What is best Sail design for a Catamaran?

Sad to say, I dont know the strengths of the different sail cuts and designs. And even less for a Catamaran.

Cats come complete with a stock sail from the manufacturer. Has anyone changed their sail and found better performance?

Few manufacturer's supply top quality sails on their boats so sails are easy enough to improve but for the average cruiser average sails are just fine. If you want to add a bit more zip then you can increase the size of your head sail or add a furling reacher type sail in addition to your present one.

Thanks for that. I saw a 40(ish) Cat on the web the other day with a Junk style rig and it set me off thinking......

There is no such thing as a catamaran.

There are many different boat makers who build specific catamarans. It is not uncommon for an owner to change the rig of their specific catamaran, sometimes wisely and sometimes not so wisely.

For performance catamarans a square top main would be most folks choice. Owners often add a screecher which sometimes means adding a bowsprit. Having a screecher and working jib both along with a square top can results in two slots and most likely a higher speed. Race boats will often have a selection of head sails for different conditions.

At the other extreme some folks like pinheads with a roller furling main sail and a club foot jib as the single head sail.

Choosing the rig should be done based on the boat and how the boat will be used.

Re: What is best Sail design for a Catamaran?

Best for what? Ease,? Cheapness? Simplicity? Performance? All valid questions, but all will likely have a different answer.

Well a Catamaran comes with a sail set as a 'standard' which has to cover in the main, all of the criteria above.

A Catamaran is usually somewhat under canvassed due to the lack of heel to spill wind in a gust, and I have been looking around to see if there has been any improvements or enhancements to enable a better speed/ performance generally in the generic design. (Or specific to a manufacturers hull/s speed)

I have a fondness for the concept of unstayed rigging (Freedom yachts). However they are now out of business so either the concept didnt work or it was too radical to catch on.
