I dive in similar water in Puget Sound / BC and also use dry gloves.
I'm using an Ikelite housing, dual DS-125 strobes, Canon G9, fisheye 48 LED focus light, ULCS 5 & 8 inch arms. System was right around $3000. Advanced point and shoot, with manual controls, and some room to grow creatively. It has a limited f-stop range compared to an SLR but the package was significantly cheaper than the Nikon I was considering -- and it still does great pictures.
If you You may want to read the reviews on Wetpixel of the Stix bouyancy arms or consider floatation arms by ULCS etc. I've added the floats to my arms and the system is still negative.
The controls are large enough to be able to use most of them easily with gloves. On the camera and housing there is a spot where there are 5 buttons in close proximity that are a little difficult, but manageable. Ikelite also makes a short port for the Inon WA lens.
One key for the strobes in water with lots of particulates, like we have, is to get the strobes out away from the camera around a 45 degree angle. This will greatly reduce the backscatter you'll get. My strobe arms are 15 inches with the clamps and I'm still thinking of changing my 5 inch for an 8. I wouldn't need that tropical or clear, but when it gets murky. . . .
The G9 also does have a stitch mode where you can tie a series of pictures together by overlapping the edge of the last picture. This was set up for panorama shots so it should work Ok, but I'm not certain how easy it is to use UW in a housing. Works in my living room.
Finally, if you're thinking of really taking wide angle shots of a ship the strobe won't do you much good. Too little light, too much surface area. You might consider natural light and stitch mode. That may save you some money on strobes as well.
Good luck.
