Stus-List 35 MK I Mainsheet and Vang
I just now unrigged the mainsheet and replaced it with a 4:1 mainsheet and cam cleat that I had as a preventer for a proof-of-concept. The preventer has been on the boat for so long I forgot where it came from, but looking at the mainsheet systems online and at Bacons it became obvious this IS a mainsheet so I decided to try it out. So far it has only got a light air test, I am loving the lack of friction compared to the stock system that goes up to the mast and back to a winch. My question is this; will 4:1 be enough? Bacon's has a 6:1 mainsheet for a reasonable price, I can buy that and send the 4:1 back to preventer duty easily enough. While I was at it I noticed the vang, one of those Quick-Vangs with a spring, had the line fed through a turning block far enough from the mast that it had a significant change in tension as the boom swung. I have no idea how I haven't stared at this for decades and not noticed, the yard installed it ages ago and I just never realized they did it wrong. Now the line feeds to a turning block almost at the pivot point, changes in tension will be almost nonexistant. Joe Della Barba Coquina C&C 35 MK I Kent Island MD USA

Hey Joe, IMHO, Four to one may be underpowered for heavier wind, unless you take it to a winch. Not sure if your traveller is mid boom or end of boom. The system on our 34R is end of boom and we have 5 to 1 course and 20 to 1 fine and the higher ratio is needed when she's powered up which is anything over 8 knots going upwind when the apparent wind hits 14 plus. Saw something online that showed some boats like J-105s rig their mainsheet five or six to one for high wind days and unreeve a block and convert it to four to one for light wind races. You may want that mainsheet at Bacon's.

Joe, My 35-1 has a 6:1 purchase on a Harken traveller, and I have to pull reasonable hard to get the boom tight in any kind of breeze. I don't think a 4:1 would do it. That said, in light airs the 4:1 would be nice. Maybe you could use 6:1 but drop it to 4:1 in light airs, which, having sailed out of Annapolis for 5 years, I know you get a lot of in the summer.

Stus-List 33-2 companionway hatch and turtle
Good day all. I must be looking for things to do because I'm pondering how I might improve the companionway hatch. The acrylic is crazed and requires replacement, and I've also noticed some of the turtle (fiberglass cover/housing) screws had loosened. I've disassembled it, and documented it on the blog, follow the link below. There's a bit of dirt under there but everything appears to be in good shape. I've detected no issues however I do wonder if it ought to have drainage holes other than into the cockpit. It appears to have had some sealant (butyl?) installed between the turtle and coachroof, however it was certainly not sealed. Perhaps it should not be sealed to the cabin top at all? Though there is no indication of water ingress, I will drill out, epoxy-fill, and redrill the mounting holes. The teak rails and stop block appear to be in excellent shape. The exposed teak is in good shape however it is subject to weathering and is not easy to remove for maintenance. Has anyone else gone down this rabbit hole, and if so what improvements are worth making? Thanks, Dave 33-2 Windstar http://cncwindstar.blogspot.com/2022/10/companionway-hatch.html

I had 7:1 purchase with end boom sheeting and ratchet block at the bridgedeck traveler and that was bearly enough at above 15 kts apparent on my 35mKII. She had a higher than normal aspect ratio mainsail owing to the slightly less than 12 foot E dimension. I think 4:1 won't be good in anything but light air and definitely not good for not so strong trimmers.

Stus-List Re: 35 MK I Mainsheet and Vang
4:1 is not enough in heavy air. As you increase the purchase (6:1), you will have more friction which makes it more difficult to ease the sheet in light air. Also, as you increase the purchase, you will have a longer sheet, and it will take longer to sheet in and out. I have a 4:1 purchase plus a mainsheet winch. The winch gives me the extra strength I need in heavy air, and the 4:1 (rather than 6:1) lets me sheet in and out faster. You have to decide what is more important for you.

Great advice! I think I will grab the 6:1 sheet and the 4:1 can go back to being a preventer. If I really wanted to I guess I could swap them out as desired.

I would recommend a 3:1/6:1 arrangement with double line, something like this: https://www.dropbox.com/sh/aktbkuov19c4q9y/AACSrPhw1Xq758Tk8U7fae1ea?dl=0. All blocks are Garhauer. The special double block, double cam was around $75. Mine is a 27 ft boat, so the forces are respectively smaller. Originally, it was a 4:1, two-ended, with one end on the cam cleat and the other on the winch. Going upwind in any fresh breeze, there was no way I could trim by hand (at least, not easily). With the 6:1, I never had problems, even at strong winds. The 3:1/6:1 arrangement eliminates the issue of having too much line for e.g., gybing. NB. I don't think this would work well with a dodger.

Stus-List Cleaning the Garage
Over the past couple of weeks Ive been sorting and reorganizing in the garage, and I have some stuff that I dont need or want to keep, but that may have value to another C&C owner. Before I discard things, or offer then to a local boater resale shop, I thought I would offer them to the list. Here is an initial list of a couple of items: A Blue Sea Systems Automatic Charge Relay. Part number 7610. New, never used. I bought it for a project but decided that the 120 amp max current flow would require humongous wires because of the long run between my house bank and the battery forward that powers my head and anchor windlass. Donate $50 to Stu and it is yours. Ill even pay the shipping and get satisfaction to having it be useful instead of sitting on a shelf in a resale shop. I have converted Imzadi to a propane stove and oven it was a major task to replace the original pressurized alcohol stove and build lockers for the propane tanks. I recall that, before the conversion, I had real problems finding parts to repair one of the burners. So I suspect someone could use parts from my stove as spares. My stove is a 2 burner Galley Maid stainless stove and oven that was standard on the 38 mk2. I also have the pressurized alcohol tank that was part of the system. I think the stove gimbals are still attached. Shipping the whole kit and caboodle would be expensive, so if you need parts and make a donation to Stu, let me know what you need and I will ship it to you and recycle the rest of the metal. Someone told me that Loran remained in operation in Canada (and the Great Lakes) after being turned off in the US. I remember that my fishermen friends were pretty upset at losing the accuracy and repeatability of Loran down here. If Loran still works up there, perhaps you have a fisherman friend who could use the Apelco DXL6350 system that I removed from Imzadi. I even still have the whip antenna that goes along with the system. One night a couple of years ago, someone decided they needed the 3 ½ hp two-stoke Nissan motor for my dinghy more than I did. Ive replaced it with a 3 ½ hp Nissan, but still have some spares from the old motor. One box has a 3-blade, 7.4 dia x 5.7 pitch prop (part number 309641060M) that fits the 2.5 & 3.5 hp Nissan and Tohatsu 2 strokes. (And Mercury as well, IIRC) I also have shear pins, cotter pins, and zincs. I think I also have a carb rebuild kit and some other engine parts, but havent founf that box yet. Make a donation to Stu and they are yours. The marina I run used to have a lifejacket loaner program in conjunction with the local Sea Tow franchise. We wound up with a bunch of life jackets after the owner of the Sea Tow franchise retired. Ive donated all the adult and youth size to local sailing schools and museums for use on their boats, but I have a couple of child and several infant size PFDs left. If you know anyone who could use one or two, let me know, and they are free to a good home. Tell me how many you need and Ill pick out the best of them. Any that get left over will go to the Salvation Army, but I doubt there would be much demand in their resale shop. Im sure I also have some removed deck hardware like mounting chocks for spin and whisker poles and metal winch handles, and some 3 and 4 cowl vent scoops to replace any that have jumped overboard. If you need any of this, contact me off list and we can arrange shipping and a donation to Stu to support the list. Rick Brass Imzadi C&C 38 mk2 #47 la Belle Aurore C&C 25 mk1 #225 Washington, NC
