New Guy with a Centerboard question

Postby Wino10542 » Wed Sep 25, 2019 5:25 pm

Hi all...I picked up my DSII about a month ago and have been lurking around reading as much as I can. So...after a "shakedown" cruise that didn't go nearly as well as I would have liked (the bunks(BOTH!!) ripped off the trailer upon launching to start..so that should give you an idea how things started) I have a question. The CB got stuck..I couldn't lower or raise it and after getting the boat home and up on blocks I could see that the U/H cable got wedged between the CB and trunk just like I have read it is prone to doing without that shock cord, which snapped, to keep tension on the cable. I dropped the CB, straightened and cleaned things up and put it all back together. I can raise it easily by pushing the CB up from underneath, but when I try to raise it using the U/L I find it very hard to raise. So...here's the question: Will it be easier to raise it once the boat is in the water?. I'm hoping the water makes the CB a little more buoyant and easier to raise. If this isn't the case I'm open to any suggestion/opinion as to what the problem may be or what I should do.

Thanks,
Evan

Welcome to the forum!

Maiden voyages are apt to have an unanticipated moment or two, but it sounds like you've used up more than your quota :) Glad you and your boat made it back sound and safe and you're still interested in making this go.

Can you move your CB by hand from underneath more easily than with the UH? If so, that would mean you might have more friction in the UH line than you should. A CB is supposed to not weigh more than 25lbs. If it's almost horizontal (and no friction in the pivot, or against the CB hull) it should require a push of around half that to move it up. If it's noticeably more, that would be a clue. If you can extend it all the way down, try pushing it back. Any resistance in that position would be contribution from friction.

Contribution from weight should increase as you raise the CB. Is that what you observe? Buoyancy will take some of the load off, but I haven't sailed a DSII often enough to have a first hand feel for that.

Does your uphaul mechanism use a set of blocks (pulleys) at the bottom of the mast tube, or is it a direct 1:1 pull? My 84 has the blocks which give a 2:1 advantage for lifting.

Hi all.....I do have a pulley setup on the CB, but I don't know what ratio it makes it. I'll have to mess around with the CB some more, but there doesn't appear to be any friction when I raise the CB by hand from underneath and there is a slight amount of side to side movement of the CB so I don't think there's an issue of friction between the CB and the trunk.
On a different note, when I dropped the CB the plastic wedges slid right out. There was no sign of any adhesive or caulking that I have read other people have applied or found on them. Should there be something on these wedges?

Thanks

I have the very same issue with my CB. I, also, have a 1984 Daysailer ll, and neither of the control lines moves the CB. I have it on a trailer now, getting ready to store it for the winter. I will try and rework the CB next spring, and will try and get the boat up on sawhorses to work on it. I have read many past posts, and believe that I may have to unscrew the metal pivot point under the boat, in order to reroute the lines. I am the third ( ?? ) owner of the boat, I have unused blocks near the base of the mast, along with two grommets that go into the cuddy near the trunk. I think that these blocks were used to raise and lower the CB. The previous owner did not use the blocks. I have not seen any pictures that show how to utilize the blocks properly. Any help with this is appreciated.

ON ANOTHER NOTE: This is the second time I have loaded my boat on a trailer for storage. When I lowered the mast, I have broken a spreader, EACH TIME!!!
Aside from feeling like a dummy, I am not happy about the money I am burning up, doing this. I am obviously doing something VERY WRONG!! What is the proper procedure when stepping down the mast?? Once I have it lowered, and try to move it forward to the trailer support, I get the spreader " caught " on something and snap it. I NEED HELP. Thanks.

I got my CB reinstalled with new cable. Tomorrow I'll get a photo of the uphaul rigging and post it here.

I too have a '84 DSII and had great difficulty raising the cb completely up into the trunk until I invested in a good pair of sailing gloves. The uphaul would always slip in my grip the last few inches and almost cut into my hands. The sailing gloves eliminated that problem and I could raise the cb completely. It requires a considerate amount of pull on that uphaul. My advice is to get you a good pair of leather sailing gloves. My pair have the exposed finger tips. hth John

Jim,
to post a photo, it won't work to give the file name on your local C:\ drive.

You can edit your post (or write a new one) and on that page, where you are typing the new post there's an "upload attachment" tab below the text field.

You can upload a photo and then click "place inline". That method works quite well, but you may need to resize the image a bit (the forum doesn't have automatic resizing like the social media platforms do).

If you need more info, look into the the "How to use the forum" part of the forum, there's a post on how to post images that goes into this in some greater detail. So far, most everyone has managed to figure this out.

Congrats on your purchase! I just bought my '72 DSII a couple months ago. Just did my first "shakedown" cruise last weekend. Write-up forthcoming but I too had some issues w/ my CB.

In my case, my downhaul was "off track" and got jammed between the CB and the trunk, locking them both in place. Ultimately I decided to take a swim and manually pulled the CB down from underneath. Once down I was able to pull the board down and didn't have any issues the rest of the day. Despite this after getting her back on the trailer I looked underneath and once again the downhaul seemed jammed against the trunk. Curious to see what happens the next time I go out.

I got the below pages courtesy of Rudy at D&R Marine. I mentioned the issue when I was ordering new standing and running rigging.

Not sure if yours is configured the same way but thought I would share in case they're helpful.

Jim, I see your uphaul has an added block to double the advantage. The standard set-up is more or less just a turning block with a shock cord attached to keep tension on the uphaul cable. I like your set-up and going to have to try it. Thanks for posting the picture! JOHN
