The Taipan often runs with less rotation than other boats. The tips giving in the taipan tuning guide are good but you may want to increase the rotation a little beyond what is stated there on your boat. Note that the two boats are using different mast sections; the crosssection of both is noticeable different with the I-17 being teardrop shaped and the Taipan mast being oval shape. The Taipan mast is much thinner (63 mm to about 90 mm on nacra masts).

Wouter, tx for that.

The main thing I have picked up so far is the difference between masts using diamond stays vs masts that do not. My understanding of the effects of mastrotation dated from my diamond-less masts - H16. It seems the effects are the other way round for masts with damond stays.

Martijn,

Nope, 35 is a fair bit older, mine is 76 and is 5 years old in Aug, I would guess 35 is more like 7-8 years old.

The yellow lines are indeed rotation inducers, I've not used them as I find they are usually more trouble than they are worth ! As you can see from my piccies, I do not have them on my boat. I sail on a lake most of the time and so don't get much in the way of waves in light wind - the rotation inducers would be useful to keep the mast rotated in the light stuff in waves !

Ok, good to know that.

Yes, that would help. I will look around to see how other
do this.

I that case you'll be alright.

Going from a diamond wireless mast to a prebend (with diamond wires) rig is a big step.

You only need to worry yourself with THOSE rotation inducers in very, very, light air. I actually refer to those as "anti-bing-bong devices" because they keep the mast from swinging back and forth in light air and chop. You shouldn't need to use these if you have any breeze.

Jake, I think we need one of those anti-bing-bong devices on this thread. I got dizzy trying to read it.

mbalhuizen,
We definitly have some confusion.

The yellow lines in your picture are mast rotators/overrotators/inducers, not limiters.
The striped line attached between the boom and the mast rotator wishbone is the rotation limiter.


General comments as to use.

Most boats have a rotation limiter of some type.
They usually have settings for upwind and downwind.

Mast Rotators are used downwind and/or in very light wind.
In light wind, there isn't enough pressure from the boom to keep the mast fully rotated,
so the inducer prevents the mast from "banging".
Most sloops don't produce enough boom pressure when running downwind to overrotate the mast to 110 degrees.
A mast rotator is usually needed.

A boat running a spinnaker needs to rotate the mast past 90 degrees to prevent mast breakage downwind.
Since they usually keep a tight mainsheet and don't travel the mainsheet very far down,
there is usually enough boom pressure to overrotate the mast properly.

There are two types of positive rotators/overrotators/inducers, manual and "automatic".
Manual rotators include the type on the boom, shown in the picture,
and the type which use an additional wishbone mounted on the front of the mast (see Murrays catalog, page 27).
This type must be manually released and then reset on each jib or the battens can get broken.
Many boats use an "automatic" rotator built from bungee cords.

Hello All,

Those yellow lines, nope, do not have them on mine.

I suspect they would be nice in light air applicaitons, if that is your conditions.

Scooby, nice pics,...your boat looks like new.....compared to a new one, yours is a bargin, do the wheels come with the price? (..do I get my commission if this post sells her?)

..

no really, both your boats look in great shape....how a boat looks new out of the box,...and 5 years later reflects on the worth of the product..

I have sail # 50, however, being on this side of the pond, my sequence may not coincide with yours, it is a 2000.

Yes, the Wheels are in the price, and yes, some sort of commission could be sorted out

Large crate of beer is the usual around here.
