Love Tim's and Allens work and I shoot a similar (somewhat laid back version)here in San Diego. Have used a 5.5 XS RIb for the last 4 years and before that a 14ft achilles and even earlier a 12' zodiac.
Find the pod helm seat with backrest is ideal. You can stand and hold on with your knees and brace against the back rest,for a steady shooting position.
Don't quite have the "nippy' factor of "photoboat"
Don't usually have the extreme weather of some of the other guys, so shoot Canon equipment without protection.
20D for rougher weather and 5D for the sunny clear skies days. The RIB has a good high bow and the only time I have come near to a soaking is from jet skiers "rooster tails and so called friends from blighty !! Thanks Matt and chris
