 Centreboard Up/Down Control Use |

  Joined: Tue Mar 13 2007, 08:21PM Posts: 89 | My boat (8860) has an up and a down control for raining the centreboard in the case (ie. the centreboard pin can be raised so reducing the board depth under the boat). We never adjust it - the controls just lock the board full down when sailing. Does anyone use this control and, if so, when is it used? As far as I can see its main benefit (to me) is when putting the board back in the case - no problem locating the pin. I have a Milanes High Aspect Gybing board (if that makes any difference).

Boat was easy to sail and fast. We switched to a smaller Waterat board, and found that our speed was the same but we were not quite as high as we were with the board all the way down. We now just leave it all the way down too. Mike | ||

My first hi tech boat, Floys, was set up by Mike and had a old spitfire board that could be moved back in the case but not up and down. She was very fast in a blow up wind with the board well up and the nose down! The new boats 8552 and 8834 have had the long boards but not with the lifting pin. At my standard it feels like these go a lot higher but I am still lifting it, on the standard pivit pin, when the wind is getting to the fun range to balance the boat. Can you/do you pivit the board when the wind gets up with the drop down option? Mike, In real breeze ( 2009 worlds ) was the board all the way down as the starting point. Finally I am thinking of a new boat, is your thinking lifting pin and long board or not? | ||

If you think about your fixed centreboard bolt being raised in a slot inside the case (max 8 inches as Mike said) - just raises the pivot point. Not sure when this became standard (slot in case) but it may well be so on new boats. We rake the board in a blow upwind (10-20 degrees) and also downwind as we are quite light at 22 stones total. New boat? That will set you back 12 months - may stand a chance!! Tony | ||

We then rake aft to a maximum of 2.5". This is not very much. We did a ton of two boat testing and found any more than that and we lost height with no gain in speed. We get to 2" at about 18 knots. To de-power more we concentrate on the rig. Barber hauling the jib out to within 6" of the gunwhale, rig back as far as the mast gate will let us with the ram (strut) down all the way. Cunningham as hard as I can pull it. Easy kicker if still over powered. Mike | ||

But the aim wasn't to lift the board up in the boat, the beak of the centreboard had two holes drilled, when windy the the forward hole was used pushing the board back in the case. Seemed to work ok for Mark and Ian at Hayling Island! | ||
