helms seat on venture 23

Swivel is easy. Look in the seats section of any marine retailers' catalog or web site and you'll find swivel bases. Rases the seat about 3/4".

As far as foling- the newer seats don't seem to fold flat like they did years ago. I think seatsd are plusher and thicker, so a full fold down to flat isn't available.
 
I am in the middle of this on my CD25. I wanted to sit higher (I'm a short guy) for better visibility and also be able to swivel as you mentioned.

I am changing/adding 3 things:

1) Adding a Teleflex HA5419 20deg (recessed) wheel mount. To allow more room underneath wheel. [http://www.ebay.com/itm/TELEFLEX-HA5419-SEA-STAR-HYDRAULIC-STEERING-HELM-WEDGE-8655-/251059915636] This is complete and works well.

2) Adding a sliding/swivel mount for helm seat. [http://www.garelick.com/Low-Profile-Seat-Slide-And-Locking-Swivel] Not installed yet, but looks like it will work well. The slide function will allow the seat to move forward some to allow the swivel to occur without hitting the raised countertop behind. The additional height that it provides appears to be just perfect for me.

3) Adding a new helm seat that is a bit narrower and not so "corner-y" in the back corners to allow easier swiveling and clearance. [http://www.cabelas.com/catalog/product_read_only.jsp?productId=935435] Not installed yet.

I'll post photos when the project is complete (I am doing about 1000 other ones at the same time!!!)
 
One of the Attwood .pdf docs for these Centric II seats lists a suspension option:

"The SAS suspension is an option for the more advanced applications, where maximum comfort and support is desired".

Their drawings are pretty cryptic, but it appears that the seat cushion sits over tensioned cables, each individually connecting to a spring.

I'm familiar with other marine/truck seat suspension systems, and this one seems to be pretty minimalist, and totally concealed withing the seat itself.

Some seat suspension systems are larger than the seat itself, and have a combo of springs and hydraulic shock absorbers, with multiple adjustments, so I'm not expecting a lot from Attwood's solution.

Attwood is impressive in that virtually every component of their seats is available as a repair part, something totally lacking with many other marine seat brands...could make the difference between fixing and replacing sometime down the road.

Any experience with these?
 
I was excited when this topic started. I would like to be raised a little and having a fore/ aft slide would be great. Having been by the boat today I have to ask how one reaches he bolts he hold he existing seat. Do. Have to remove he fridge ?

Thanks
 
Sorry, I somehow thought you had used the Centric II seats. I don't think the plain Centrics have the suspension option.

Also, with the seat back folded down, does that provide a flat, level surface that could nicely accommodate a cutting board or something similar that could temporarily expand the galley work surfaces, or, is it somewhat angled
and/or too rounded to do that?
 
There's not much flat surface there as you can see in the "folded" photo. If you really had to have it, you'd have to come up with something that sat over the top of the folded seat that had a good amount of surface area.

Click to expand...

I'm already thinking big cutting board, attached to beanbag...

I think Attwood is missing an opportunity here, unless the Centric II has already improved the situation.

Small boats need lots of versatility to become space-efficient...every square-inch and every cubic-inch needs to count, and be multi-functional.

The footprint of a folding seat represents a significant amount potentially-wasted inches.

Although I acquired this concept from boats, I'm currently applying it to small houses, too, one of which I'm in the process of determining "how small can you go?"
 
I think that 99% of these seats are installed in boats where having a flat folder seatback isn't an advantage. There are still models that do fold flat, but they have gotten fewer.

I like fold flat models on open boats as it allows the captain to sit higher at times by sitting on the folded seatback.
