The evolution of the 38 DW Fury

[Sean H]

Stretched acrylic is obtained by stretching as-cast acrylic sheets, a process which reorientates the long polymer chains. This drastically increases the material properties.
Stretched acrylic has an improved craze resistance as well as a far better stress, crack propagation and solvent resistance than as-cast acrylic. It is therefore suitable for birdproof windshields, canopies, outer cabin window panes and other transparencies for pressurized aircraft.

Thick strectched acrylic windscreens, small openings, big flanges, no fasteners, flush masks (no seams).

Yep, we are all pretty anxious now... :leaving:

Have you ever heard the saying "Fake it till you make it" ??:sifone:

Good work Sean I still can't believe it.

 

[Rik]

Well, yes, its the first 38 race hull, Dales is the first version of this hull, but is drastically different with a shorter running surface and the rudder obviously.

It will be stretched acrylic again from Triumph.

Dale's has a shorter running surface? Triumph is Jim Lee correct?

hea sean, after reading WPPA's new canopy rules acrylic is not allowed, only ploycarbonate ??

how come it seems the US guys are running acrylic then?

 

[Ryan Beckley]

Skater's race windows are all polycarbonate.

 

[skaterdave]

Skater's race windows are all polycarbonate.

looks like DW, mystic are acrylic ?

 

[Sean H]

Skater's race windows are all polycarbonate.

and those are the ones that I have seen fail over the last couple seasons, I will take the much thicker stretched acrylic, (and possibly more importantly, installed properly) but like you said on the other thread, all a team can do is make their own best decision.

Very cool Sean. Thanks for sharing the evolution of the Fury 38' DW with us.

The "crash" bulkheads go in next, the new cockpit liner is structural, so we will have a cockpit within a cockpit. There will be NO penetrations (or hatch access) through these bulkheads.

 

[Heatwave]

When the canopy is laid up an integral carbon roll cage (like this one) will be built in.

 

[Heatwave]

Do we go a step further and add two moly roll cages?

who's boat ?

 

[Ryan Beckley]

COPELAND'S, I think???

 

[Ryan Beckley]

Guy your layout looks great....BULLET PROOF!

 

[skaterdave]

heatwave, you guys ever think of foam filling the voids created by the "deflector-bulkheads" ?

 

[BradH]

How far aft was the canopy moved?

 

[BradH]

Are you making the changes to the bottom?

Do you have a weight and CG estimate Sean?

 

[Sean H]

The bottom is staying the same, the canopy is coming back about 30 inches (also going from 4 person to 2 person). The CG should stay around 105 but with a more focused weight around that CG with the elimination of the ext. boxes and moving the engines forward (they were moved rearward to test this CG placement).
