This is only partially responsive but may be enlightening and hopefully, fun.
Almost 35 years ago, after consultation with Bill Lapworth, we replaced the main mast with an excellent internal furling mainsail system designed by Alan Blount.
While you gain a great deal, you do lose the sail area of the roach with this modification. So Bill suggested we offset that by making the mast taller by 3.5’....”more than that will make the boat tippy”.
We also added a furling staysail and running backstays. Unfamiliar with running backstays, I asked, ‘How will I know when I need to use them to avoid pumping?’. To that, Bill responded, “You’ll know!” I now know. When in use, the entire rig is much more stable.
Well, Ariel has now sailed for many years as a ketch rigged Cal 46 with internal furling main and mizzen, as well as a furling jib and staysail. We have sailed from MdR twice as far South as Manzanillo and three times as far North as British Columbia and into Desolation Sound, leaving her there for an extra cruising season or two.
She balances beautifully, points very well for a 46 and goes downwind well. But tacking (which is what you asked about), THAT is a skill we have not been able to master. The staysail, so good in heavy weather, makes that admittedly pretty ugly if not almost impossible. For our sailing, I will take the staysail over a club footed jib.
