Hi everyone



as well as owning "This way up" I also own a composite boat sail no 6698, (we beleive it to be a rhondar) which we have christened "winter folly" having now got it so that it doesn't leak in the tanks or round the bailers and repainted the hull, we are now in the process of tuning it.



We have modified the control lines so that we can put them onto the thwart rather than in the back at the rear of the centre board casing, (that was always "interesting" trying to adjust them in strong winds) however I wonder if anyone can help with a measurement for the base of the mast from the transom?



In regards to adjustable rigging there are no facilities to attach anything to have adjustable shrounds , but the hull has reinforcing for shroud levers so I am also after a pair of those is possible?



many thanks

Hi Paul



I think the easiest and quickest pointer is to ask you to look at the topic raised by Gordon Scott (Gybebunny) on shroud adjustment. It covers the options for above and below deck pulley systems. I have some pictures of a replacement system for quadrant levers by fitting stainless steel plates that spread the load and allow pulleys to be fitted in place of the quadrants. This is then triangulated down to the mast foot to finally be fed back (as per John Woofidens diagram). Hope this helps.

Hi Paul,



The Rondar boats are foamed cored and there is not many of them around. If it is single ply GRP then it is more likely to be a fosrite.



The best thing to do with the mast foot is put it as far forward as your allowed in most cases. This measurement is 10ft 11 inches from the front side of the mast to the outside of the transom. If you look through previous posts there is a discussion on this.



Also with respect to to the shroud levers i suspect you mean under the deck? if this is the case then the shroud quadrents as they are called are a no no as they have a tendency of exploding, hence no body uses them any more. I think this is also discussed in another post. If i have got the wrong end of the stick and you mean above the deck then a pair of above leavers is more than adaquate as long as you can move it down a peg or two when it is windy.



Hope this helps

Oh no they are not! Agree on all the other points though.
Paul, if it is your green boat that you brought to Maidenhead this year, then I am pretty sure it is not a Rondar, more likely to be a Fosrite. I will dig out the photos to see if there are some clues there

hi john



Yes it is the green boat I brought down to Maidenhead, but it is no longer green, 40 plus hours to scrape the green paint off!!!



Its now had a coat of blue paint and is a lot smoother on the hull.



I have a pair of flyaway levers fitted to release the shroud tension going downwind and have had rings welded onto them to assist in releasing and putting tension back on and can alter the position using the multihole fittings but not on the water.
