I guess they help dampen fore and aft pitching on short boats in chop, do they assist in early planing? I remember talking briefly to a guy with one on a national 12 at the dinghy show but we were more focussed on the gizmo he had on a gybing centreboard.
Then I guess there must be downsides if the boat heels badly won't they increase braking effect and turn dramas into crises during sketchy downwind transitions? (Gybing). Interested to hear from anyones experiences. |

I think they are very good for clearing the floating weed from our lake in the summer.

A video of a study by the cherubs. Obviously only a snapshot, but looks to affect the flow coming off the stern.

A mate of mine who has a DCB design says the t-foil makes the boat far more stable in terms of pitching. Gives him the confidence to gybe in extreme conditions too due to the boat being much more stable.
It tricks the boat in to thinking it is longer than it is. Whether that assists with early planing or not I don't know. There must be a drag element though (not to mention weed).
