Darin's Pro Boat Mystic "29 Minus-Two"

[Darin Jordan]

FINALLY got the holes drilled in the Stainless knife-blade rudder. NOT a task to be taken for granted! I destroyed a couple of Titanium bits, broke some carbides, and generally floundered, until I finally was able to get through this stuff by slowly drilling with come carbide centering drills. Lube well!

I also decided to do something I've wanted to do for a while on these boats... I trimmed away a bunch of the extra height on the wood interior. Not a big fan of the wood inside in the first place (I actually lobbied for a colored carbon looking glass or otherwise something that looked more like a pan-car chassis for inside there).

Trimming this away takes away a tiny bit of weight, but, more importantly, makes it easier to get batteries in and out and makes it easier to route the battery wires, etc. Cleans it up a bit, I think.

I do not know if you use my tips, But hear is a good one on drilling stainless steel. I do it all the time. Always use the slowest speed you can on the motor set up, Make sure the drill bit is sharp. If you can see the cutting edge it is dull. I always take out the crown on the heel. Do not push hard on the bit. Freeze the tip with a aerosol can like WD-40 offten or at the start of a crunching noise. Try to keep the heat as low as possible on the SS, It hardens with heat and becomes impossible to drill the hole.

..or get a a better bit: DRILL

Can't see that skeg strut in that pic. C'mon Darin, show us the skeg!

Geat information, I will try this out in the future. I really like the idea of transferring the
load off the motor and onto the strut. I wonder why this isn't a more widely used
setup?

I tried a skeg'd strut on my Miss G when I ran it at the 2012 Nats in P-Ltd Cat and Offshore. By the time I got the boat dialed in, only about 1/8" of the skeg was left (I trimmed it down a bit at a time).

The boat REALLY turns well, but scrubs sooooooo much speed with even the slightest turn of the rudder that it simply wasn't worth it. I have NEVER had an issue making one of these cats turn. I'm usually pretty surprised to hear that others do. These boats turn HARD. I think it's a matter of driving technique. You have to drive them sort of like a tunnel as far as approaching the turn-in... After that, throttle on and go.

Better yet... "pivot turn" them.... I aim right for the buoy, and then just make an almost square corner. Works well.... right up until you grab an outside sponson and barrel roll it...

Hi ,Darin

Thanks, I cut the transom and strut closer to the transom / sponsor is more stable catamaran

Well... after establishing the initial NAMBA N2-Cat SAW record with this boat (65.XXmph) last November, I went out for another attempt and, due to what we found out was a flaw in a Beta release of the ESC Firmware (had just updated everything prior to the weekend), the ESC burned up and took the boat out for the weekend.

I was going to just shelve it, but decided that maybe I'll try to do some resurrecting.

After some time with some Denatured Alcohol, it's actually cleaning up pretty well. The burn was so bad that the "brown/black goo" actually leaked out of the nose of the hull, out a crack in the deck to tunnel area.

Not going to be able to get this entirely cleaned up, but I think I can get it pretty good with a little more time.

Here are the results thus far...

Well, I'm known as Mr.Kapow here in Canada so don't feel too bad Darin. Looks nice and clean now! Tooth brush helps.

May I ask what brand of esc it was?

[Shooter]

Oh No!!! Sorry to hear about the 'electrical event'.

So, apparently that 'thrust at the strut' method is working, huh? .....Sounds like you set a record with it?

I did, and the boat worked OK... For SAW use, this hull is pretty heavy and certainly not ideal, but it was FUN! I had airdams on the tunnel AND on the top of the deck to keep the nose down. Those kind of band-aides aren't the most efficient way down the course, but seeing this fly by at 65mph plus on 2S was pretty cool...

Just a fun project. I just can't leave it for the scrap heap, especially since it's not really that far gone... Just smelly...

Would it not make a nice N2 offshore hull?

It does...

It also made a nice N2-Hydro National Championship hull...
