Radar/sport arch - swim platform
 

Well I figured I'd start posting my add-on's here so the group could find them easier
As some of you all know I'm adding a arch and swim platform to "OFF DUTY" this off season. The topic started on another thread by Howardz302 but not wanting to hijack his post ill start here.

To recap a bit I've always liked the sport arch, radar arch look on some express cruisers and wanted to add one to this great boat for a different look.

The swim platform is another add I needed (as I walked off the back on my maidan outing last April 56 degree water after the group stopped lol we decided it was a need) but was wanting a different look then the stock one.
Swimplatform.com was the nicest looking but still was looking for a little different look. The offshore/performance boat look was the thing I keep going back to but couldn't find one to fit and the company that builds them wants the boat in there shop (in AZ.) to build one and 3k plus and not real reassuring that they could do it.

Arch: I have most of the tubing bent for it just waiting to finish up some firetrucks that are in the shop now to have room to make the jig that mocks the top rail on the hull to get the start angle right as to not work on the boat surface itself. Welding spots on or in her would not be good no matter how much you cover it happens.
The finish idea is to have a few more speakers mounted in the fiberglass and to have a top that can handle WOT speeds. Also have a place to add wakeboard style speakers if needed down the road for some more volume as we are out of the boat in the coves.

Swim platform : The platform is more complete as I didn't need as much room or extra hands to hold it. The main hoop is 26"x84" 1 1/2" round tube and the floor is 1 1/2"x1" oval tube for a smoother walking surface with the corners having 1" tube arched to make and area for 2 cup holders to be dropped in each side. Playing with clear plexiglass in the corner right now and tint the bottom to give it a smoked look.
As I was ordering material I was concerned and mindful of weight as it was a steel structure and just how much can the hull handle hanging off the back 100# was the goal and as of now I'm at 86# once I add lower braces and paint ill be really close.
The swimplatform.com one is 90#

With all that said does anybody happen to know the thickness of the transom where the platforms mount like this one from swimplatform?

great ideas

I love the forward radar arch idea. I would be curious to know how you are beefing it up to support WOT. Also, what would that run to do?

Csterner sorry it took a bit to get back to ya but was trying to get some pics so you can see how I'm thinking strong enough to handle WOT stress.
Plan is to bolt it right on that 18" flat spot behind the windshield on top and then under side will be a 2"x4"x48" channel like piece bent to match the inside curves of the hull with the 24" long side going forward to help hold the stress of wind and the remaining 6"s in the rear to help when a buddy try's to use it to hold himself up by hold down on the front. And I'm still thinking of a 60" long piece if I can get it to fit.

Cost not sure just yet this is the proto type and have a TON of time in it.
After this one is done I can cut a pattern and cut the time and cost down



Keep in mind These pics are of the main frame that will be all covered in fiberglass

looks great and I can see your project moving forward quite well.

I like everything you mentioned on the arch, I sure hope I still have dibs on the first one....
Love the updates.

They are looking good. Can't wait to see the final result.

Productive day. Arch is all tacked up and ready for a test fit. Ended up doing a 5" rake front to back to help with wind and stepping off the sun pad down to the floor. Being 6'4" hitting my head is common but hoping this will help that.
If it all fits like I measured it should be 7' off the floor at the helm.

Ill know in the morning going to get "off duty" out of hiding and try it on.

Thanks for all the replies glad to know I'm not totally jacking a great boat with a bad idea
