Is it my imagination or do the masts on Feedoms tilt like a Skip Jack ( not that much) ? I have looked at several pictures of Freedoms.Lola F30

The masts of almost all sailboats are tilted aft a bit. Some more than others.
It’s called rake and is a way to change the center of effort of the sails.
You want the boat to have weather helm, so that when puffs occur, the boat will
round up into the wind. If the boat heads away from the wind, it’s called lee
helm and can be dangerous. Raking the masts aft helps prevent lee helm.
Skipjacks and bugeyes had lots of rake partly out of tradition and also because
they had huge mainsails and long booms.
Watch how a sailboard steers. It’s done by shifting the position of the mast
fore and aft, and also by shifting the sailor’s weight on the board.

Being a x-racer (x-Impulse 21 and Flying Scot owner) I am aware about the mast rake and the controls to adjust it and its effects. I also noticed for the first time the other day, while buffing my butt off, that the rake in my F-30 is significant as compared to other boats with the abnormal rigging, stays and shouds etc. On the F-30 there are no adjustments on this boat for the rake angle, other then some minor forward tension when the jib is filled or recutting angle on the bottom of the mast. I am assuming the designer Mull whoever figured out the most advantagious position of the mast once seated (goofed a little on the weather helm problem however). However Lola have some difficults moving her mast forward or aft. Your explantion is great and I am wondering, since there are so many Freedom model and I dont know hardly any of them…are there model with fore and aft stays, or simply are there any like a everyday sailboat rigging?

As you know (but maybe Lola doesn’t) on a boat with standing rigging (wire stays
that hold the mast up)
rake is controlled by adjusting the length of the headstay, backstay and lower
shrouds.
Rake on masts that are stopped on the keel (inside the boat and down below) is
adjusted bysetting of the partners or wedges that press against the mast to hold
it steady where it passes through the deck or cabintop. On boats like mine,
where the mast is stepped on the cabintop, you can put so much rake in the rig
that the base f the mast no longer sits flat on the mast step. All ythe stress
of the rig is concentrated on the aft portion of the mast’s heel. Such a
condition can cause structural damage to the boat. Tuning a sailboat rig is a
fine art.
Freedoms (at least the ones I have seen, given my limited knowledge of the
brand) have simple and clever rigs that have less weight aloft, less windage
less maintenance and fewer points of potential catastrophic failure (a spreader,
shroud, turnbuckle, chaipnplate or clevis pin breaks, mast comes down in a
hurry). Plus the sails are self-tending. My wife doesn’t like having to tack a
huge genoa.
That is why I am interested in Freedoms and look forward to the day when I can
get one.
