I am 6' 210lbs, bought the 165 as a pack mule for longer trips. With nearly 100lbs of cargo aboard this boat is stable and tracks beautifully, is very responsive to edging, I did not roll it fully loaded but I believe it is very do-able. I have been out in 4' swells and 30plus mph winds and it takes things very easily without a lot of fuss. A good skirt is essential as water will broach when waves come from the sides or rear, waves head on are cleanly sliced.
Empty the boat can be a handful, it weathercocks when winds are quartering from the rear pretty badly, but can be corrected with edging and sweeps. Quartering waves from the rear require sweeps and braces to correct the course. If you have plans on using the boat empty I would suggest the rudder option that is available.
The boat is about average speed for a boat of this length, glide is not great. With a little practice surfing is good but again breaking waves will wash up and attempt to clear the deck.
Seats and outfitting are typical of WS boats, good and functional. This is a boat I will keep, it is a work horse.
I give this boat the rating 8 of 10 due to weight.Purchased Tsunami 165 for its carrying capacity as a pack mule on trips. I loaded it up for a test trip on the worst day possible, 30 mph winds on a busy lake the weekend before the 4th of July (loaded with power boats). The boat did not disappoint me.
I did not order a rudder, and the boat tracked like it was on rails, edging and paddling pointed it with very little effort. I un-balasted the boat with just me (210lbs) and went out again, still very little wind cocking in this high volume boat. Overall very controllable.
It does not turn on a dime but is pretty nimble for a mid length boat. Its speed was pretty average for a boat of this length, with a decent glide. I decided to throw caution to the winds and see if I could self rescue and did a wet exit, I was able to easily do a cowboy rescue (due to the large hatch), it is a wide boat, and very stable, I did not attempt a roll as I was without a skirt.
The back band style seat may not suit some people as you cannot rely on it to rest back on during a restful paddle, you do have to maintain your own posture, but it does allow full rotation and movement and is very adjustable for comfort.
Not a boat for a 3 hour trip, but a good boat for an 8 hour trip with a lot of stuff.
