I will tell you YOU WILL NOT WANT YOUR IPHONE/IPAD/I WHATEVER laying on the helm anyhow. Mine gets VERY HOT !!!!!
I keep it under my cigar pack, and it still gets warm.
If you do want it up there, get some of that dash pad sticky for phones, and cut it to fit the 2 recesses on top and also drill a couple small drain holes and run tubing from them down to the hole in deck to drain. Also, I think an ipad mounts not feasible, it's too big, now an ipad mini .... Yeah, that would be cool. I think a mini would fit to the right of the steering wheel. Just get a universal mini car mount and mount that to helm.....
Access doors can be held with the little stops they use on others, but I was told they are toe stub bears, so that may be why all doors don't have them. I'm thinking I may put a strap with snaps on my bow door with a snap on my kick panel under seat edge, so I can hold it open.
