I have heard some say that water shoots up through the scupper holes but that has not been my experience. Some water comes in but then goes right back out. I can see where a rudder would be great for boat control while drifting but it is really not needed. I recommend a 240cm high angle paddle especially with the seat in the high position. There are two buckles that hold the Center Hatch down. I recommend leaving the farthest one unbuckled on the water because its hard to reach when you need to access its contents.
What could make this boat better would be:
1) "Aim" the rod holders 90 degrees out instead of straight back. This separates the lines for trolling purposes.
2) Put some scupper holes in the rear deck. Not for drainage but so you can mount some wheels under it easily.
3) Make it lighter. At 74 lbs it's a beast to load and port
4) Add a break away stringer mount. So when you wish to keep fish on a stringer a shark, gator, or large grouper wont drag your boat under.
5) Finally add a Slide Trax mounting system. This is one place Jackson Kayak was sleeping.
About my Odyssey 15T: This boat is six years old, Royalex, tandem setup. What I love about this boat is it is light and easy to get on and off the water all by myself. When I get home from work I can toss it on the car at a whim and be fishing in 30min. It has very good secondary stability which scares newbies but gives me confidence in sketchy situations. It has never flipped (honestly). It has enough room for me, my fishing gear, and liberal comforts on camping trips with the kid. On rare occasions when the wife does come along I have the tandem option which keeps her happy. This boat is very quiet for birdwatching and wildlife viewing. It excels in sloughs and mangroves hidden from the wind, stalking Redfish or Ivory Bill Woodpeckers. The nylon weave seats are very durable and comfortable facing either direction.
At $900 new this boat was a good buy. This boat is not fast! In flat water I average 2.8 mph. It tracks a little on the poor side so you spend a lot of time correcting course. A J-Stroke just isn't enough, you will have to crossover if you want to go any distance fast. It also has some flex in the hull that absorbs the energy of your stroke rather than pushing your boat forward.
This boat is "tippy" to the inexperienced paddler. A friend of mine got out of her Old Town Discovery 169 and was scared to death at the lack of primary stability in the Odyssey 15T. My biggest complaint is that, after six years, the outer layer of Royalex cracked. I have decided to live with it. It does not track as straight as a 17' speed demon, nor does it have the stability of a fat 14' sportster. If you have a low budget and want one boat that does a good job at everything then this is good choice. I have not regretted my purchase.
