The upper half is available separately to drive a custom trimtab on a boat with an outboard rudder. The trimtab is not provided by Scanmar International because size and design change from boat to boat. Some experimentation will be required. This is a simple and economical system for the sailor who is handy and does not mind making part of his windvane himself rather than buying a finished product. The auto-helm windvane s customized attachment system makes installation easy on most boats.
Installation plans for hundreds of cruising boats are on file.
Send us as much information as possible about your boat. We will make an installation drawing and mounting recommendation at no charge or obligation.
