Hickman Sea Sled Information

Just glue some on and see.

If you like the results, make them permanent.

( Not sure if doing this on a single when twins are on the way is prudent. )

 

So, did you pick up your phone, started the Phyphox app and measured the actual accelerations that limited your speed then?

 

I am ashamed.

No. Anne said "this is getting uncomfortable"

 

The chines are designed to let the stern slide sideways. That is there purpose.

The Boston Whaler is a wretched piece of jetsam compared to the sea sled Raymond Hunt ripped off. The whallower had a third keel, losing the sea sled advantage, while incorporating its disadvantages.

I have 60 year old carpenter eyes. Better than a clinometer at sea, at such accuracies.

 

Yes, the slight V aft should provide better lateral resistance.

No, the floaty feeling seems like it is a predecessor of uncommanded maneuvers.

 

Ohhhh, like the Boston Whaler when overpowered.
Ask me how I know...

I suspect you're feeling the floatiness of a sea sled at speed.
Does it maintain direction or does it start to wonder?

Get the app for your phone and collect some real data!
Your reports are too subjective.
How does your friend John like driving it at speed?
Did he feel uncomfortable?
Perhaps you just need to get it up to 40+ knots and measure your 3-D g-forces there.
It may return to the rails you seem to like at those speeds, you don't know.
It's all so touchy-feely, kumbaya.

Carry-on

 

Ok.

 

Good boy, now you can even calibrate your 60-y built-in inclinometer!

 

Lol!

I checked it with my angle finder just now. Top edge of portside window frame against horizon. 1.25°

 

Somewhere you mentioned the vertical angular difference between the centerline and the keels, but I can't recall. Please enlighten me again!

 

The steepest angle occurs at 27% LOA, 21°
The tunnel apex then becomes tangent to a line at a 3° angle to the transom, as viewed in profile.
