Due to the continued lack of feedback on the R21, I will add my experience so far, brief as it is.
I have done several paddles in my full carbon R21 now, and have to say I have been pleasantly surprised, mainly with the great stability for such a narrow boat ( for me ).
I paddled SLSC spec skis in my 20's, moved on to K1's and recreational flat water in my 30's, and now at a bit too tubby 42, I decided to finally get that long pondered ocean racer. I have followed the information here for some time, and had planned to go the typical Think or Epic route, when by chance I dropped into Ozflyte on the Sunshine Coast for a lookie see, having no idea at the time they had ventured into ocean racers.
I have not paddled since the GFC in 2008, when I lost my job and had to sell my toys towards the end of the year to get by. Thus my extra lard, and a distinct lack of paddle fitness/ balance stabilizers!!
My first paddle was in a dead flat freshwater lake, and I dressed for a swim, fully expecting to go through the same learning curve as I did with the K1. I would rate my K1 stability as OK on flat water, but I did struggle without a blade in the water. In a more choppy environment, such as the Brisbane River, a k1 klever was the limit of my balance ability, and after swamping it trying to play with the bow wave of a large boat, I decided to stick to the lakes.
I set off on the R21, and was initially surprised by the feeling of being on a K1 like V hull, yet a bit of an exploratory wiggle revealed an apparent secondary stability. Given the fact my arms were starting to complain about actually having to do something, I decided against more vigorous balance experiments, and continued on to complete a soul fulfilling yet short paddle, and not once did I get that dreaded " going over" feeling. The R21 is a fast boat, doesn't feel quite K1 fast, but given my lack of fitness, I figure it was me holding the boat back, not the other way around! That first paddle was even with my legs set up too short, so that only adds to the fact the boat is quite stable in flat water. I also noticed there was almost no bow wave, and less wake than a klever, guess a longer shape provides that, but I was surprised all the same.
My next few paddles have been in the Brisbane River, and whilst this is well short of ocean chop, is still my next level of testing given my K1 experiences. Again that stability is there, to the point where I just take the Rivercat and boat wakes side on now, and I am only two weeks in. I would rate the R21 as very spec ski like in stability, although its been a loooong time since I have paddled one properly, but it is definitely more TK1 like stability wise, over my former klevers.
Turning circle is terrible, but given this is the longest boat I have yet had, I expected that, and I am more interested in distance paddling anyway. The rudder is responsive for small course corrections, and I guess once I feel I have some fitness built up and brave the surf, I can comment further in it's intended environment.
As a current size 36 arse (should be 34 ) the seat is comfortable, but I am touching the sides. I would think bigger blokes may have trouble with good hip rotation. It feels as narrow as a K1, certainly if one of the many bull sharks in the river decided to have a go, there's stuff all boat at the sides between me and them.
My only real complaint is the footwell holds water at a bit below water level, depending on how hard I paddle, but as this is a used boat, I expect the skipper flaps need a bit of work. The footwell isnt deep, so this is only a small amount of water, less than a litre, but I am keen to fix that. Finish of the ski is superb, even in used state, and the only problem I had to fix were the front anchor points of the rudder cables. The alloy rivets had corroded through, and both anchor points were barely hanging on, nothing some stainless screws and liquid steel couldn't fix.
I will report back once I have had a crack in some surf, but that won't be until I get some fitness and my flexibility back, and my feet stop going to sleep 30 mins in! The thin seat pad is minimal yet comfortable, and having never paddled with one, it hardly feels like it is there, but it does give that wax like grip without the mess. I like it.
So I would rate the R21 as a great ski for anyone looking to move up to an ocean racer, and even say it would be OK for a beginner on flat water with a bit of swimming. Certainly an easy transition from a spec ski, which the R21 is obviously based around.
Can't wait to go for another paddle!
