Calling all Mariner 360 Owners
Would like to create a new thread just for this model.
We've had a 2004 Mariner 360 for about a year now and like it for the most part. The crusader 6.0s seem great, love how it's almost all FWC. I've learned a lot about this boat over the past year so I am sure I can offer advice to any new or existing owners.
General question, though, do all these models sit bow heavy? Has anyone figured out why? We can't even completely empty our holding tank because it sits on a slight angle.
And has anyone figured out why when in heavy seas, so much water collects in the forward bilge? The forward bilge hose does have a loop so I am not sure why it would siphon there and if it's not there, from where? And if somewhere on the aft bilges, would that also suggest the potable tank might be taking on sea water through the overflow?
Thanks!

Re: Calling all Mariner 360 Owners
How much anchor chain do you run? Lots of that will cause a lot of boats to be bow heavy.
In heavy seas, can water get in your anchor locker through the winch or any storage doors in the bow?
You should definitely not have an issue with seas getting in the potable "overflow" (it's actually a vent). The vent should be located a few feet above the water line and have a loop in it that would go even further up. I would be concerned about contaminating the potable water if sea water was actually getting in there.

Re: Calling all Mariner 360 Owners
Thanks for the reply! 150 feet of chain with 35lb anchor. I was wondering that too but its what Carver delivered with this model...but given some of questionable design decisions, maybe they didn't account for the weight? But 150 feet doesn't seem excessive.
The actor locker is accessed through the forward stateroom but actually drains out the bow and not to the bilge.

Re: Calling all Mariner 360 Owners
I When we were looking for a boat we were looking for a mariner And every new style mariner from 98 up all had a slight down downhill towards the bow.
We always wondered why that was
We ended up buying a 95 older style

Re: Calling all Mariner 360 Owners
I don't think the boat is bow heavy....it is the deck design that makes it appear that way.......could also be how you run the boat.....on plane it is not bow down at all. There has been issues with these boats picking up water backflow into the forward bilge thru hoses and the upper deck drainage around and under the bridge front coaming.
This will be especially evident if you run the boat between hull speed ( 7Kn) and on plane around (15Kn).
My opinion anyway.

FWIW.....The above is just my opinion.

Re: Calling all Mariner 360 Owners
Different question on the 360 Mariner. We are new owners of a 2006 360 Mariner and need tips for the best settings for the Vimar heater control panels. The fan runs continuously after reaching set point even when set to Auto. Is that typical?
We have been Carver owners for over 20 years, previously had a Santego.
Thank you…

Re: Calling all Mariner 360 Owners
Hi, Cbchristian2, I don’t recall what brand our climate control panels are, but ya, the fan runs continuously even after reaching set point… it’s annoying. If you have any other questions, let me know… after owning this boat for a year, I’ve become intimately familiar with it… (engine wise, we have crusader 6.0s)

I've only had water in the FWD bilge when the Shower sump failed and filled with water.

Re: Calling all Mariner 360 Owners
Hello all,
I know this is an old thread, but it may get me right to a couple 360 Mariner owners. Recently purchased a 2004 Mariner 360. Have purchased a chartplotter with a transducer that I would like place on the stern on the keel or as close as I can get. I have only seen this boat in the water - never out. Does anyone know how far below the waterline the keel is at the stern?
I'd like to use a piece of UHMW/StarBoard for mounting the transducer at the bottom of the boat. I would mount the UHMW to the stern with screws penetrating the boat's shell above the waterline. The UHMW would then extend from that point down to the keel and provide me with a mounting point for the transducer.
Thanks!
P.S. I have read the maximum draft is right around 3.1 feet, but that is forward of the stern. Stern sits higher I believe.

Re: Calling all Mariner 360 Owners
Does that boat have a keel? I perused a couple pics online, and it doesn't look like it does. But if it does and you place the transducer at the stern behind the keel, then you may get turbulence that would affect performance.
In some pics it also looks like there's a drain plug located on the transom centerline, just inches above the bottom. That might complicate centering the starboard support.
It also appears in some of the pics that there's a "stepped transom" where some of the transom is right at the back of the swim platform and then it steps forward a couple feet before it continues down to the bottom of the hull.
You also want to make sure you're well clear of any turbulence from the props and rudders, or you'll never get a reliable signal underway.
And of that 3' draft, a substantial portion of that is the props or rudders, and their clearance to the hull. I'd bet the center of the hull is less than 12-14" below the waterline.
