  1. Scott, Yes, same as usual.
  2. We started the little Suzuki yesterday for the first time this season and I believe that the Chick method works. I went through the standard starting sequence and gave it about 4 pulls, then Alan gave it a few pulls. He then blew down the fuel fill and she roared into life on the next pull.
  3. I too think that Chick might be on to the problem. My Suzuki 2.5 has been the perfect engine except for the first start of a cruise. Once it has been run for a while it starts every time on the first pull. I am not keen on kissing the inside of a fuel cap but I know that I will become desperate enough to do it. I want to start mine soon so I will give it a try. I wonder if I can cobble up a cap with a hose to make it a bit more sanitary. Paul, I am glad that you got out for a sail. Your weather should be getting real pretty now.
  4. I am lined up to go. I am 25 miles from Potters Marina so I will sail up on the 14th. John worked out a nice cruise. The weather has been crazy this spring so far but there is plenty of opportunity to refine the cruise as the weather dictates.
  5. Peter gave you good advise. Having built these boats for over 40 years or more, my usual standard was to coat the inside of the trunks on Spindrift's with three coats of resin and call it done . On bigger boats I always glass the inside of the trunk sides before assembly. Alan pointed out a while ago that it maybe quicker to glass the the trunk insides than do three coats. It can never be bad to have better abrasion resistance. So the upshot is that, coating or glassing works, but glassing should be better. The other issue is glass taping the trunk to the bottom. Again this is a complicated issue. It is always better to glass both sides of a joint. The problem is that, as been pointed out, it is hard to taper around the inside of the trunk bottom slot so that you do not narrow it and do not get any bubbles in the glass as it does not like to go around tight corners. I decided that it was too hard for home builders to do well without a lot of pain, so I decided to eliminate the inside corner taping and double up on the fillet and inside taping. I stagger the two layers of 3" tape by 1/2". We ended up with a pretty competitive S10 racing fleet so instead of cutting the bottom slot to the trunk rectangle we cut out the bottom to match the profile of our dagger board to have less turbulence. This would be impossible to tape inside without a lot of work. I have never seen a failure in one that was done this way so far.
  6. This subject keeps coming back. There are many ways to measure strength and one of plywoods greats properties is that being a low density material it's stiffness to tensile strength to weight ratio is close to ideal. For instance, if we were building an aluminium Spindrift and trying to keep it from being too heavy, we could look at 16 gauge which is a cigarette paper thicker than 1/16" or 1.651 mm for our mathematically challenged European friends. Now if we compare it's weight to 6mm okume, it comes out at about twice the weight per square foot or meter. That already is a pound or kilo too far for me to cross already, not to mention that the bottom would probably need stiffening with a couple of stringers, compounding the build by a lot of extra welding. We do not even need to factor in that aluminium does not float. The Gougeon Brothers used to have great display at boat shows.They had every material that you could build a boat out of. Each piece was cantilevered 12" past the edge of the table and was exactly 1" wide and weighed the same. They varied the thickness of each piece so that the weights would be exactly the same. When the same weight was placed on the end of each piece, people were amazed to see how much stiffer wood was compared to the other materials and compared to steel, which we all know is very strong. The only way to beat wood is to lower the density further and that means to use a core material. As we have seen that can work but a little more resin here and there and we have lost the weight battle. A little extra weight is not a big deal in a work boat but in a tender that has to be manhandled a lot in often awkward conditions, it is a big deal.
  7. I have no problem with a few worts. I would rather them than than have nothing. It is the beginning of the learning curve. I also subscribed to their channel because I love to see their Spindrift living and doing what I intended. I have sailed those waters and it is a lot of fun to see what has happened with the yacthing explosion. In 1975 I cleared into Pukhet in the commercial harbor. The chief of police strongly recommended that I not stay in the harbor as thievery was a problem and told me about a good anchorage, there were no marina's. I was the only sailboat in the area.
  8. I will add my 2 cents worth for plywood versus composite materials. I built my first Catspaw stitch and glue in the late Sixties. We could get thick epoxy for gluing but the the only resin available to me was polyester. She was used for full time cruising which meant that she was in the water if we were not under way. By the end of 1970 the glass tape was de-bonding from the ply even though I used isothalic no wax laminating resin which bonds better that orthothalic resins. I cross hatched the bonding area with a piece of saw blade and primed the wood before laminating. She even got marine borers and had to row with our feet over the borer holes or we would have a tiny fountain. I did the obvious thing and built a masonite female mold and laid up a fiberglass hull. I stiffened the bottom and gunwales with foam. She was a bit shorter to save weight but she came out heavier. It solved the problem with water but it was not as tough as her wood predecessor. While the glass boat was better against sharp objects, she could not take hard use and abuse as well as the wood version like getting crushed at the dock etc.. By 1980 she getting tired and looked like a patchwork quilt from repairs so I decided to build a new 4mm okume plywood Catspaw but with epoxy this time. She was much better than her fiberglass sister and served me well, became the boatyard work dinghy after I quit full time cruising. Around 2005 a friend borrowed her and lost her in a hurricane. She was no great loss as the ply was getting soft. She was not sheathed and spent all of her life in the weather. Don't get me wrong, I love composites and will use them in a flash if I think that it will be better. I like to see experimenting. Plywood has the advantage that it is cheap, user friendly, light and tough. I sincerely hope that you can hand your carbon Spindrift down through generations but only time will tell. Here is a picture of a Spindrift 9 nesting, working hard for her owners. They are about two thirds of their way around the world and I suspect that after they finish, their Spindrift will be ready for another lap with a just a modest refresh. https://sailwiththeflo.wordpress.com/our-dinghy/
  9. I have gotten pretty intimate with the 5.80 plans recently so I will attempt to answer these questions. I have seen and created all or some of the above suggestions but I think that Don has struck the right balance for this boat. It not a gunkholer and never will be. It is a no compromise deep water boat. The keel profile is a heavy steel plate that also has the bulb profile. There is a heavy steel flange curved to the hull rocker which he wants welded by a certified welder (there is so much weld length that I would be very confident of my welding). This flange is bolted with 5 pairs of bolts through 5 heavy oak floors. The lead bulb is made in two halves with three large bolts bolting the three parts together. The bolt holes in the lead are counter bored for the heads and nuts, and faired with a soft filler so that it can be dug out. The idea is to have a simple strong structure that is the ultimate in simplicity, strong, reliable with the maximum righting moment for the weight and not interfere with the limited interior. It can be trailed but needs to have a deep ramp to launch. I have trailed a J22 which was possible but restricting. The keel can be all easily unbolted and man handled if necessary, say to get it into a container or long term storage.
  10. On looking a little closer I see that the 3/4" x 1" cleat that tops the side bulkheads is not installed yet. it connects the side bulkhead to the seat.
  11. You are still going at an incredible pace and with very nice results. I see that everything is done for installing the seat tops real soon but I see one omission that I hope that you just have not gotten around to yet and that is the cleats on the forward bulkhead and the transom. They support the ends of the seat tops and go between the side stringers and the side tanks.
  12. It is interesting that I am finishing up installing a fuel tank under the cockpit and moving the battery forward on the Original OB20 hull #1 that Chick built. The reason is because I bought an almost new Etech 50 that sat around for 10 years and have finally installed it. Remember that after this version the bottom was redesigned with more volume aft for bigger engines so that my need to get weight further forward is relevant to to just this boat. The old fuel tank was about 15 gallons set on the port side back to the transom. I cut a big hole in the cockpit and put in a FT35 35 gallon tank set against the pilot house bulkhead. I hate the idea of burying the fuel tank forever but I wanted the keep the cockpit watertight. I hope that I never get a wave into the cockpit but I want to be able to hose out the cockpit or what if debris clogged the cockpit drains and it rained a lot etc.. I installed the tank with the fuel gauge fuel pickup and filler forward and made a rabbeted kidney shape hatch rabbeted to take 6mm lexan cover which I will set in mastic that I can pry out to access the hardware, like replace the fuel gauge sender or clean out the tank. I do not have access to the tank vent as it is at the other end of the tank but I have the exact dimensions so that I could put in a 4" diameter lexan hatch if the need ever arises but I doubt that will happen. With the fuel pickup forward, the engine will quit if I am on plane before I use the last few gallons, this might not be a bad idea as I will have somewhere between 5 - 10 mile range at displacement speed to get me somewhere if I am stupid enough to run her out of gas. I put the battery on the forward side of the bulkhead with a lift up step to give me instant access to the battery. As the battery (group 31) is heavy and the space is too tight to lift straight up, I put a sliding front that lifts up so that I have more room to work inside the compartment. The battery is held by a screw down base and the wood bar across the top locks the battery down and the screw through the starboard cleat holds the bar in place. The three way battery switch is over kill but it is one that I had. I put her in the water yesterday and she trims out well.
  13. I adjusted an eyestrap to fit the bolts of the lower rudder gudgeon and fastened an eyestrap to the aft end of the trunk about 3" up from the bottom. I put grommets in some 2" webbing. I used some 1/8" cord to connect at each end and used the cord to adjust the tension to suit.
  14. I am sure that the new Marissa will have a happy owner. Thanks for all or your posts, you do not realize how important it is get good feedback so that we can continue to create, especially someone with your level of craftmanship and to see you add your own interpretation to our designs.
  15. We always strive to make our kits as good as we can and any constructive criticism is very welcome. Without feedback it is hard to improve. The fact that we design and use and cut our kits we can very easily make changes. One of the problems is like with the daggerboard change. Finding and fixing the instructions which can go back many iterations to avoid confusion.
