Pulled the daggerboard out of 'boat' just last week and gave the thing a good polish with fleet wax. Looks great, real slippery. It's sure was easy to take it out - I just stand over the hole, push the mast over a little with my knee so it has a slight bow in it, and slide the board righ up and out of the hole. Going back in was just as easy. Had a centerboard on the old boat and now that I have a daggerboard I don't think I could go back. I had no idea how easy they are.

BOAT - I'm trying to envision this. You loosened your forestay before doing that, right? So you could lift the mast up and sideways, or move it forward a bit? I hadn't considered lifting the DB out while the mast was up before.

Sounds like he had his mast down at the time. Ya it is easy. Replaced ours last year on the water (in harbour). Took ten min.

Last summer with the boat on a mooring had to replace a damaged DB and didn't want to drop the mast, so I inserted the DB from beneath the boat. Had to fight the current a bit, but only took about 5 minutes!

Do you have a close-up shot of the bowsprit? I have a brand-new assym and bowsprit from BWY but haven't had the chance to use them yet - any hints you can provide on how the bowsprit is best mounted would be great.

I've got a trade show to do in Tacoma, WA next weekend and am taking the opportunity to drag the M there for a week - then in June will be taking her to Bayfield, ON for a family get-together, hopefully will have time to get up to Georgian Bay. Can't wait for these trips - so far, opportunities to sail the M have been way too limited!

Here u r its a 3ft bowsprit that I designed & made yrs before & BWY copied my design in a smaller size :x

Sorry, I forgot to mention that the mast was down. Do you guys have a cable on the trailer that prevents the DB from hitting the ground?

Thanks for that - sorry to hear of the backstory. I haven't even tried to fit mine yet but it's quite a bit smaller and flimsier than yours, that's for sure -

OK so I know this is an old thread that has somewhat gone on a tangent...but hey we're all sailors and like to go where the winds are shifting to.

I was curious based on the earlier data in this thread and did some measuring using my gps track. Sailing my :macm: upwind in 15mph winds (waves travelling with the wind in Biscayne Bay) I was able to measure an angle between tacks of 105 degrees. This means I can sail 105/2 = 52.5 degrees from directly in the eye of the wind.

I can maintain about 3 or 4 mph speed in these conditions. If I try to point higher I start losing speed to the point that she just doesn't steer or is going too slow (barely attaining steerageway).

I was using my furling genoa (fully out) and was using a full main (not reefed), heeling about 20 to 25 degrees most of the time.

As was mentioned, this is all true wind, not apparent measurements.

I was wondering if anyone else has done a similar excercise on their M?

Do you folks think I'm doing ok with these results or should I try to improve upon them? I'm trying to develop my upwind sailing abilities. Any thoughts are welcome...... thanks!!

I get about the same maybe 1 and bit mph faster as I get 4-4.5 knots over ground on GPS in those conditions. I have a custom loose footed full battened main with heavier weighted cloth than the factory original, this may account for the difference. Weather helm is extreme and the gusts cause the boat to heal to 30+ and round up. I find furling the genoa to jib size reduces heal and weather helm making the gusts easier to manage, speed remains unaffected.

Yes there is one on mine, thin, but sufficient for its purpose. I look at it as a "safety" backup cable, as oppposed to something intended to be used to relieve the tension on the DB support lines. Thought about putting a wooden (like a 1X4) board across during storage to take the weight off of everything, but the DB is so light I don't see much advantage for the trouble to do it.

That sounds about right - 105 degrees in a tack. Maybe 110.

Hello, To compare boats I have taken a different approach.

As an ex round-the-bouys racer in mixed classes in off-the-beach boats I am familiar with the "yard Stick" given to each class of boat.

The Yardstick is a number calculated over several season's racing results to provide a correction factor which enables race times to be corrected to theoretically make all boats equal. Therefore any differences in corrected times being attributable to sailing skill, not the intrinsic speed of the boat.

The higher the number the faster the intrinic speed of the boat.

The corrected time is arrived at by dividing the actual time by the yardstick.

Assuming the Royal Melbourne Yacht Club handicaps work the same way then I feel the Mac performs very well.

eg Noelex 25 0.725 vs MacGregor 26 0.715 Not bad for a boat with this much accomadation and a lot of windage.

Perhaps the Macgreggors slow reputation is based on its poor windward performance which is compensated for on other points of sail.

For yardsticks

Opps, think I made a mistake there.........You must MULTIPLY actual time by handicap to get corrected time.
