  1. I have been wanting to do this for a long time to speed up my packing up and unpacking the boat but other jobs had priority. I watched Jay packing up his rig and he inspired me to get it done. I measured the gap between my two masts in their trailing position which turned out to be 1 1/4". The main mast being in the tabernacle puts the track down and head aft. I elect to stow the mizzen mast with the track facing up and head forward. This makes the masts about level athwarts where the crutches need to be for stowing the sprits even though the tracks are on opposite of the mast. This is because the mast diameters are apposite where each of the sprit crutches need to be. I made the crutches out of 3/4" ply and it takes about 3 feet of 1/4" shock cord for each crutch. It takes just seconds to move the loop of shock cord under the masts while gathering the rigging and passing over the top of the sprits and putting the loop into the slot. There is no tendency for the crutch to fall over and the setup is very firm when both shock cords are secured. Like Jay and Chick, I leave all of the lines attached except for what I need to undo to remove the sails. Where I differed is not pulling the sprits up the masts but let my snotters go to the stopper knots. This puts them on the deck making the masts easier to lower. If anyone wants I can email them a pdf of the crutch shapes, they can adjust it to their mast stowage setup. I have not sealed them yet. I will pad the bearing surfaces when they are coated.

    Hi Jan, Welcome to the forum. You are doing very nice work. Thanks for sharing the pictures. I am looking forward to watching her grow.

    Hugh, You can come and camp whenever you want. Oyster, Damn! Why didn't suggest everyone should do some sanding earlier, we do not have anything ready.

    Core Sound 20 Mk 3 -- #4 "Chessie" . .

    Peter, She looks like a proper yacht tied up in the slip at St Michaels. I look forward to seeing you both this weekend.
  5. Great trip Peter. Back in the late sixties Lake Cootharaba for Easter was my favourite place in the world. For those that do not know about it. It is only about 6 miles long and 3 miles wide and 4 feet deep. There is only a huge sand dune between it and the Pacific Ocean. I see on Google Earth that there is now a town there. I remember just a camp ground with minimal facilities. After parking and launching your boat there were no cars, only lots of sailors and boats. It was a four day party with lots of good racing. It looks like you are training a great crew.

    Chick's Micro Power Cruiser Project.

    Tom, You know what I think about ballast in a powerboat. I am looking forward to seeing the Old Codger. Alan asked me last week how I thought she would float, I answered " by the stern" and he said "I think so too". Of course I had prior info, Chick told me that he was going to steer with the tiller. Maybe we can talk him into some sort of bulkhead steering system. It would be more agreeable when he does the Great Loop. She is so light that her moment to trim would be small, maybe a few cans of vienna sausages and a couple of Linda Ronstadt tapes stowed in the bow will trim her out and leave the stones ashore.

    Outer Banks 26 #1

    Ken, I thought that it would be cool to make a wooden latch to hold the door open. Here is my first draft. It would latch automatically, and to release, you reach to just below the seat and bend it to starboard. I would make it out of a springy tough wood like ash. I would put on a thin stainless striker plate on the door so that it would not wear your varnish.

    B&B Preps for Florence

    I talked to Tom on the phone the other day. They went inland for the storm. He was heading home and the most pressing issue on his mind was cleaning out rotting food from the fridge. His house is high and well built but his shop goes under water. He has a scheme that lifts all of his machines above flood water but I am sure that like us, there will be a layer of mud and lots of flotsum to clean up and there always seems to some stuff that is missed during preparation. How did you fare Oyster?

    CS20mk3 for family camping?

    Hi Foxwedge, You have been given good advice so far. I just recalculated the displacement at the datum water line for fresh water and got 1507 lbs. It takes another 405 lbs to push the boat down the next 1" evenly. I think that you could put 10 kids on her and she would carry them safely but you might not feel the same. Amos has two kids and I am sure that he has some good cruises planned.

    Core Sound 20 Mark 3 Build - Chesapeake, VA

    Hey Amos, Love your color scheme, congratulations. Look forward to seeing the boat and family at the messabout. Fred, That is exciting news but a little stealthy, how about some details of the launch?

    Core Sound 20 Mark III #3 "Jazz Hands"

    Steve, If it will work out better for you, fly into Newbern. One of us can pick you up and return you to the airport. If you want to bring your sleeping bag, you can sleep on Chick's old OB20.

    B&B Messabout 2017

    Dale, I have not talked to Alan about the date but I think that it will start Friday October 19. We used to have it on the last weekend in October but with winter approaching we tended to have worse weather than the week before plus it often clashed with halloween. Unless Alan feels that the date clashes with something more important, the 19th of October it will be.

    upwind sailing

    Tom and Dave have given you good advice with the sheeting of the sails. Pinching is definitely not the way to go but so is sailing too full. There is another important adjustment and that is draft control which is adjusted by the snotter. I see a lot of skippers with way too much draft and pinching, complaining that their boats won't go to weather. The picture you posted of Paul's boat is close to what you want. As Wasserboot said you have to play with your adjustments to see what works best for the conditions. I would start in a moderate breeze and sheet the mizzen as Tom suggests and set it flatter than you have done before and sheet in the main also set pretty flat until the mizzen starts to backwind. Sail like this for a while and do a few tacks sailing as close as you can without pinching and see what speed your speed and tacking angle is. Then ease your snotters to draft up the sails in small increments to see what speed versus tacking angle is and then ease your sheets. You should now be on your way to figuring what your best settings will be for that condition. Lighter or choppier conditions will require you to sail a bit fuller. This is done by easing the sheets slightly and adding a little bit more draft. The other thing I want is to dial in about three or four degrees of weather helm. If the main has too much draft you can get lee helm and too flat will create weather helm as well as sheeting the main in too much. It will be the reverse for the mizzen. A bit of weather helm generates more lift than drag and it also encourages you to sail close to the wind as you will see the main start to luff when you lose concentration. Lee helm causes you to sag off to leeward which is not fast if you want to get to windward. Properly sailed, the cat ketch should be competitive around a course.

    B&B's first annual "Capsize Camp" July, 20-22

    Randy, It has been a long time since I did stability calculations for the Belhaven. I was thinking recently that I need to see if I can even find them and revisit the calculations and bring them up to date. I recall that the 80 degrees was a very conservative number because I was considering a worse case situation like crew falling into the mizzen sail etc.. With feedback and experience I know that you have a greater point of vanishing stability than the mk3's.

    Core Sound 20 Mark III #3 "Jazz Hands"

    Steve, I like to mill the tops of the coamings 1/8" below the the underside of the hatch and use 1/4" gasket material as Chick says. Alan and I have debated at length on how to handle this and decided that 1/8" is about as close a tolerance as we could expect a home builder to consistently achieve. I like to set my trim router with a straight bit using it as an end mill and trim the coaming tops precisely 1/8" below grade. I do not have any deck to support the the inboard side so using a chisel and block plane work it down to grade. If the cockpit coaming is already installed you have to work the back coaming as you do for the front. It is only 6mm okume so it is not that hard to do. You can round over the top edges and it will look good and it will be a little easier to compress the gasket. When I lift up my hatches I can see a perfect indent all of the way around the gasket. I know that blind hinge mount would be nicer but I have not figured how to do it. After a while I do not even see the flat piano hinge in the big picture.
