  1. The time has come, we will be heading out this afternoon for the EC. I am glad that I returned from sailing to Florida as I have been working on the boat as much as I could and it is a lot better prepared than it was when I left. The lost parts have been remade. The time was not wasted as it showed me what I needed. The Spot tracker will be turned on Saturday morning and you can still follow our track on the same link http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0eHa05kYuBYnYvSIGGCbp4PpdXZchEvKn. Alan and Paul are sailing the EC22 Southern Skimmer and there are two CS17's in the race. You can follow the whole race on the Water Tribe site at http://www.watertribe.com/Events/ChallengeGMapper.aspx . You will have to look at the roster page to find their tribal names. We will be in class 4 which is for monohulls.
  2. Here are some more additions. I found that when it was cold or raining that I would dive into the cabin for shelter and dig out the wash boards and put them in place and slide the hatch shut. I decided that I would want to have their permanent stowage to be in the cabin rather than in a cockpit locker. The only place that I could find that did not interfere with lounging back against the hull was to lay them flat against the hull just above the side stringer. While they are rectangular the aft bulkhead sloped forward and the side stringer slopes downward. It was a less tight fit if the aft block was raised above the stringer. The first pic shows the washboards sitting in their chocks. The second shows the cam that locks them in place. To remove them, rotate the cam, lift the boards until they clear the lips on the chocks and drop them down. I got a few wisecracks about the other items but it starts to look organised now that they are done. I have a decent pair of 7 x 50 binoculars that I hardly use because they are stowed out of the way and it does not seem worth the trouble to leave the cockpit to get them. I wanted to be able to easily reach them, they had to be secure and the lenses need to be covered. The first picture shows them being held by the bracket upside down. Second pic shows the the bracket mounted alongside the cup holder. The third pic shows the binoculars in place. I can now use them and replace them safely and easily. The next two are obvious, pencil rack and paper towel rack.
  3. The thing that I like about the glass butt block is that it is that it is a finished product. There is no need to coat or protect it, it will be there for as long as it is needed.
  4. Alex, I did that joint the same way as the cockpit sole. I used a glass butt block on the inside of the butt joint about 3" wide and glassed over the outside. While the glass butt block had some thickness, the board thickness was starting to taper at that point and was there was no interference. I made up a sheet of glass for both parts at the same time.
  5. Alex, I will finish the repair here. The first pic shows the trunk is finished and fitting the uphaul pennant. I laid up a sheet if glass with epoxy to serve as a butt block and under cockpit sheathing. My logic was that it would connect the underside of the butt joint and seal the bare ply under the final piece in one shot. You can see the glass butt block which has already been fitted laying the bottom. Second pic shows the glass butt block glued in place. It was filleted around the perimeter through the hatch using a mirror and a gloved finger. The third pic shows the final piece glued in and ready for glassing over the top side of the butt joint and then final fairing. The question is, was it all worth it? I am glad that I did, I would have always felt that I should have done it. I had not finished the final coat of paint in the cockpit and once I did I might have been more reluctant to tear it up. I did not have a good chance to test it on the last trip as there was not a lot of tacking and there always seemed to be a current but I looked at my wake whenever I was closehauled and I believe it is better. Next week in the EC will be the real test as I will be head to head with a lot of boats.
  6. Here is the GPS mount. It started with a pine semicircle 1" thick with just a shaving or two off of the outboard edge to account for the deck camber. I needed the bottom surface to be flat, level and flush with the hatch frame. A 1/4" hex head bolt was drilled through the pine and set in epoxy for the main pivot. The GPS is mounted on a piece of 12mm ply about 3" wide and 8 or 9 inches long. You can see the GPS in it's stowed position , then in the open position and then from the cockpit but under the hatch which is where it can be used if needed to keep it out of direct sunlight. The is a wedge under the ply arm to give an upward angle. Beside the arm being able to angle,the GPS bracket allows for a 360 degree swivel on the vertical axis and it has a horizontal axis which should give me a lot of choices for different conditions. There are two large fender washers sandwiching the ply arm and it is tightened by one of our shop made starboard wingnuts. It is very firm.
  7. Okay Chick, Here is the first installment, the shelves forward. They run from the forward hanging knee to the forward bulkhead They are the width of the knee aft and start at the sheer strake aft and are level. They are wider than the knee built into bulkhead 2 as they run straight to bulkhead 1. The fiddle rail is bout 2 3/4" tall. The bottom is 6mm and the fiddle is 9mm ply and they are glued and filleted in place. I did not want large and imposing shelves but they can carry an amazing amount of stuff. I want to be able to stow light but large bulky items like that big packet of corn chips. I will drill some strategic holes so that I can enhance the fiddle rails with shock cord if I need to stow something tall. When I lean back against the aft end, the flat fiddle is comfortable against my back. I did not want a full shelf across the boat because wide shelves dump everything to the low side unless you fill it up with fiddles and it will visually make the cabin look shorter as well as impair my access the forward lockers. The hull behind the shelves was sanded before I installed the shelves for a better bond plus it is prepped for painting after I return.
  8. Chick, I do not have any pictures yet. As you know when it comes to cosmetics Beth rules, all of the parts are out being coated. I never had ideal conditions for testing the centerboard extension yet. I did watch my leeway angle at every chance that I had and I am pretty sure that it is better.
  9. Don, I did use my smartphone GPS and I liked it. I planned it as a backup but I used it when the Garmin had too much glare to read from my helm position, I had it in my pocket and could hold it away from the glare. I used it at night for trip planning because it had better scrolling and measuring than the Garmin. I thought that I would have needed it for real one day when the Garmin gave me the dreaded crash and then the black screen. I shut it down or a while and it rebooted as though nothing had happened. One of the many jobs that was not completed before I left was mounting the compass and elected to mount it along the way. I never felt the need for it while underway as the GPS with its projected course line is way superior to the compass as it is calculated from your projected course over the ground with set and drift and recomputing continuously. I did use the compass while not under way checking on wind direction as fronts came over. Alex, I had to hold my nose to put on a 2 1/2 hp motor let alone 6. My problem was running late and facing winter fronts coming continuously. There was one day when I would not have said no to another hp but I just do not want the extra size. There was one time when the motor was handy. We were ripping down the Cape Fear River with a strong fair tide and following wind. I had to do a 90 degree turn to rejoin the ICW and it became quickly apparent that if I did not use the motor I might get swept past the channel. The motor was on the lee side so there was no issue of the prop ventilating but it was interesting to hear the motor change rpm's as the puffs came, accelerated the boat and unloading the prop and reloading as the puff went away. A couple of work boats around 40 - 50 feet came up the river, entered the channel behind me and it was interesting to see how much they crabbed as they turned across current. I have put this time to good use and have made a better GPS mount which will allow me to angle the unit to any helm position as well as downward to reduce glare. I also made shelves, washboard and cup holder, pencil and binocular rack and lots of other little details.
  10. Here is the link to the last boat that we did together. Rough Point FB page The crew was too bummed out to work for the rest of this week. I am sure that she will be finished okay. We will help in any way that we may be needed.
  11. We are still reeling over the news. We have collaborated on boat designs for close on 30 years, the red boat above is one that we did about a decade ago. In fact we had just recently started on a new 41 footer for a customer in Maryland and he was scheduled to come over last Tuesday for another design brain storming session. He was always thinking on ways to improve on the building methods and loved to push the 3d modeling as far as we could so that we could use the technology by machining out as much as possible in advance to make the build more efficient. After the three of us spent a few hours together we could always expect at least two phone calls on his way home as his fertile mind was racing after leaving the shop. We have always expected this to happen sooner as he was not healthy and his brother died from a heart attack when he was fairly young. The finality is the hardest part for me. The realization that I will never be able have him visit or call him again is tough.
  12. Dave, That is the idea, I have found that I do not even need the vane when going upwind. Last year in the EC I used a 1/2 oz. nylon vane that was too fragile. Optimistically I stowed the vane below to protect it hoping that the wind might turn fair. It never did turn and I sailed more than 100 miles with the helm lashed amidships. Down wind the rudder is pretty much on center also.
  13. Tom, I want the rudder fixed to aid directional stability. Before engaging the vane, I try to find the sweet spot for the rudder and lock it. I will then observe the course after the vane is engaged for a while and may rotate the vane at the clutch or move the tiller slightly. Usually I adjust the clutch because did not have the right load on the vane when clutched. It is a powerful little vane and will tolerate a fair amount of imbalance. All self steering systems hunt so the better everything is balanced the less it will hunt. Howard, Did you see Alan's video on Carlita? He shows the auxiliary rudder. Wind vanes are not for everyone. If you do not enjoy fiddling then they are not for you. Naturally they are worthless in waterways because the wind is too shifty. It did do a great job last week running down the Cape Fear River. The GPS showed a top speed of 8.75 knots and the speed was rarely under 6, at least 3 knots of that was current.
  14. Howard, Horizontal axis vanes and servo pendulum paddles are the most powerful self steering systems and are certainly required for large or heavy handed vessels. Carlita is a light well mannered boat and requires finesse rather than brute force. If you have not already seen the self steering video, check out the video and answer your own question. She is running almost straight downwind and surfing. After this video was taken she surfed to a little over 10 knots without misbehaving. The key is an ultra light vane and very low friction. The lead counter weight weighs just 6 oz. to balance the vane. This makes the vane very responsive and reduces friction and lowers the mass moment of inertia. The next important feature is differential feedback in the linkage. This means that when the vane kicks the servo tab over and the tab turns the auxiliary rudder, the angle of the tab is rapidly reduced. If you do not have this feature the boat will hunt badly down wind where there is no natural balance from the sails as you do when close hauled. The whole thing is a delicate balance between power and feedback.
  15. I have done the stretch from Miami to home twice and some stretches many times. Once I sailed about 95% of the stretch but there was no time pressure and we put down the anchor when we could not make progress. The second time I was the delivery skipper and every day cost money and we motored for 95%. It would be easier to sail from south to north. I have not done the Great Loop but with the locks involved and going upstream up the Hudson River etc. it would be pretty difficult to near impossible without a motor.
