Stern thruster(s)
One of the things we’re going to add is a stern thruster. Due to the relatively small rudder, the prop effect is not that big and moving this big buy in small quarters can be a challenge. Especially when most marinas or docks where we might go are not built to receive a little bumb or pull from a 700+ ton ship.
We looked at several options so here’ the most complete list of links to professional bow/stern thrusters on the Internet 
. We saw the exciting van Velden EPS thrusters, the Brunvoll line of ‘silent’ thruster (very interesting reading by the way), Verhaar Omega thrusters and Schottel (nice stuff) but in the end we decided with our pocketbook and get a used Pleuger tunnel thruster (by Promac), 150 HP model. Since we keep our 375 HP generator, we can run both bow and stern thrusters at the same time.

But in the end we decided to keep it simple – and affordable and go with this used bow truster.

Hey, great blog it makes an interesting read!
I was looking to see if anyone has done any trawler conversions as this could well be my dissertation
Good luck with the rest of the project
