Good News

Clint's design the Drake Rowboat, "A new take on the Faering for the modern oarsman" is featured in the 2010 Small Boats edition by Wooden Boat Publications. It is on newstands and it is a great issue. Click here for more info.

Clint is also a recommended US builder for Michael Storer boat designer and will be producing a line of high-performance rudders and centerboards using a unique foil template developed for small boats by Michael Storer with research done by Aerodynamicist Neil Pollock. In addition to high performance foils, look for tillers, Birdsmouth masts and spars, and a new oar designed by Clint employing carbon fiber blades on a refined Sitka Spruce loom. This new oar will be up in a few days, so stay tuned! You can see more about Michael Storer's talk at my shop earlier in this blog site. Michael's website is http://www.storerboatplans.com/

Fall Row

Today was a short 9 mile row around some inner islands of Casco Bay. Pushed hard and maintained a little under 5 kts much of the time. One of the few times I've really pulled much of a wake in Drake. One thing to look for in any great rowboat is the wake. The clean exit of water such that it is not attached to the boat, but rather breaks cleanly from the surface of the boat as the hull passes by means less drag. When power is applied to a boat's hull, the stern is depressed as the hull approaches hull speed and tries to climb the bow wave created by the hull itself. The result of this is drag from the transom, if the boat has one. Others have commented about the lack of any visible wake left as we row by in Drake. The trade off of this low drag means that it is tough to hit top speeds...getting into the 5-6 knot range is something I have not done with Drake for any stretch, but have also not spent much time trying to do. This row I took, leaving the kids behind with Mom on the beach, saw a variety of conditions that reminded me how proud I am of designing Drake. Whether it was headwind, tailwind, a cross-breeze, a chop on top of open ocean swell, or bucking a strong flood tidal current, we were still able to maintain 4.5 + knots for about 2 hours. My wife, who was a top collegiate sculler, commented as I rowed back onto the beach, "Holy cow, that was quick! How'd you do that so fast."

On November 1st I was pleased and honored to introduce Michael Storer, an Australian Boat Designer reputed for his simple, elegant, and approachable boats, to a group of 21 members from the wooden boat community in Maine, Massachusetts, and New Hampshire. Some knew of Storer's work, others have built his boats, and many knew him as an important name and wanted to learn more about the man and his message. His message was simple: that we can vastly improve our boats by paying a great deal more attention to three areas: the centerboard and rudder foils, the spars and sail, and the hull itself. With regards to the foils, Michael convinced is audience that it is the way they are made -- with care towards fair, accurate foil shape and towards a smooth surface -- that most matters. Michael has taken research in optimal foil design and applied these foils to boats that, without them, would not sail nearly as well upwind and would be much trickier to handle. These foils are flat in the middle, thin for reducing weight and wood use, and closely approximate the hydrodynamics of a true NACA shape, without the expense and fuss and awkwardness of a wing-shaped foil in a square centerboard box or rocking around on a flat work bench during shaping.

With regards to spars and sails, Michael's point was clear that the most important aspect of spars is that they flex and bend in the right way, the right amount. Spar bend is critical to the ability of a sail rig to absorb a gust, reducing heeling and putting the energy into forward momentum. The sail need not be a 600-dollar racing sail, but a simple polytarp will do cut with round to create the draft necessary to create power in the sail. His PDR Oz boats are a case in point. They all sail with polytarp sails, about a $30 dollar investment. And because they all use the same cloth, they can race against each other without the "upping the ante" attitude that has cause racing to be more expensive and less accessible to more and more people around the world.

Interestingly, Michael left the hull out for last. He says the hull is less important because of the way quality foils and spars can make a good boat go faster than it should. The PD racer is a square hull and wide flat bottom. As evidenced by the messabout after the talk, it does go beautifully. Why? Because of the foils and spars, but also because the hull is light. Michael discussed the keys to making a hull light, using light plywood in a hull that is reinforced the right way, using stringers, fillets, butt joints, and interior compartments that create a light, stiff structure with nothing more than 6mm plywood. Fiberglass is heavy and Michael stressed that fiberglassing adds weight with little gain in structural integrity or even abrasion resistance. Most boats being glassed with 6oz cloth do not need it for structure and are not being used in such a way they it is needed to protect the boat from abrasion. Cloth as light as 2-oz cloth will be enough. He said that builders have also succumbed to the "upping the ante" mentality, trying to do things better and better and better than anyone else, ending up with heavier boats and poorer performance.

Australia saw another 25-plus years of wooden boat development that America and Europe did not see because of the way that market forces drove us to Fiberglass boats much sooner than they did in Oz. The result is much further refinement of glued-plywood construction and testing in the small boat racing circuits around the country. We are just now learning here in the States, thanks to Michael's generous knowledge sharing and this trip he has made to the USA.

Afterwards we enjoyed some great rowing and sailing off Portland's East End. Pictures of the messabout can be seen at the WoodenBoat Forum and at Michael Storer's own Oz Forum:

Folks will see many of Michael's philosophies played out at Clint Chase Boatbuilder in the Spruce-Composite oars, Birdsmouth masts, and soon foils, tillers, and other components made to improve the performance of customers' existing dories, skiffs, dinghies, and utility boats. Please check my website as updates will be ongoing as product development progresses and made available for sale.

De-Keeled!

I've been away much of the last month preparing for and traveling in China to unite with our newly adopted daughter. We are back home and starting to readjust. Getting back to work has been a challenge. But we got the keel off of Frolic! My brother-in-law, Hank Osborn, is a 'get-it-done' kind of guy, which is just what I needed to jump back into the projects. We have a blog for Frolic at:

www.flyingfifteenfrolic.blogspot.com.

Frolic is a 1950 vintage Flying Fifteen under restoration at Clint Chase Boatbuilder. It is co-owned with a family member and will be restored and sailing by summer. She'll join the family fleet of ff's in Gouldsboro, Maine.

Morning Row

Taking a break from the start up work for the business and the worries of how to make it all work is important for me. Moreover, getting on the water is my professional development. Using boats, thinking about how they go through the water, and trying new oars or different ways to rig the boat for sailing all matter to my finished products coming out of the shop.

Oars are a key product for my business and every time I row some new nuance of rowing and oars is realized. In these photos, you can see Portland Head Light and the stern of Drake and the oars I made specifically to Drake and my physique and style of rowing. The Spruce oars are spoon blade oars with lead in the handle so they counterbalance beautifully. These 9'1" oars are excellent in rough water because the blades are only 4-1/2" wide and have their maximum blade area outboard, providing the most propulsion. I don't need to feather these oars even going upwind. Certainly, there is more resistance but the energy feathering in rough water isn't always worthwhile.

Those two elements above won't change much. The hull form and my bodily form won't vary over time, but the conditions around me will. Wind, tidal current, waves/chop, my energy level and boat speed will all change. Upwind rowing and downwind rowing require different oars, for instance. You want a shorter oar to enable a higher stroke rating going upwind. Downwind you can use a lower rating and a longer oar and/or a larger blade area. Choppy conditions may require switching to the shorter oar. But once the wind goes calm and the water is flat, the longer oar will be more efficient. So, a good rower and rowboat needs to carry two sets of oars. For Drake, the ideal combination would be a 8'9"-8'10" spoon blade oar for upwind work and a 9'2-9'3" with a short, wide carbon blade for downwind work or calm conditions. It takes time to figure out what works for you and your boat. After a full season, I'm realizing this and luckily the 9'1" spoon blade oars have been a great all around oar to use for Drake and I.

VIP R & D on CF Oar Blades

Vacuum Infusion Process (VIP) is the name of the technique used to make composites. In Maine, this is the new generation of composites and much of our advancement in the state is owed to the North Star Alliance which administers Federal funding Maine received a few years ago and to the Maine Advanced Technology Center which trains people in VIP using world experts in the technology. VIP is easy in concept, difficult in practice: the reinforcements for the part (carbon, kevlar, fiberglass, core materials). Our oar blades are a couple layers of Carbon Fiber on either side of a core called, Soric. The core adds stiffness without much weight; the carbon gives the strength. HOW the carbon is sized, the weave pattern, the fiber orientation all impact the properties of the oar. This will take time to develop, but we believe it is worthwhile. Part of the difficulty is that so few are taking on VIP in small shops to produce part. WE ARE PAVING OUR OWN WAY!

These pictures show some of the behind-the-scenes of the process. The carbon fiber is a woven fabric like any that cuts with scissors. We cut it to a pattern a little oversize. The carbon has a stiffness to it that harks to it's eventual properties when infused with resin. Yet, it drapes like any fabric might. The shop is getting a little cool now so, to keep mold temperatures and ambient curing temperatures up, we create a warm environment with good-ol' lamps. There will be plenty more to show after the next set of blades is complete this week.
