Bruce,
<br>
<br>Three things to consider. In order that I would try.
<br>
<br>First Downhaul- let it off and reapply it until the boat is just under control. It is important to have it on but if you have applied more than needed it can kill the boat
<br>It bends the mast too much and the top of the sail lays off too much and stops working (you said it was fluttering). To make it work you increased sheet tension which may also make the leach in the bottom of the sail a little too tight.
<br>This boat will feel very easy to handle but a bit like you left the hand brake on.
<br>
<br>Second look at rotation.
<br>If I carry too much on my Taipan it can affect the boats inclination to drive forward and hence slow you down.
<br>
<br>The last thing I'd consider is back to the outhaul. Possibly 3 inches is too much.
<br>
<br>I hope this helps.
<br>Phill <br><br>
