1769.0. "Spinnakers" by RIVAGE::KELL () Fri Aug 02 1991 09:14

	Having just bought a cruising boat which has all the rigging for a 
spinnaker but does not actually have a spinnaker, I thought I would ask for 
comments and advise on buying a spinnaker. The boat is a 35' ferro-cement sloop
so I am not looking for racing advice but cruising advice. Also can someone tell 
me the pros and cons of radial, tri-radial, star, symmetric and assymmetric 
spinnakers.

    very briefly...
    
    Radial cut ( i.e all seams run horizontal ) is the simplest, and
    probably the cheapest. Should be fine for running and broad reaching,
    performance would be very slightly lower than more expensive racing
    designs. However, should be fine for cruising.
    
    Tri-radial ( i.e. all the seams radiate from the three corners, meeting
    in the middle with a few cross cut panels ). Just about all racing
    kites are like this. They offer much better reaching performance,
    particularly close reaching, but are more expensive.
    
    Star-cut. Similar to tri-radial, except without the cross-cut panels.
    fairly rare.
    
    Asymmetric. The principle advantage of these are they don't need any
    extra gear ( poles etc. ), as they are flown like a loose luff genoa,
    but if you already have the gear, don't bother. The downwind
    performance is lousy, mainly because you can't push the tack up to
    windward ( which a pole does )             
    
    On a cruising boat, aesthetics are probably quite important. I happen
    to think that tri-radials look better, but if you are not racing, the
    cross-cut sail will probably give you enough extra performance, for
    less price.
