Wondering about the Schock 40

[learningJ24]

Pay attention to the steering system. We sheared off the connection between the tiller head and the aft foil. FUBARed the steering system. You can limp along using the front foil by running lines from the front quadrant to the cockpit. Also, the 12/24 volt system was "interesting".

What does such an elaborate steering system buy you in performance than a standard aft rudder. It was a cool thing to see but it just seems, errrm, strange....

All of the lateral resistance was in the "rudders" rather than the "keel". The largest feel difference was when a puff came in while close reaching under a chute, you tugged the rudder and the bow went down. Foils didn't load much, they just made the boat go where you steered.

its kinda stupid - the two dagger boards with a canting keel is now the norm

it works like a jibing dagger board - the hull is allowed to rotate to a minimal angel of attack thru the water, lowering hull drag - as always, the dagger boards, or in this case rudders control side force

there is no net extra height.

That boats spent a few years on Lake Erie before going to SoCal

So are they fast?

27.8 knots fast enough?

certainly no AC72

but not bad for a 10 year old 40 monohull

That sir I cannot disagree with. Any more info specifically on Hull 6?

We were doing 22 with a reefed main and a #4 off some waves with a pretty steady 16-18kts. Then the steering system broke...

The boat had the smoothest transition from displacement to planing I've ever experienced.

I looked into buying that boat. Low 30's would buy it with a trailer which sounded like a deal to me. Being out west complicated things.

The CF rig was replaced with a taller (1M) alum rig I was told.

True, but the CBTF patent had some effect on the evolution to the current norm.

Well its coming back to the east coast... Annapolis

IIRC, the idea of fore and aft rudder similar to Blackaller's 12 metre US 61 USA aka "the geek", and the various ACCs built with twin rudder layouts (IIRC NZ20, the Swiss boat and the 2nd GBR challenge boat). was that by sharing the lateral resistance job between fore and aft rudders, you were placing the foils in the high pressure areas of the bow and stern wave. Less relevant in a light boat like the Schock 40.

The boat did/does have a "collective" control, which (again, IIRC), put a equal amount of AOA on the fore and aft foils - similar to a gybing board. Part of tacking was tacking the collective. One disadvantage of the CBTF system was that unlike daggerboards, you couldn't reduce wetted surface in the light/when you didn't need the lift.

 

[KeithMagnussen]

Yeah you need all new sails for that boat!

 

[The_Cunning_Ham]

Was it not well taken care of by its last owner?

 

[Still]

Seen a few of these cycle through Long Island Sound. Seem to be perennially disappointing, kind of like the hot/nutty actress who attracts a string of guys who come to realize that she's a nightmare to live with, no matter the potential or "benefits." Perhaps the most often resold boat of recent memory. Meanwhile, other guys buy an Express 37 and hang on to it for a decade or more.

Too bad, I liked the out of box thinking when they were new and the idea that you could sail a 40 with 5 bodies rather than 10.

That sir I cannot disagree with. Any more info specifically on Hull 6?

One big difference that I'm aware of is that hulls 1-3 have a one piece machined fin while the later hulls have a fabricated fin and pivot. Close inspection of the welds is important. I believe that Matt Brown had a close involvement with the construction of hulls 1-3. I race on hull #2.

Tough to compare most boats to expresses. They were ahead of their time and well built.

Schock 40 did the offshore series out of sf 15-20 years ago. It was a baby blue hull. They blew people away but if I recall correctly they dropped their canting keel. I thought it was a sweet boat as I was young. My dad said stick with what works. That boat won't be around for long. He proved to be correct.

 

[DryArmour]

The keels on the early models definitely had some issues as did the rudder. The boat is a blast to sail and while the aluminum rig might make her a little more tippy, the added power should make her fun for the East Coast depending on where you sail her. Minimum free board makes her a wet but really fun ride for sheltered venues without big chop. Enjoy the boat and drop me a note with any other questions.

Still - sometimes you just need to know how to handle that wild little gal in the short skirt.
