Carver 355 Swim Platform; info request

I have just acquired a Carver 355 1998, however it is closed up for the winter as are all the boats in this area. Perhaps an owner in a more southern climate can get me some of this information.

I need measurements of the swim platform.

Front to back, (the depth), side to side , from the right side edge of the spiral STAIRCASE , all the way to starboard inside edge.

On the swim platform, in the case of those of you with boats that have the storage dockbox on board, what is the height of the top of the box, and at what height is the top of the window. Also , how far is it set back from the edge of the platform

I am giving up using the flip up style davits as I do not want to continuously remove my now heavier engine on a soft bottom dinghy, so I am looking to put on Hurley Davits, which maintains the boat in a flat position , ready to go, with everything in it.

In addition to this, I have a SURFJET, a motorized surfboard, which I would like to put either on the deck in place of the deckbox, or on a cradle resting just above the aft window , immediately to the right of the stairs. I will assemble a hoist for lifting this.

Also, just above the emblem to the right of the handrail, what is the height of the opening to the rear upperdeck below the plastic in the photo. I will need access to stanchions for securing my items.
Thanks to anyone who may be able to assist me. It is about to be a long winter.

I have attached photos to help illustrate my intentions.

i really appreciate this information. I am also happy to hear that you still have use of your platform.many people had suggest an expensive Laconner marine hydraulic unit, however , just looking at the pictures I can see that this is the end of use of the swimplatform for anything useful..
It must be a real treat having the engine permanently mounted and ready to go.
Thank you for responding.
I still must contact somebody with a 355 to get some measurements so that I can get started and order the Hurley, as per their order diagram requirements.
thank you again.

Thank you for your reply , which I appreciate. I notice you are using the weaver lever. What size engine is it supporting. I also notice that you also have an engine mount bracket on the right side of your transom. Do you ever use that. At what point would you bother to lift of your engine.
One last point worth mentioning. At this point I do not have an RIB, I still have a soft bottom. I always felt that hanging a larger motor , (upright) and putting all the weight on the lower pontoon with no rigid bottom, would spoil the dinghy.

Thanks.
PS
i still could use some rough measurements , at least the distance from the stairs (rail) to the right inside edge

thank you very much for taking the time to answer.Based on this info of 85.5 I know that my board will fit into this area.
I wanted you to know that I did contact Carver Yachts and there was no way that they could help me. for a 1998! I also reviewed the pictures of the actual boat I have purchased and realize that my deck box is not the full width, which means i have space on its right hand side.. Do you have any idea how the motor mount would have been attached, (back plates etc) or if it is strong. I may use it as lateral support for the mini crane that I wish to install.
Again, thank you for your time and measurements. I will not get to my boat until mid April.

It might look like too many toys,but this boat is now bigger than my 30, and the jet is only 120 lbs ,so overall in weight its like havinga kid at the back. See the photo of what and how i lived on the 30',a dinghy up at the back against the jet across the top of the taff rail, blocking my seat. I suppose if i went to the trouble of having the upper deck crane, i could put it on the roof, but then i would hesitate more often from using it or putting it away .
I am currently using 9.5 dinghy with an 8 2 stroke, and wanted more power for guest pick ups at marinas so I was hoping to go with a 15 but was worried about installing this on the shorter dinghy.( recommended max is 10hp)
So many decisions and no access until april. Additionally , i thought of using the Hurley davits which would keep the boat flat.
Thank you for taking the time to answer. It was interesting to me that you are able to put a 15 on a soft bottom, and then lift it with the engine on, into the vertical position.
By locking in the down position, your engine sticks out as well. Is it a 4 stroke?
