I would highly recommend you check out the Pompanette one-piece fiberglass (e-glass) outriggers mfg. by Pompanette here in Newport Beach, CA.
12 footers run $890 incl bases and fully rigged with Aftco release clips- also the best relase clip IMO. If you want super stiff check out their 13' "Hawaiian" model. Despite fear of offending the back East crowd, I have to say that aluminum sectional outriggers have nothing to recommend them- unless you like dealing with the inevitable problem of corrosion. They are also prone to damage if you misjudge the tide and go under a low bridge with them in full upright/stowed position. My Pompanettes are about 12 years old and still look great on their 4th boat. West Coast style all the way, for sure. Dare to be different...
