills suffer in high winds and it's mostly due to tiller f'k ups. It gets stuck under hiking strap, tramp or wrapped around kite sheet. The support brakets worked fine. There was no real added friction. But the thing is that I haven't tested it yet in wind conditons I want. I'm also worried that those supports are looking to snag a kite sheet as well. so we will see.
