Author Topic:   Size of Stern Seat
kamie posted 03-17-2004 04:33 PM ET (US)   Profile for kamie   Send Email to kamie  
I am trying to decide on adding the stern seat to the 18' I have. Before I spend $850 - $1700 I was hoping to figure out once and for all if it is really worth it to add the seat. Does anyone know the depth of the seat front to back and the height from the deck to the bottom of the seat. Trying to work out 3 things.

1. Total deck space I will loose by adding the seat.
2, How ususable the space under the seat will be for storage.
3. Where the seat will endup in relation to my current captains chairs or the new RPS.

I know from earlier discussions that folks that have the seat like them and find them comfy, especially the women of the family. I am really trying to see if the seat will make an already crowded 18' to crowded.

Thanks for any help

Unless someone gets to it today, I'll get all those dimensions to you tomorrow.
It'll give me a chance to go in the warehouse and stare at my Outrage.

Take your time staring at the boat. I am planning the same sort of trip to the marina this weekend.

I have a 1997 21 Outrage and it has the Whaler rear seat option. It is very comfortable and the kids and the girlfriend really like it for cruising around. The seat is the full width of the cockpit (it has to be close to 5-6 feet wide) mounted to the floor. For me it makes it difficult to get to the stern lines without standing on the seat. My oil tank is in the rear well behind it under a hatch- with the seat there it is difficult to access the hatch to fill the tank. I fish alot so I do not like the seat there while fishing. The seat is removable by unscrewing four knobs and simply lifting the seat out of the boat but it is very heavy and it is too large to store on the dock while I am out. Also, when I tilt the motor all the way up it does hit the seat a bit. I like to peek back at the motor while running to check water flow and trim and it makes it difficult to see the motor. I really like the seat for passenger comfort but otherwise it does get in my way.

Birdsall Marine design makes a folding rear bench and backrest in various sizes.(
If I can figure out a way to mount it I think I will go with that setup. I just ordered a leaning post from them and they were a pleasure to deal with- I haven't received it yet (supposed to ship today!) but I have heard the quality is excellent.

Thanks for the info. I can see where the seat would get in the way of the external oil tanks although if your engine hits the seat when tilted, the seat may be too far back. In the install drawing from Mike it says a minimum of 29" from the stern to allow for engine tilt. Ultimatly when I replace the current engine, my plan is to put the new engine(s) on setback brackets to clear the splashwell. The other hope is that I will be replacing the engine with one that has an internal oil tank so the external tank can go away as well.

Stern seats are one of personality and need. If you want one for comfort then they come in designs that make you deal with form and function.

Why anyone would charge you so much for a stern seat, is ridiculous. There has got to be some type of Marine Manufactruer in your area.. especially with all of the independent Naval Shipyards that dole out independent contracts.

I paid $800 for a teak dive seat, that folds down, and is removable for my boat... it used to be fit in my 1980 V-20 Outrage but then had it modified to fit into my new (still being repowered) 1994 BW Outrage 24.

Yes, because it was modified, I had no problems clearing all of the deck plate access hatches.

I'm down in Miami, where a lot of boats are made, so I went to Marine Manufacturing with my boat. I had them make the clearance high enough so that I could put a couple of Igloo Coolers under it, a port-a-potty, and a 5 gal reserve fuel tank. I still had room for my Fenders and some rope.

Before you go stock, and buy a stern seat from anyone, try your local marine fabricator in the Yellow Pages.

Good Luck,

I think putting a jack plate with 12" setback would make a lot of sense if you are concerned about opening up interior room when putting in a stern seat. This way, you could push the seat back farther in the boat without interfering with the ability to tilt the motor.

I agree up to a point. If you try to push it back to far then you have to straddle the transom bulkhead.
This would leave you no room to put anything underneath.
Also I don't know if the bar across the back of the seat would still hit the side of the gunwales, or would be to far back.
I put mine back farther so that the back of the legs was right in front of the seam for the gas tank deck cover.
I just tilted up the motor and gave it a couple of inches for room and figured out where it would have to go.
Those diagrams I sent you are for a 20' & 22'. I'm assuming there would be no difference between those and the 18' Outrage.

I would have to agree with BEACHPANDA also, I would think you would be able to find one in decent shape for less than that.

I bought mine used for $350.00 last summer. Granted, it's not in the best shape but it's comfortable and no one else can tell the difference.

I agree, but it depends on the boat. I have a 22 with the older splash well design, so the dam is much less limiting than it would be on the newer design.

On Kamie's 18 (and yours), it is obviously an issue - one I hadn't thought about.

David, have you considered making a seat? I have been nothing but happy with the added utility value my stern seat brought me. Sounds like I have about the same hull as you do... pete

Beachpanda, I farther north than most of the Navy contracts involving real ships. Those are mostly down in the Norfolk area, the ones near me involve just a lot of paper and not much else. Not the concentration of folks in my area like there are in Miami. I am not adversed to having one built if I need too to make it more useful if I can find someone to do the job. What I am first trying to figure out is, is it realistic to put one in an 18' Outrage. It seems that most folks that have one have 20' or larger which makes a lot of sense. Assuming the splashwell being the same size, the 20 is a foot longer than the 18 and that foot is pure deck space.

Mike, I agree that I can probably find a used one and if I decide that the seat is a good idea I will keep my eyes open for one. $850 is for a new seat from Art's. The issue seems to be that not a lot went into 18 Outrages, probably because of the space you lost. More likely to be put into a 20 or larger for crusing. Not to say they aren't out there, just what I have noticed.

David, On an 18 foot boat with limited storage you have to do something. Opening up the splashwell by moving the engine farther aft just makes sense, seat or no seat. For me any gains in performance would be secondary to the added storage.

I've still got the pictures you sent me filed away... I love the way yours is removable or can be reversed.

My tablesaw and joiner are still in storage - It will be spring before they come out and I can get started.

Kamie, I have the stern seat in our 1992 Outrage 19. It runs gunwale to gunwale and mounts with two bolts in each of the four legs. It's easy to remove/install but a bit hard to store so we leave it in the boat. There is enough room to walk around the RPS and the extra seating makes things more comfortable with the family ( girls 4 and 6 ) The boat is still in storage at my brother in laws, god bless him, so I don't have any exact dimensions. I made a cargo net out of 1" nylon stapping and quick release plastic buckles and store two spare life jackets under the seat. We do inland fresh water stuff, ski/tube, and climb right over it without problem including the non-athletic and the pregnant. Joe

Thanks Joe, Mike sent me the measurements of the seat so I made a carboard mockup.. Going to the boat today to get her ready and going to drop the cutout in the back and try to walk around it. I will probably try to find a used one around that fits and 18' Outrage. How easy would yours be to climb over if it was about 2" higher. Would love to slide a porta-potty under it.

It has been a looong winter and I have not touched the boat since it went in lockdown last October. Still, I can't see 2" being that big of a deal. How much stuff is in your splashwell? We have the VRO tank and a small portable fuel tank for the kicker so it is starting to get a little crowded. If you can keep a good footing around your gear, go for it. Joe

Thanks Joe, I think i'll keep my eyes open for a used one. It's little tight with the current captins chairs but i'm sure things would work out fine, especially if I replace them with the RPS. The only thing in my splashwell is the battery and the oil tanks.

I am trying to confirm the exact measurements for the OEM stern seat for the 18' Outrage. Through my discussions with Kamie, I have learned the following:

Seat depth: 19 1/2"
Seat Height from the lip to the deck: 10 1/4"
Seat Length/Width: Approximately 68"
Backrest Height: ?

Can anyone confirm these measurements for the 18' stern seat and also provide me with the backrest height.

I am looking to confirm if it would be cheaper to have a local upholsterer manufacture the seat or purchase the same from Art's in Brockton for approx. $850.

Thanks in advance.
