What is a drifter that a genoa is not?

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.

Re: Tacking performance

I tried the cabin-top fairlead tracks on my :macx: once, hoping for improved pointing. I gave up on it. I do not remember exactly why, but I did not get the improvement I'd hoped for. Were you using the stock 100 jib? Yes, I used the 100. I pulled the genny off the furler and put the 100 on it. (Ha...

Ah. That sounds pretty doable.

Re: Route planning - how to estimate speed

I don’t want to spend 8 hours in the boat when I can get to where I want to be (5 hours), and then relax when I get there. I confess, this is me. 8 hours may not seem so much in a big cruiser with lots of room, but in a bathtub the size of a Mac, I can get squirrelly after five hours or so. It beco...

Re: Tacking performance

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 ...

Re: Tacking performance

A common mistake is to try to get back to close-hauled immediately after coming through a tack. A better approach is to let the boat fall a little bit off close-hauled with the sails a bit looser than when close-hauled. Once you have regained boat speed, gradually trim up to close hauled (if that's...

Re: Tacking performance

Also, if you want to win races in your Mac, go on races in very light winds.
Light boats like Macs will whiz past those leaden-hulled monstrosities.

Re: Sound baffling for the motor

I was doing some maintenance this afternoon and had the engine running so I measured the sound level in the cockpit. It was between 35 and 42 dB at idle. My test tank does not have room to run the engine in gear with the prop on it so I did not test it at higher RPMs. I just drop mine in one of tho...

Re: Sound baffling for the motor

Not sure why the installer of your remote control did not rig it Ah. Well. Yours is opposite mine. My raise/lower button is on the outside, and there's only a 1/2 inch spacer in there. https://i.postimg.cc/CBYZ7DCd/throttle2.jpg Also, my wheel is wrapped in black (the white wrap turned grey real fa...

Re: Sound baffling for the motor

I would say that a loss of around 15% in your previous top speed should count as being significantly lower. Has something else changed that would account for the loss? Not sure I'd trust my testing technique, really. You said that your "throttle hits the pedestal before it can max out". E...

Re: Sound baffling for the motor

The BF50 is not a loud engine. At idle I can't hear it at all just a few feet away. Yeah. It's pretty quiet at idle. That is why I think the OP's problem is an engine that is revving higher that necessary for the speed he's doing. Surely that would be apparent in a less-than-optimal top-speed. If m...

Re: Sound baffling for the motor

Take the cover off the engine. If you see three carburetors it is a BF50A. If you see no carbs it is a BF50D. I don;t know what a carb on an outboard looks like but that loks more complicated than mone. You will find two numbers stamped either on the hub or on one of the blades of your propeller. T...

Re: Sound baffling for the motor

I have the BF40. It is, for the most part, a detuned version of your engine so my measurements should be applicable to your setup. For clarification, do you have a BF50A (3 carburetors) or the BF50D (fuel injected)? Do you know the specs on your prop? I don't know. But I can find out tonight when I...

I've actually been thinking of modding my X's seat to have a low hump. I find the seat a bit low, and it would be nice to have a comfy spot when on a heel.
