Testing Testing

Our company (family) had the opportunity to take a long road trip up to the coast of Maine.  My goal was to test out our newly finished carbon board.  We took both the all glass Sea State 12 Sup and the Carbon 12 Sup.
On the trip, we stopped to visit family in central Pennsylvania and we took a 8 mile float trip on Bald Eagle creek.  This is a scenic tributary to the Susquehanna river.
The creek is very shallow in places.  Sups often have troubles with shallow rivers because of the fin.
Fin boxes or the fin themselves will break.  Also when a fin touches bottom, it is very likely you will tumble.
Our boards worked unbelievably well in this environment!  Our board is a hybrid of a displacement hull form but with rocker.
It might look a little odd to some but it has several advantages.
Upon approaching shallows, the rider gets on his or her knees toward the front of the pad.  This kants the board forward on its rocker profile.  The bow now sits in good trim and the back of the board is lifted about 3 or 4 inches out of the water.  It also pivots the attack of the fin so that when it hits any rocks it rolls over them.
It helps that our fin boxes are laminated in with a strong lamination of carbon fiber.
In the following video you will see this design feature in action.
Both boards are fitted with rigid 9 inch fins.  Not short rubber fins.  In the standing position, they provide great directional control.

They are on our new carbon 12 footer having fun.

Shark gets a fin

Here is the new 9inch fin we just installed on our carbon board.


We finished our first carbon fiber 12 foot Sea State board today.
It is actually half carbon.  The hull is carbon and epoxy and the deck is gel-coated glass set in resin.
A carbon finished deck would be too hot to deal with.
To wrap things up with this board, we added a 9 inch fin.  Here are photos that show how a standard fin box accepts a fin.

Our fin boxes are laminated into the hull and we find and cut them open after the hull is molded.  Once it is cleaned up, the fin attached easily...

The new fin, fin bolt and regular screw driver sit next to the just opened fin box.

This is how the bolt slides into the channel.

Next, the fin slides into the channel toward the front of the box.
You tap the fin forward with the palm of your hand or a rubber mallet.

Next, the bolt screws into the pre-inserted nut and voila, it is done.

Old boat in a barn

I've heard of great barn finds of cars, but here in Missouri you never see this:
A 1929 Square Meter class Skarry.  It is a beautiful mahogany racer from Sweden.
Here is the Wiki link:

Check it...




The owner called because he is interested in a restoration.
Sweet!

The new Sea State 12 SUP is here

We took our new SUP out for a paddle this weekend and had a great christening.
Here are photos from our paddle around Horseshoe lake.
This first board is an all glass hollow board with carbon fiber internal supports.

It  is 12 feet long and 31.75 inches wide x 5.5 inches.
It is strong and rigid, also light for its size at 35 pounds.  Christa here is barely pressing it into the water with her pretty 110 pounds.  This board can easily handle riders in the 250 pound range.




Here I am paddling among the rushes.  My 190 pounds are getting the board into proper trim.




Here is a photo of the watertight deck compartment.
Great for storing the essentials (keys and phone).
Tie downs on the stern are great for securing anything else.

Hull #2 is carbon fiber

This was fun and scary.
Four yards of expensive CF cloth.  It came out great and is super light.
Here are photos of the second hull out of our 12 foot mold:

SUP: inner supports for the deck

We prepped the halves of the board for bonding and will put it together in the morning.
The deck has a gel coat finish and is a laminate of glass cloth set in epoxy.
It has bulking supports bonded in and these rest on carbon fiber tubes we make.

Here is a photo of the CF tubes bonded to the hull.  They are ready for the deck.


Here is the deck:

We pulled off a great looking SUP hull

The first part out of the mold looks glossy and fair.
This is a 12 foot long SUP.
We made this part out of layers of 8 oz twill glass cloth.
It has reinforcement on the centerline and at the shear.

We will prep the mold for hull number 2 right away.

Here are photos:

The glass edge will of course be trimmed prior to fitting the deck.



SUP: First hull

We prepped the hull mold Thursday, sprayed in white gel coat Friday morning and glassed the board last night and this morning.

We hope to pull this first hull out of the mold this evening.
The next step is to finish polishing the deck mold.

We plan on making the first deck Sunday June 1st!

Heating up in the sun.

The fin box is bonded in.

Outboard impeller replacement

After you remove this grommet, you can unfasten the transmission linkage.
Our Mariner 5 hp was taken in on a trade last year.  It was spitting plenty of water so we used it for the season but now is the time to replace the impeller.  It is way better to replace it too early that too late.

We ordered the impeller, 2 extra shear pins and a cotter pin from Boats.net.
Here are photos and descriptions of the process:


Here we are removing the prop and unbolting the lower unit.

Here we are removing the impeller housing.
Here is the worn impeller.  Two fins were cracked
so we got it in the nick if time.
If it disintegrates while running, pieces can get lodged in passageways.


Here is the drive shaft assembly.
It is unrelated to the impeller, we just wanted to see it's condition.
Looks good.

This is the new shear pin.  The grooves make for weak spots that will fail if you hit a stump.
This can save the prop.  If you have pliers with you and a spare shear pin, you can keep boating.

Back in business!




SUP deck mold

We stripped the mold off the plug.
This afternoon we trimmed the rough edge and sanded it as well.
The mold looks great.  We will go over it with 1500 grit paper wet then re buff to get rid of the PVA texture.
We added a stringer in the mold on the centerline, but since the profile is thin it still has some flex in it.  We will place the mold back on top of the hull mold and add a rigid frame to it.
Here are some photos of the deck mold:

Deck Mold: glass work

We added the layers of glass to the gel coated mold.
After the resin cured to the touch, we moved the whole shebang out to the mid-day sun.
UV light really speeds up the hard curing of resin.
We plan on stripping the mold off the deck plug tonight.

Curing with Mr. Sun.  The edge of the mold will get cut and sanded so it has a nice edge.

This photo shows the two half molds together.
The board will float in this trim, but 3 or 4 inches lower.
