Re: Storm jib for CS30?
justin forkix -
If you would take your request to just about any good sail loft, they would measure the position of each reef position in your mainsail; and then, 'balance' with the appropriate jib shape and jib sail area to match each reef position already there on your mainsail. This of course assumes that at or much above 20kts, you are reefing your boat at these windspeed.
The CS30 is probably raced in your area so the boat designer's detailed / combined sail plans will probably be on file at most sail lofts.
This will allow the selection of any smaller jib to 'match' the balance (helm balance) of your boat vs. the mainsail being 'full up', 1st reef, second reef, (maybe a 3rd reef).
An alternative is to measure each reef position distance - from the boom to each reef - in your mainsail .... and 'some of us' will calculate the new approx. required 'balance' (combo of sail area and geometric configuration) between a new smaller jib and your already installed reefing configuration. Then when you get 'our' basic recommendations, you can look in the used sail market in your area for something 'similar' and close to the sail area and shape preliminarily recommended ..... and you will probably have little to no 'helm balance' PROBLEMS with a 'new' (to you) smaller jib bought from a used sail outlet.
1. vertical distance from each mainsail reef position from the boom
2. The approx. heel angle that your boat makes when 'beating' in (fill-in the blank) wind speed .... and how with many reefs youre sailing with at that reported approx. heel angle.
3. How much wind strength do you 'want' to sail in?
I checked with the online CS30 'owners manual' (very detailed!!!) but missing the detailed designers combined 'sail plan' sketches. This would be a detailed sail plan sketch/drawing that has a little circle with an + within the circle (CE) imprinted on the mainsail ... and on your boat would be located just aft of the mast and about 1/3 'the way up' from the boom. So if you, or anyone else here, has such a sketch (with *combined centroid of sail area* - CE - w/ 100% jib), it would be 'really' helpful to reply with such calculations/estimates and initial recommendations.
