Question: I do some daysiling and clubracing with a Cal 25 in the Chesapeake Bay. I would like to replace my old #1 genoa with a triradial. I've seen NorLam 3200 and NorLam 4500 mentioned as fabrics for such a sail. What are the pros/cons of going with these weights? I would assume the3200 would be a lighter sail, with likely a lower max wind range?

Answer: Chris -

The NorLam 3200 will offer you better performance in most conditions due to its lighter weight which has the following advantages:

• Sail flies in lighter breeze without sagging due to weight;
• Sail tacks more easily;
• Less weight aloft means less healing and pitching;
• Sail will bounce around less in light air and lumpy water.

The disadvantage of NorLam 3200 vs 4500 is its lower maximum wind limit. If this will be your only sail for all conditions, 4500 will provide durability to better survive high winds and some accidental abuse.

On the Chesapeake, about 80% of the time you can safely use NorLam 3200 and derive the benefits of lighter weight. Just use a smaller/heavier sail when the wind gets over approximately 18 kts. apparent speed.

Good luck,
