It is with great interest that I've seen greenland style rolling. I have done many of the various rolling excersizes like forward ending and backwards ending rolling. All my rolling can still be improved by repetition to become even more effortless. To me the two key elements to butterfly, balance brace, shotgun roll, forward bracing, tradional backwards sweep roll etc. has been a low volume boat and a greenland paddle. I realised what huge impact the boat type made as I was asked to repair a leaking Tahe Greenlander some years ago. It felt like cheating compared to rolling with other sea kayaks. The very low volume made it easy to stay torso afloat while seated in the boat. A fairly high volume paddle helped towards experimenting on the balance brace too.

I am at the stage where a balance brace in my self built Fragrance wood strip kayak is a routine with any paddle. But I am still missing all the handrolls. I don't think they are far away. Perhaps if I had regular access to a swiming pool then.... but I've learnt all my rolling on the open water during summertime. A neprene tuilik has also helped - giving me more water time without getting cold. But still a barrier exists - no hand roll.
Perhaps Fragrance is not low enough, or the cockpit too narrow?
Skin on Frame? To perfect my knowledge and skills of kayaking I decided to build a tradional style kayak. Using the Christopher Cunningham book for referece It took me about three weeks to finnish my first frame, choose the fabric and "skin" the frame. What came out was a nice looking boat. Slightly more tippy than wished for, and with more volume. About 10 cm of freeboard is not bad at all, but it is too much for a so called rolling machine. Chines should have been more apart and the ribs bent more sharply. On bending there is a limit for the wood. Skill is needed to choose the wood, prepare and steam it right. The size of this, my first skin on frame kayak is based on hip width, finger measures, arm spans and fist measures.
Florecent white is an impressive fabric colour. Light adds to the impression, such a contrast to the rest of the fiberglass and plastic boats at Hanko Sea Kayak Gathering last weekend (16.-18.8.2013). I hope others were inspired to build one themselves. Most of my three weeks of calendar building time was spent reading and understanding Christophers building instructions, and finding the proper way to use the tools, and sizing for masik, pegs and mortizes.
To make the kayak more durable I will add some coating to it that will likely take away some of the florecence in the colour. In addition to ultimately withstand ice it should have no problem with abrasion and sharp objects. The coating will also protect all the 160 Gathering signitures that participants were kind to share on the skin.
