Seems lIke this boat has he most twin screw applications of any de boat out there. Anyone have any first hand experience with a twin screw Duffy? Or any twin screw de? I always kinda figured they were a nightmare to run but I never ran one. It's raining and windy on my only day off this week so I got nothing better to do with my time!

Capt. Mark in Montauk is a twin screw. I think it's a BHM. I've been on the boat before and it seemed ok. I always heard to stay away from twin screw downeasts, but Mark's boat is a beast!!

El mar, she's all clean and ready to go.

I was trolling through yachtworld earlier and saw a few on there, the zora looks like a nice boat but I think it would probably sell for 50k more and fast if it had a single.

There is a 42' w/ two engines in Hatteras. He's on this board; not sure how often he checks it.

That's her. Looks like a nice rig

I wish I had some info on it for you but it's pretty much a mystery. First boat on its morning and last to leave but it never goes any where. It's rigged out with a green stick, tower, and seems to be very seriously tuna rigged but it is never used. I honestly thought the first year George's took off it may move, maybe they were waiting for a real good bite for the last years, but that ever happened either.

I'm more curious then interested, if the boat ran good with twins it has great power.

42 Duffy
My 42 Duffy is a twin screw boat. I do not know how many of the 42 Duffys are, but it is probably just a few. I saw two with twins when I was shopping and the other had a pair of John Deeres but was too much of a yacht for my needs.

The boat runs just great with two 375hp 3208s in it and cruises 17 to 18 loaded with ten divers all their gear and half full tanks. Handles very well and super easy to dock. The keel is bobbed off and blended back up into the hull but still protects all the gear when you bump the shoal (yes I have tested that feature - just once so far). It will run on just one fairly well to hull speed and it will even turn into the good engine side.

I was not keen on a twin DE boat when I was shopping for one, but do like having the redundant power to get home if needed. Downside is the additional maintenance plus it does limit the repower options as the engines are placed outboard of that deep keel area where a lot of big singles could fit so well. Upside is that you rarely have anything that will take out both engines and in other boats I have limped home on one many times over the years. I have had some of the customers say they like the fact that there are two engines on the boat, but what do they really know about it and most don't have a clue about what moves the boat along. If I was having one built new, I might have to consider having a twin again if the cost was not too over the top.

There is an extensive listing on the Duffy site of this boat.

to be honest, and this is hard for me to admit since I think the boat is rigged out balls-to-the-wall, it might not get used that much because it might be a carnival ride in any sort of beam sea. With that tall, heavy tower and the shaved keel to accomodate the additional speed of the twin screws, I bet she'll rock you to death on the drift/hook/even trolling.

I think the twin screw idea might be better served in a Wesmac type of hull, more of a hybrid. There is a big 46' with a blue hull that I think is down New Bedford way that has a pair of QSMs in it. Big tall tower too, I wonder how that beast runs, and if/how much the keel was shaved?
