I know everything ... but have a rudder question.

2. He appears to have a "non-stock" setup. Standard setup appears to be one or two vertical sliding blades in a carrier. Tiller with linkage setup. His appear to be fixed and reinforced.

Guy has guts.

I wonder what kind of rudders this guy had?

The question is not what kind but "how many?"

From the photo, it appears like there is only one. If there are two, the one that is visible does not appear to be close enough to the starboard for a second.

Yep had major Mods done for the trip lowered boom extra shrouds , extra sealant around all joints , cabin was sealed up so tight it was extremly hot inside with very little ventilation

PS Ray wear ur glasses I think it,s closer to S/B check out this link & u,ll see two rudders
http://northman.pl/en/home/
They make a 21-22-24-26-28 & two 33ft versions , the 33ft has a 10.5ft beam

U can get a RS version what ever that is I,m thinkin a racing version ?, a fixed keel, twin shoal keels, center board , or dagger board

That 21 footer looks to be built very much in the JOG (Junior Offshore Group) boat, those things are best part of bullet proof, of course there is a price to pay and the price is weight.

My JOG boat the hull was best part of 1/2" thick fiberglass, it had 320Kg (700lbs) of lead in a skeg keel and a steel lifting centerplate, the rig is not overly large to reduce weight up high, she had 5/32 rigging all round and a baby forestay for added mast stability and just for good measure you didnt want to do a solo mast raising, it was one thick heavy cross section.

All up the tiller seems to be the weak spot on many boats, I can recall reading MANY reports that the tiller has failed and they have had to jury rig up a new tiller, the actual rudder gear seems to be pretty tough

I'm wondering what it looks like when it's actually sailing - how come no videos of it actually underway under sail? That's the only way I can judge a boat.

I’ll make my appointment with an opthamologist when I return.

I like very much the system tehy use as MRS, watch video 1:18.

The MRS is alltime fixed, you don't have to carry around and do not have to fiddle around with the forestay pin.

Also very nice the trailer. You dont have to put the axles in the water.

Could we do this also with our 26 footer? watch video at 3:25.

I think we have such a boat on the lake here.

Don't recon that hull will last long before deforming or delaminating with the full weight of the boat on those small diameter keel rollers if its foam cored which I would presume it is.

A friend had to throw their hull out on their foam core 16 footer because the rollers had deformed the hull and caused delamination of the glass, the repair bill was more that the value of the boat by a considerable amount.

In theory a tilt trailer could be used, they were popular in the late 70's early 80's but seem to have dropped out of fashion. they used to tilt from the draw bar

[kurz]

well you just could use the rollers to slip on/slip off. To store or when trailering on the road you can rais up other suports (Langauflagen).

I guess one problem could be: The trailer gets to heavy for some cars...

[sailboatmike]

I don't see why a X or M couldn't have a complete ladder of keel rollers the full length of the trailer, the keel rollers would take the weight and you could use bunks or rollers to support the sides, this would make the boat far easier to launch in way less water and stop the need for the mac bump

I'm in the process of adding a bow roller, just behind the little vee-bunk, to aid getting the bow into the vee-bunk. So I don't have to sink the trailer as far into the water, which in my marina puts the goal post totally under water. And they're longer than the originals.

Probably won't help with the Mac Bump®, though.

Also going to add a short length of angle with a wood block on it in front of the mid bunk suppport, to prevent the CB from dropping behind the mid bunks if (ok, when) I Mac Bump® it too hard after forgetting to fully retract the CB. Done that twice so far.

But some rollers sure would be nice, along with the Liquid Rollers I use on the bunk carpet.

The hull on the 2013 was specifically modified for the trailer - maybe even earlier models too, but I don't know.

The modification was a spline molded into the hull right at the spot where the dry hull rests on the trailer bunk. The bulk of the hull rests on that spline (it's right about midships aft and runs port to starboard under the rear dinette seat) it makes the structural support for the dry hull into this "T" kind of configuration:



It's really quite remarkable when you think about it - the entire weight of the dry hull is balanced on that line that goes across the boat under the aft dinette seat!! It's really counter-intuitive and makes you wonder what the hull the factory was thinking when they created that? We would need Tom to calculate this but to me with the motor hanging off the back counterbalanced by the entire weight of the 300 pounds permanent ballast to the front that point is it about where the center of balance would be if you tried to balance the boat on the head of a pin - Why would they do that??? It's crazy! They have the whole boat supported at the heaviest part on ONE BUNK!!

They had some kind of thing in mind when they did that - it's so intentional it HAS to be intentional - it also makes me say messing with the dry hull support system the factory devised is not a problem - I'm confident the hull is strong enough to take any support structure you can dream up because it seems to already be set up for the worst possible support structure - namely all the weight on ONE SPOT!. I know that Roger had a particular peeve about trailer boats that required you to turn your car into a submarine to launch the boat. And i must admit, I have NEVER seen a boat that sits as low slung on it's trailer at the MAC M boat does:



And when you look at the trailer it appears all the weight of the boat is on one spot. There are only three supports on the trailer - so that means there is not a lot of weight on the front and rear bunks - all the weight is on that middle bunk that sits on the axle. The front and rear bunks are really just to keep the boat balanced on that center bunk!! Have you ever seen such a thing??



It's really quite astounding - one would think the hull would need better support than just a single bunk going from port to starboard right at the balancing point in the middle (the middle of the weight balance). No other boat I know could take that kind of abusive support - if I did this on any of my previous boats it would have dented the boat or even broke it in halve. It's a very strange trailer set up. All my other boats needed bunk supports that go along the bottom of the hull from forward to aft.

Tomfoolery- glad you mentioned that your trailer is submerged during launch/retrieval. I guess it's a European thing to just get the trailer near the water and then roll the boat off the trailer. I'm sure the trailer would last longer if you only got the tires wet. I too have extended goal posts, and they are barely out of the water at my usual launch spot. I clip the winch hook in and only make a couple of turns with the winch. That guy cranked the maxus up from the next county. Different strokes.

Nice to get Boat's take on trailer vs boat hull design on the M. I've wondered whether I might go downstairs one day and see big bunk dents in my hull. The PO kept her, stick up, on the trailer at his marina, so she's been mostly on the trailer since 2013. Still looks smooth.
