    dual H2O pick up rudder

    I want to put on a dual pickup rudder. I would like to put on a longer one. I have been reading where a longer one will help with chine. Is there a longer one avaliable that will bolt on to the existing stock bracket? If I go with a longer one, with a aftermarket baracket, will the stearing push rod from the servo still fit? If not, what do I do?

    The place where I got my rudder (and other stuff too) is from Off Shore Electronics. They have all kinds of goodies for our Spartan boats.

    Thanks, I have been looking on that site. will a longer rudder help with chine? If I go with a different mounting bracket for the rudder, and it is farther back than the stock bracket, I will need a longer stearing push rod, correct? Where do I get one or can I make one?

    Chine walk happens because the boats COG. So, a longer rudder will not help. A heavier transom however could help if you have too much weight too far forward.

    Deep V's should have a center of gravity of 27-30% of the length of the hull on the back half of it. So first I would try to find the closest COG to 27-30% of your hull length, and then from there adjust batteries until you get close. If it's still too light in the back, a heavier transom would help with chine walk. A Heavier transom could include a bigger rudder.

    I have always wondered is the CoG measured starting from the rear to the front? I would think that makes sense, no?

    Its funny how the more I shift the batteries towards the rear, the faster and more stable it gets on calm water. I figured it would get faster but didnt realize about the stable part. Like you said, the chine is much less as well!
