<p>hi roger,</p>
<p>i have a tikki 21 with standard rig. sounds like you are too tight on your rigging. mine are not much more that hand tight.</p>
<p>Sounds like that will be vibrating in a 'B sharp'</p>

<p>Hi Rick,</p>
<p>You are right - the section is closer to 3' but with double wall thickness at 1/4".</p>

<p>Hi Roger,</p>
<p>What is the diameter of your mast? From looking at your pictures, the mast appears to have a smaller cross section. I built the standard wooden mast with a four inch cross section according to the plans and have no problem with mast whip.</p>

<p>Thanks Kim. Yes, I can experiment with less tension. The good thing is that I can tighten the rig until the side stays become tight, and the boat goes to weather very well. I would still like to hear from another Tiki 21 owner if the mast whip is just a characteristic of the 4' mast.</p>

<p>Dial it back a notch, Roger, and see what happens. I take two halyards to the bow/stern(at separate times) and snug them up a bit, then I take a line and "frap" the halyards as high as I can reach. This pulls the mast towards the respective end, and then I tighten the lashing, and release the halyards. It may be that the 4:1 purchase allows you to overtighten the rigging.</p>

<p>PS I get my rig really tight with a big 4:1 purchase on the fore stay. In fact, it only vibrates when I have it really tight. Maybe I'm overdoing it?</p>

<p>Hi Kim,</p>
<p>Thanks for the feedback. The standard alu mast section for the 21 is 4' and 1/8" wall thickness. My mast is a bit under 4' at 3' something, but is double wall thickness at 1/4". It will be interesting to hear from a Tiki 21 sailor with an alu mast.</p>
