Quick question...I have a trifin with asymmetrical thrusters. Should I mount the thrusters flat sides in or flat sides out?

flats in. i've come to realize that the waves have to be rather steep and fast breaking to want to use multi-fins, but that's me. more for side off conditions. i need instantaneous top speeds, and great upwind power in most of my wave spots. onshore conditions have a following current that take away early planing and top end, so do multi's. bad combo in my experience.

the number of side off dayz i get are few, but when it does happen, i typically try to use a smaller single fin on a larger board to overcome the gusty nature of the wind bouncing off the dunes, and condo's.

Flats inside

it has to do with the water flow mostly in turns.

May work the other way( would think not very well) but to me would be the same as hammering in a nail with the wrong end of the hammer.

Is all side shore here,a little bit side on, but I'll mostly use it in the gorge anyway.

One or both of us is confused about your last sentence, Chaco. The Gorge is all "onshore", meaning the swell is created by and travels with the wind. Some (by no means all) types and makes of multi-finned boards offer plenty of advantages here for many (by no means all) sailors in many (by no means all) conditions for many (by no means all) objectives. Like everything else in the sport, there are pros and cons for virtually every option.

I was talking about the coast with the shoreness. I mainly want to use the board because its a poly board and it has the trifins, so might as well try that out too.

That's what I thought. Ingerbritsen's comments used "onshore" in the conventional wave-sailing sense in which all Gorge winds are "onshore" ... wind and bumps traveling in the same direction.

No worries mchaco, I understood what you meant. The wind is sideshore to your normal launches. isobars likes to think that swells in the Gorge are like surf, so you might say he is a bit confused at times.

I'm in agreement that the thrusters should be oriented so that the flat sides are in.

I just meant the oregon coast is usually sideshore Laughing But I probably would have refered to the gorge as sideshore too since thats how I thought about it at the lake where I first started.
Sounds like flats in is the way to go, at first I was thinking flats out like a hobie cat, but hobie cats dont bank, and if the outside fin is popping out of the water the inside fin should probably be flat in...anyways ill try it out this weekend and might even see how it does as a surfboard on the coast Very Happy

Yeah, flat in for the holding power and what you pivot off of on your turns. For severe downwind current, some sailors use bigger inside side fins.
