I can see why a stern thruster would be much easier in your situation. Whereas splitting the gears works, you have finer control and can feather a thruster much better than just using the wheels. At least that’s been my experience.
I agree, but in my case it's really about holding station in a lock or holding the boat to the dock while securing.
I'm having this put on my 53'. https://www.seatechmarineproducts.c...rop-dc-thruster-on-off-for-boats-50-70ft.html I call the FL Bow thruster guy and the quote I got was of the; "I don't want your business" amount. So, I'm having a local shop install it at the marina. They have installed stern thrusters before, and I saw work they've done. I will get to supervise.
I just took a gander through the jetthruster site. Would need a dual pump and four ports for boats over 50' with a fair amount of cabin height(most power yachts). Getting pretty pricey just for the materials. Labor would be higher as well. Looks like a very nice setup with the jet pump, but the cost is a bit high.
I to looked into, I couldn't get follow-up to my attempts to put a package together. I decided I didn't need to work that hard to spend money. So I found a guy that cares.
My dart board said about 20k Euros for the bits, and maybe 90-100 hours installed for the dual 90Kg. Lotta plumbing and lotta batts too. My dart board for the Side Thruster seems to be $5600 for the unit delivered to the shop, and about $7500 install, maybe a bit less if I have the bottom job done at the same time.
