I have certainly missed your updates on the progress with your project Keel.
Tom Spohn Provided information and all pictures and links to the La Perla Noir Performance Upgrades on the BWY MacGregor M Model Boat.
They say the Standing Rigging on a Cruising boat lasts longer than the Racer because it is not tensioned as the racer chooses to gain every bit of performance, but I also think it may be from the very large oversize rigging found on a cruising boat, at the cost of some performance. Many here on the board have mentioned a wire tension gauge to manage suitable Rigging tension. Loos Professional Wire Tension Gauge from Frank C Post It might be a good investment considering the benefit you stand to gain from the your new weighted DB. BWY Experimental Boat Custom Parts and Equipment
BWY Experimental Boat Construction
The heavier Dagger Board should benefit your ability to stand up in more wind, creating more power. BWY Experimental Boat Sailing
I noticed the BWY experimental boat changed out their SS 1X19 5/32 swaged standing rigging for some lighter composite rigging, and it is said to be as strong with considerable weight savings.
I noticed a recent article showing a drop in the price of this rigging. Just a thought as there is considerable benefit to be gained from removing weight aloft, as I believe there is a potential gain represented as 5lbs at the upper part of the mast is equal to 50lbs at the Keel. No doubt the reason BWY removed the head door and probably used some very light composites to replace the interior head panels, table, and are careful not to overload the boat when challenging or demonstrating the Sailing Prowess theyve built into their project boat. I note the running backs and Composites Sails add to the weight savings and even more to the windward performance.
Notice the "Self Tailing Winch" on this boat
Composite Rigging may have some extra wind resistance when compared to the Factory SS standing rigging, and I have seen it mentioned in Trimaran and Cat upgrades of considerable larger boats. Im believe the benefit might be marginal for the cost of the standing rigging, and I had thoughts about the weight of that Foam in the M spar, and anything to be gained (or lost in the benefit of not turning turtle) but take a better look at the windage from larger halyards and topping lift, if it is in the budget. I might buck up for a set of those radial cut composite sails to benefit from their lighter weight, but more their ability to hold their shape in higher wind, keeping their center of effort forward for more drive.
Im sure you noted the Roller Furling on the BWY experimental Boat, and no doubt the composite Jib was cut flatter to better their pointing when combined with their running back stays.
Note: There is no sewn on Roller Furler Cover, Much too Heavy
I note these may conflict with a Bimini top and their attachment to the genoa track may be more a convenience than using the base of the rear stanchions.
At any rate Ill bet there is considerable backing for the structural pull of the running backs under the deck?
Tallying up the cost for the New Keel, Composite Standing Rigging, New Low Windage, low stretch Halyards (and I would eliminate the Jib Halyard if your running the RF and install the Spinnaker Halyard block platform well above forestay hardware on the mast) eliminate the topping lift with the addition of a boom kicker to support the boom and its new outhaul setup. The new Sails will benefit from a Cunningham Ring and Flattening Ring with suitable blocks and hardware to control their functions. I might just mention now would be a good time to set up some simple jib Block controls to benefit the new flat cut radial composite jib, to allow you to power up, or down the jib blocks, from the cockpit, as the Sheeting angle of the Jib is so much more efficient sailing on the wind, especially with your new low windage running backs keeping the forestay at its best. This setup may just benefit from BWYs new bearing replacement upgrade for the M Spar, to reduce rotational friction brought on by the shrouds and running backstay tension.

Seems your boat has the Etec 50 already and is appropriate for maintaining a nice balance for Sailing and Motoring and I so appreciate you sharing your adventure into performance upgrades of your new M. These expensive modifications are on the cutting edge, and BWY and Delevi must be commended for their spirit of adventure along with many on this board for reaching beyond in gaining improved performance.

The Black Pearl project however fascinating as it may be is not for the average Mac sailor/owner.
Yes, there may be lessons to be learned from the experiments performed that an average Mac owner can benefit from.
But I think we get carried away and forget that most of us got a Mac for what it is.

When tightening the upper shouds, remember to release tension on the lowers. Forces act in tandem.

They Theirs,
As for the keel project, check this thread
http://macgregorsailors.com/phpBB/viewt ... c&start=15
I don't quite have the boat bucks to turn my boat into The Pearl, but I am planning on getting running backstays when they become available. I heard this is coming in the near future from Macgregor. Some nice sails are also on the future shopping list, though I heard that the ones they use on The Pearl are optimized for light air (not a good match for me.)
By the way, the rigging for their keel looks bullet-proof. Makes me cringe to think that I'll be hauling a 180-200 lb keel on the stock DB rigging, though they have a 500 lb keel and a bulb which is always in the water i.e. probably high loads while motoring. I hope the stuff holds up to the weight of my keel, when I finally get it.
Octaman,
Thanks for the rigging advice
Cheers,
