Having moved from a Micro to a Marshall Cat will recommend sailing the boat loose. These boats will move much better if kept around 60 degrees to the wind. don't trim the boom in over the rail and keep the sail draft forward. If you want to sail less than 45 degrees, get a J boat. By the time you launch and rig it, I will have been to the destination already in a Micro.

There is so much to recommend with a Micro that it is easy to overlook its shortcomings. We had a good time with it.

Good luck,

Nels, I hope your friend can scan and post those photos, they are of
historical interest.
Elrow lived in Ft. Myers. I had a friend who visited him and took some
photos of him building his Micro which I still have. Sadly he died
before he finished his Micro.

I think he planned to launch it somewhere along the mouth of the
Caloosahatchee river, more inland. Of course Micro was a prototype and
Elrow was a neophyte so no way he would be able to ascertain how it
might handle tides.

One thing about cat-rigged (meaning no jib) boats is that you can pull the boom in and point the boat will up into the wind. But you slow, perhaps very, very slow.

The keel on a boat like a Micro will, in most cases, generate the lift you need to keep you from drifting to leeward, but the lift/drag ratio is low, meaning that it creates a lot of drag. So the boat will point high, but go slow. Cat sailors need to learn just how far in it pays to pull the boom. I used to compare the main to a jib; the boom has to go over the rail at just about the point to which a genoa jib would be sheeted.

It's also true the the slower you go, the more keel or cb area you need. (PCB wrote this somewhere.) In any boat, when you are trying to get going from stopped, you may slide sideways for a while. In a boat like Micro, you will need decent forward motion to get the keel into an efficient zone.

You could check your sails. Great sails (bigger too) expertly set may help somewhat. You could check out some kind of higher aspect keel. But mostly it's the topsides drag.

Here's a design instance: Otter is nearly as beamy as Micro with similar sail area, and she's as long as LM, but you could barely roll over on the cabin sole. You have to crawl and shimmy to get in there! It was designed about 25 years before Micro to be a lively and _weatherly_ sailer, and PCB wrote "The cabin can't be made higher without seriously hurting her sailing ability..." Drag vs lift, and worse in lighter winds.

Hi,
I have noticed on my Micro that she can point like other boats but
tends to drift off with leeway. When I have a decent tideway under me I
get about 100 degrees. In other words the tide acts a leeboard/keel and
really helps. When going against a tide I have on a number of
experiences found my self worse off after a tack than when I started.
In these conditions my Micro becomes an engine assisted motor sailor!

Pointing is a real bone of contention as it can make such a difference
to a journey. Quite often I leave my mooring before high tide and sail
against it to return after it has passed struggling to get back to the
mooring, If she could have just a little less leeway I would feel more
confident about sailing into the wind and getting to where I want to
go. I do not know where La Rowe for whom the Micro was designed lived
but I wonder if it was a place with little or no tide.

Nels,
Yes indeed: Dabbler Sails in Virginia. I am pleased with their (actually Stuart's) service, workmanship, speed of delivery etc. I have no reason to think my sails are not cut optimally. But I also don't have experience with other sails on my LM either so I have no other data points (sails) to compare too. When I wrote Bolger in the summer of 2008 he responded that he thought my sails might be at fault, however, I did not mention that I had mine cut by a loft, so perhaps Bolger had a vision of me sailing with blue polytarp, Tyvex, or old t-shirts quilted into a mainsail.

Recently I have seen pointing stats published in sailing magazines...a whooping total of twice. A review of the new Hunter 39 (in Sail, November 2009, pp. 33) noted that in 25 knots of wind, "On the wind, with both sails heavily reefed, we achieved tacking angles of 110 degrees. The deep keel version is bound to point higher." They were testing the "shoal" draft Hunter, which draws 5 feet.

I'm struck at times at how little quantifiable data there is on boat performance, yet there is no limit to the pontification, opining, and chest-beating. I guess this is all in line with the interweb; the CB radio of the 2000's.

WOnderful answer - i might build an LM or a sneakeasy someday.

I really appreciate your using science and measures - not just hearsay.  That nut on the end of Pugnacious ain't too shabby.

Stefan,
I have cut and pasted a response I posted on the WoodenBoat web forum this summer. I think that any discussion of pointing ability should be made with the two following cautions in mind.
1. I think people exaggerate and sometimes just lie when they talk about how well their boat points. Some people cheery-pick the one time their boat was in smooth water with a rip tide running under their keel to show how well their boat points. Or they look at the compass to determine their track. Or they just make up estimates. Except for some polar diagrams on the internet (usually produced for sailboats used for racing), there are few hard, data-driven, empirical analyses of pointing ability. The print sailing magazines almost never publish pointing statistics or (god forbid) a polar. I also think that people afflicted with boats which do not point well keep silent lest they embarrass themselves. And thus everyone thinks that there are other boats which point better and that everyone else can tack through 60 or 80 degrees. 
2. Operator proficiency and skill (i.e., the skills of the skipper) matter. Some people couldn't get a J22 to windward. Others can sail Puddle Duck Racers all over the place when larger boats are sinking and running aground. Enough preamble, here's your answer:
*****
She sails well to windward. Not great, but not horrible. I think the nut on the end of the tiller has a lot to do with boat performance, so put my experience into context with my mediocre ability to get other boats to go to windward. After sailing I look at my GPS tracklogs on my computer and determine my CMG to windward when tacking. On a Beneteau I can get a CMG of around 50-55 degrees. On my LM I can get 60 degrees. My LM will hold 60 degrees in big waves and small, with reefs tied in or not. In very smooth water in the lee of Middle Bass Island I once got her to 55 degrees CMG in a string of tacks, but those were perfect conditions. I will regularly sail to windward in the Lake while other, plastic boats are motoring. In mid-July I spent the night in Schoolhouse Bay (off of Middle Bass I., in Lake Erie). The wind was on the nose from the anchorage but I tacked in and dropped the hook without using the outboard. Every other boat motored in, some from quite a distance out. So I'm a little incredulous that people think Bolger boats are designed to motor to windward. I spend the majority of my sailing time going to windward.

Off the wind. She hauls (for a 19.5 foot long boat). Off the wind a bit- beam reach to beam run- and she will regularly hit mid-6 knot speeds and I've seen a few short stints of 7.2 knots. This summer I was following a plastic sloop (around 30 feet long) and we were both on a beam run. I kept up with them and was a little surprised I couldn't reel them in. And that's saying something when a boat 19.5 feet long expects to reel-in a 30 footer.
************ *********

I don't think that 60 degrees is great, but it works for me. But some people respond with exclamations ("60 degrees? Excruciating! "
"Death by a thousand cuts") and act as if everyone else on the water is getting within 45 degrees of the wind. Methinks not, and I haven't seen anyone posting track log files on the internet to show me otherwise. Regardless, I regularly sail to windward when many other boats (boats with magical powers to head to windward) are motoring. Bottom line- it's a great boat and I love it very much.

Bill,

If I recall, you had a pretty good loft make your sails as well? Was it
Dabbler?

http://www.dabblersails.com/

Mr. Bolger wrote about this on page 333 of BWAOM.

"Sailmakers win and lose as many races as designers..."

Also I think Peter Lenihan has mentioned that learning how to adjust the
snotter on a leg o' mutton to get the best sail shape takes a bit of
practice. You want to keep a bit more fullness in the sail than with a
standard Bermuda rig?

And have the sheets a bit freer? Or something like that:-)

Also I mentioned awhile back about the "old salts" at Shelter Island
