What lens are you using? it shouldnt be too bad.
IMO Keef - if its surf photography your main things to look at are...
AF speed , the xxD range is better than the xxxD range for canon up untill the 400D which is as good as the 30D. 40D is better but way put of budget.
Framerate - combination of how fast the SLR can shoot (xxxD = 3ftps, xxD = 5fps, except 40D = 6.5fps), and how quickly it can write these to the meomory card + its memory buffer size. the 300D (old) is let down here, compared to the 350D its slow. the xxD cameras are a lot better.
Also depends what you shoot, fast surfing I usualy shoot jpg (normaly shoot RAW, much bigger) , on the 350D I can shoot 25+ jpg's continuos.
Lens. For surfing your realy going to want a 'fast' lens with minimum of 200mm reach, more like 300-400. Some of the best surfing shots I've seen are with a 600mm prime but thatsthe cost of a good car.
lenses also have a veriety of focusing motors. How good (read expensive) thse are affect how quick it'll focus.
Hang11's 70-200F4L with full time/ring USM focuses very fast. My (old) 75-300 is terrible and I wouldnt even take to to shoot surfing. the 70-300IS is a LOT better.
