The reason you don't see as many prop drives on the water as Hobie's is that there are not that many around yet. I see more and more all the time out on the ocean. As far as wrapping line around the prop, pay attention. I have done it once on freshwater while trolling two rods. Rod number 1 had a fish and I stopped pedaling in the wind and I got wrapped on number two. I have put well over 1000 miles on my boat with very few weeds or kelp moments. The only place I prefer to paddle is certain areas on  the delta that are nothing but weeds, but even Hobie's have some issues in those spots. I don't ever fish in the kelp, if there was any, so that is a non issue for me. I like my Wildy Radar a LOT. The best thing you can do is try boats out for extended periods and see for yourself. If you ever want to try out a the Radar let me know. I am not too far from where you are. The Radar 135 has a ton of room on it. Close to the same room as a PA12 I would say. Tons more room than an Outback or Revo. Yes I am associated with Wilderness. I still recommend try before you buy for sure. What works for you or anyone else may not work for me. As far as stability goes, https://www.facebook.com/rob.knoles.5/videos/1944127122295682/ , I did this for 3 hours straight at Shelter Cove in the high seat position with zero issues. At Albion this year I caught 10 Salmon in slop like in the video all on the troll with zero issues too.
