The double mainsheets make it easy to flatten the mainsail  at any angle .

Hello kim,

 You have alu aft beam, Boatsmith have alu fw beam on his tiki 8m, why not alu aft and fw beams ? Wooden one are so heavy and both central beams are  strong enough ?

In my case, the aluminum aft beam was installed with the future netting in mind, and as a place to hang the boarding ladder. Having a 6mm wall, it is certainly strong enough, and likely does stiffen the sterns a bit. An aluminum forward beam, as in actually replacing the Wharram wooden beam, would have to be well-thought out. The bows, in meeting the waves first while going to weather, likely are subject to higher loads, and the lashing of the wooden beam to the hulls provides a bit of flex: a good thing! If that flex could be engineered into the aluminum beam mounts , so the bows aren't constrained on the vertical axis...
