Default 50' Spencer with Jet Drives

Just ran across this article and haven't been able to find much about it:

https://www.marlinmag.com/spencer-yachts-50-preview

Has anyone heard about this or of any new builds going this route? I love seeing the big Hinckley's back right up the beach - it would be equally impressive to see a large sportfish do it as well. I am curious if this "new technology" can generate an effective fishing platform instead of just being known for cruising.

Thoughts?

Updated with pictures (thanks coores for FB reference):

Their next delivery to Tahiti will be a success.

it's finished and is putting up some impressive numbers. It was my understanding always that jet drives were inherently less efficient than props, but when I questioned Spencer about it they said they're getting much better speed and efficiency than with props. Said they saw a 10 knot increase over props. And a 26" draft.
Times have changed I guess.

so far they've seen 70gph at 40 knots and 95gph at 50 knots.
That's pretty crazy.

Thanks for the update! A fifty footer with a 26in draft is crazy.. the versatility would be a game changer for sure if the fishability is still there.

the only fishability issue I could imagine would be the turbulence/noise of the jet drives.
Otherwise, the maneuverability might even be better than with props mainly because you don't have a traditional transmission to worry about when shifting in and out of gear. And if they could create something like the Hinckley JetStick then it would undoubtedly be more maneuverable.
The Hinckley I run with jet drives is pretty amazing with what you can do with it when using their JetStick.

That's unreal. Shit the boat I used to mate on burned 100gph at 28 knot cruise.

I wonder how much white water there is at trolling speed

I was concerned about what mako said above with white water at trolling speed, along with bringing fish to the back of the boat.

yeah I wasn't thinking about the drives sticking out the back. Definitely would be an issue.

Maintenance wise, cheaper than traditional running gear too?

here's a shot of the rear.



I've gotta imagine that they're cheaper than traditional running gear. One big ass Nibral prop ain't cheap. Surely an impeller would be less, I'd hope.

Pretty sure when you're on a 50' Spencer, the blue marlin jump into the boat willingly.

Fishing weed lines might be a problem as well.

no idea what the name of the color is, but it's a dark grey of sorts.

If you go on the Spencer Yachts facebook page they have tons of pics and running videos of it. From the looks of things, the jet drives don't appear to stick out like the Hamilton drives. And the wake, at least at cruise looks great.

I believe the 26" draft is the main reason they went with jets for this build. The owner is somewhere up north in a lake, and had concerns about water depth. It is not a fishing boat either.

that's correct. The boat just finished its journey up there. Some cool pics of it passing the Statue of Liberty and what not.

Sorry, but a Spencer that lives on a lake just doesn't seem right to me.

That's a nice rocket launcher for decoration!

May not be a dedicated fishing boat but I think it looks great.
