My 2010 has cabin top racks for the foresail.

Excellent point!Dimitri-2000X-Tampa wrote: ↑Mon Mar 25, 2024 4:59 pm Lots of good comments on how a mac compares to a keelboat but also don't forget that the headsail type makes a big difference on a mac. Most of us (myself included most of the time) use a genoa sheeted outside of the shrouds. Whereas if you use a 100% jib (like the stock jib) sheeted inside the shrouds (using cabin top tracks), I've noticed about a 10 degree improvement in pointing. Even with keelboats, a shorter bulb keel doesn't typically point as well as a fin keel which doesn't point as well as a full keel.
If running overpowered with my genoa or if I need to point better I use the cabin top fairleads. Since I roller furl it is easier than changing sails. That is the one and only thing I don't like about furling. The M is so much more tender, running to the bow is a LOT different that on my V25. I am still getting used to how it seems to be more tippy. I also bought the genoa track fairleads with cleats. A game changer if anyone beside you wants to sit in the cockpit. BWY has them. Other than that furling when you need it is irreplaceable.....KBDimitri-2000X-Tampa wrote: ↑Mon Mar 25, 2024 4:59 pm Lots of good comments on how a mac compares to a keelboat but also don't forget that the headsail type makes a big difference on a mac.

I believe they are the same as Bill’s EZ-Cleats. Many of us have been using them for years. As you say: .I also bought the genoa track fairleads with cleats.

A game changer
As the saying goes: "If you're wondering if it's about time to reef - it's time to reef."Stickinthemud57 wrote: ↑Tue Mar 26, 2024 6:46 am The question then becomes when to reef, and the answer is before you set out. Reefing on the water is doable, but difficult. It is easy enough to shake a reef out while underway, so when in doubt, reef. Generally speaking, when winds get above about 15 MPH you are going to be much more comfortable with the mainsail reefed.
Were you using the stock 100 jib? If you tried doing it with the genoa for example, it would not work as well. The jib is a much flatter sail than the genoa so not only do you get the advantage of the cabin top tracks being quite a bit inboard from the genoa tracks, but you also get a much flatter properly shaped sail that will point a lot better (and do much better in higher winds than a partially furled genoa - although I will sometimes run a partially furled genoa from the cabin top tracks to point a bit better but still not as good as the jib because the loss of shape).DaveC426913 wrote: ↑Mon Mar 25, 2024 7:26 pm I tried the cabin-top fairlead tracks on myonce, hoping for improved pointing.

Standard procedure for me is to reef at the dock and then strike the sails. Once I have a clear shot out into the Gulf they come back up. The only real question is, "One or two reefs?". It's a lot easier to shake one out than to put one back in when you are the only one on the boat.DaveC426913 wrote: ↑Wed Mar 27, 2024 8:11 amAs the saying goes: "If you're wondering if it's about time to reef - it's time to reef."Stickinthemud57 wrote: ↑Tue Mar 26, 2024 6:46 am The question then becomes when to reef, and the answer is before you set out.

But even that's a bit risky. Reef *before* the wind builds. Yes, reef at dock. You can always shake it out.
Yes, I used the 100. I pulled the genny off the furler and put the 100 on it. (Had no choice; my furler is my forestay.)Dimitri-2000X-Tampa wrote: ↑Wed Mar 27, 2024 8:29 pmWere you using the stock 100 jib?DaveC426913 wrote: ↑Mon Mar 25, 2024 7:26 pm I tried the cabin-top fairlead tracks on myonce, hoping for improved pointing.

I'm not sure it would even be possible to put a 150 genny on the cabin top tracks. It would billow like a spinny!Dimitri-2000X-Tampa wrote: ↑Wed Mar 27, 2024 8:29 pm If you tried doing it with the genoa for example, it would not work as well.

I did BWY's Big Jib rigging and sail mod, and have since traded my 150 genoa for a 150 drifter. I used to run the sheets to a block on the track, but my tracks ran aft almost to the winches, so that's an important factor. I found that I could run close hauled with a few inches of sheet to spare between the blocks and the winches.DaveC426913 wrote: ↑Mon Apr 01, 2024 6:57 am I'm not sure it would even be possible to put a 150 genny on the cabin top tracks.

What is a drifter that a genoa is not?Stickinthemud57 wrote: ↑Mon Apr 01, 2024 9:04 am I did BWY's Big Jib rigging and sail mod, and have since traded my 150 genoa for a 150 drifter.
A drifter is essentially a lightweight genoa. Being made from .75 oz nylon, it fills much more easily in light breezes than a genoa of the same size. It has a heavy rope luff, so it hoists on its own halyard set at the top of the mast. So, yes, if you have a spare halyard up front then that's how it is typically flown (as opposed to hanking it to the forestay like a regular jib). I found it is a little difficult to manage when taking it down, so I made a dousing sock for it. Much easier. Drifters can also be flown from their own furler, simplifying their use even more.DaveC426913 wrote: ↑Thu Apr 11, 2024 8:28 amWhat is a drifter that a genoa is not?Stickinthemud57 wrote: ↑Mon Apr 01, 2024 9:04 am I did BWY's Big Jib rigging and sail mod, and have since traded my 150 genoa for a 150 drifter.
It sounds like a cross between a genny and a spinny.
I wonder if I could run one up the spare halyard in a light wind.
