    Ocracoke 256 #5

    Congratulations Tim and Crew! Well done. She looks fast just sitting there. Would love to know some specs. What size Mercs? what size props? let us know what speeds you're getting when you've had a chance. Here is a spreadsheet where I've recorded some specs from the other two Ocracoke 256s hope to build up some more data for comparison. https://docs.google.com/spreadsheets/d/1ZBs7Ee-KrTDGdYsIP6pUZla0snSo73GKc-xbaQC_E00/edit?usp=sharing

    Ocracoke 256 hull #2 Build

    Aegean_Sea, Please accept our apologies for the lack of response from the shop. We've been really swamped lately and got behind in our email responses. I have sent you a reply and look forward to working with you. -Alan

    Steve, that looks good. The tabernacles are glassed around the tops (specifically around the pivot bolt) in order to back up the end of the wood there and strengthen the area around the pivot bolt. It also builds up the thickness on the inside to meet the diameter of the mast. Ideally the tabernacle only touches the mast at the pivot bolt and at the bottom so it doesn't scrape the inside walls when you raise and lower it and the glass at the top accomplishes this. Glassing the entire tabernacle isn't really necessary but I've started doing it for (as you say) protection of the wood. When I do it it usually takes at least 2 steps. Glass around the outside and over the end grain, Then the inside separately and overlapping the first round on the end-grain. I did the CS-15 tabernacle this way. I'm pretty sure I put a couple of extra little round patches on the inside to build it out to match the mast diameter.

    Broken Finger Joint Repair?

    Amos's reply is pretty comprehensive. Looking at the location of the break (they often break on the corners which is less of a big deal as you say) a butt joint repair with a tiny scrap piece i think would be fine. You could put a small piece of glass over it on both sides for peace of mind. Wont matter for the inside and can be sanded completely off on the outside before glassing the hull.

    Thanks for all the response! Keeping us motivated and glad to hear keeping others motivated as well. On working with epoxy and cleaning up with acetone. I've tried vinegar in the past and for me it doesn't do the job. For skin contact with epoxy we use denatured alcohol when we have to followed by just a hand washing with soap. We are working in an enclosed garage since it's cold out so we wear 3m organic vapor respirators at all times when working with epoxy. If you smell acetone vapors, you're doing it wrong! And the epoxy vapor coming off a coated surface can be pretty strong too. We're also wearing gloves when working with epoxy so dipping a brush when finished into a jar of acetone to clean it and blotting it into a rag while wearing a respirator and gloves we feel is not a health issue. Getting acetone on our skin is not what we're doing here and should be carefully avoided. For cleaning putty knives we use a chip brush to clean the knife with acetone while holding it over the jar. Knife in one gloved hand, brush in the other. All the acetone falls back into the jar and the brush and knife are cleaned and then wiped onto a rag. It's quick easy clean and minimizes contact with everything. (the rag eventually gets stiff and is tossed). Once the jar of acetone is too dirty it will solidify into a solid and the whole thing is tossed. Jars are plentiful and found in abundance in our recycle bin. We like pickles! Working carefully we rarely get any epoxy on our skin. Not trying to brag and yeah it's impossible not to get covered in sticky when you're laying down big long pieces of cloth or tape but there are ways to avoid it as much as possible like laying everything down dry and then apply the epoxy instead of wetting it out and then trying to move it. And keeping extra gloves in your pocket so if you get it on your glove you can swap it out instead of getting it on the tools you're holding. I treat my gloves like they were my skin which keeps my tools from getting sticky and helps teach clean working habits. Finally, mixing sticks are basically free, cups are cheap and brushes are pretty cheap so if you are REALLY messy I can see how your best bet would just be to toss everything after each batch. I think everyone's got to come up with their own system and this is ours.

    Mistake with stainless steel fasteners

    Steve, Easy answer is nothing. The way I see it there is no way to 100% prevent stainless steel touching the aluminum either on the backside (inside) of the tube or in the hole walls if you miss a spot with your duralac or other corrosion inhibitor compound. That being said, i don't think it's as big a problem as most fear. As an example, after the failure of Southern Skimmers lower mast section in the EC the other year I was keen to inspect the inside of Joe and Sally's EC-22 mast which is built to the same specs. We used a boroscope tool with a smartphone to take video of the inside of the tube focusing on the rivets and bolts that poked through and the general condition of the aluminum inside. We found little to no corrosion other than a normal surface layer. Nothing to worry about AT ALL. There was no more corrosion around the threads and rivets than anywhere else. By contrast, Skimmers mast failed because it had a large sleeve of carbon, glass and epoxy glued into the lower section at the tabernacle as reinforcement and insurance just in case the thin wall tube was too much on the ragged edge of the safety margin. The mast never failed but the sleeve kept water from capsizes trapped which corroded the tube badly until it failed.

    hahahahaha. Too funny. That will teach me to add fine print and an expiration date! Doh!

    I'll add that I was also surprised that this is sufficient before I had a more complete understanding of how strong a layer of 10oz glass really is in tension when used this way. Also, Graham noted that we make sure the tips are a good fit to the board and I think that is an important detail. If there was a tiny step in the joint and it was not smoothed out with thickened epoxy just prior to applying the glass sheathing then this could weaken the joint since the glass fibers are not nice and straight across the joint. I use a 4" putty knife and pull it across the joint with moderate pressure to fill any low spots just before applying the glass. you'll be able to see/feel any "step" in the joint though so you'll see if this is necessary. Another important detail is to use fill coats of epoxy (2-3 of them) over top of the glass cloth until it's nice and smooth and under no circumstances would I sand the board into the glass. After your fill coats, then you can sand without getting into the glass and do the final fairing with micro-spheres or primer. Here are some pictures of a board I did a couple years ago. This one was for Doug's CS-20 Mk3 which was hull number 1. I only used a single layer of 10oz cloth and I did wrap it all the way to the bottom of the lead but as Graham said, that doesn't really do much good as it wears off after only a couple of groundings. I glued my tip on horizontally but only because i was being greedy with my time and wanted to glue the tip on and then immediately apply the glass to one side. (i was in a hurry) http://sailnaway.blogspot.com/2014/04/a-little-side-project.html This is a great question and I will add a more detailed picture to the plan sheets showing the glass layers as Graham described for our next victi...I mean builder.

    That sir, is a fine looking vessel. I await your first sailing report with anticipation. I have heard the rare comment that some do not prefer the lines of the flush deck cabin on the MK3 design but i just don't see it. Looks very sweet to me.
