Great if your boats a bit bum heavy, don't come as standard because they add drag.

We put them on, lost a knot or 2 but the boat rides massively better

They stop porpoising as well, but beware they have had adverse effects on some SIBs - do a search on here!

we had them already fitted on a SR4/50 yam we bought-all seemed ok but of course never tried boat without them so no comparison available. On the other hand we out some on a 15ft fast fishing boat for cosmetic reasons the boat was manual trim and needed to be trimmed out a bit to lift the weight of the cuddy, batteries, fishing weights and m'wallet. There was no upside as a result but the downside was the tail end would try to dive at times under the influence of the fins-- and now I had 4 ***** holes in the cavitation plate!
