Am trying to research building a model of the Daman 4207 Patrol vessel, used as the base for many coastal patrol vessels including HMCC Vigilant & Vailiant. A similar, slightly smaller vessel was build by Vosper as HMCC Sentinel etc. Both of these vessel types use a mid-hull mounted stabilizer/rudder at about spray rail level linked to the actual rudder. Understand the purpose of this stabilizer is to reduce roll in turns. Does anybody have any details of these items and particularly how they are linked to and work in conjunction with the rudder?
Thank you. I want a working system and was thinking out attaching them to the rudders. The operating ratio could be easily adjusted, but the gyro suggestion is novel and intriguing. Will investigate as would be an interesting feature.
Hi I helped a friend build the Sentinel from Model Slipway. The stabilisers are connected by push rods to the rudders and do work well in preventing the model from listing heavily in fast turns. I no longer have access to the model so can't provide a picture of the linkages. It did require some fetteling to get the setup correct but the end result was justified. Both stabilisers are linked together by rods that run to the rear and connect with the twin linked rudders. If you can source a plan from someone I do recall the details were given. Cheers Dave
Thank you both for your help. That site has some very useful pictures to explain how that vessel installation is rigged. The suggestion to use a gyroscope is intriguing, going to explore it. The installation might be simpler, although the control is some thing I have never tried before.
a board that can and will use an accelerometer to control servos to move your stabilizers he explains how to setup your board. While not intended for boats the naze32 is a really complex and effective board intended for drones etc.
