Chris! Happy to see you here, your a wealth of information and look forward to your posts. Always learn something new!

Where are you and the Hogfish at in the world Chris?

Rachel and I live now on a small island in BC Canada. She’s Canadian and I am now a permanent resident. We live ona 1/2 acre lot on Hornby island. It’s great here …Canada provides free air conditioning 24-7.

Glad to see found your way here.
How’s your current build coming along?

That’s to cool. Feels like they should be framed and hanging in a skiff museum somewhere. Thanks for sharing them with us.

That’s AWSOME!! Thank you for sharing Chris👍

Those drawings are too cool, and I agree with @MikeCockman. Frame them and display them!

Chris, is that a weight and balance draft, what do you use as your zero ref?

Where longitudinally did you want the CG of the Whipray?

Very cool, I still have my graph paper and weight balance for some of the designs in the USAF.

A collector has them framed in his office. 33 of my original designs and all their plans sheets are at the IGFA library in Ft. Lauderdale Florida where they can be seen by appointment. Another collector has 200 + sheets of my other designs in Miami. Now I don’t have to worry about them getting ruined. I have every thing on stik though so I can reference if needed.

It’s just aft of station #4 not marked. But it changes with people aboard and movement.

You can see it in bragging section. Today I finish final glassing section of the hull. Then next few days I spread fairing putty. Next week dust storm for a day with my fair contraption then long boarding chines etc. looking to have the Toadfish trolled up right this month.

@Chris_Morejohn thanks for the info, I’m sorry it’s fascinating to me!

So it looks like you designed a 36% CG from aft, is that so that the fisherman creates a bigger moment and levels out the boat with less fisherman weight and the poler creates less? Or is it to run the skiff better, and it just works out that way?

Well I am always learning new things but the CG on a plans lines drawing to me represents the center of the displacement at the given waterline. Now you put all the weight right in that section it should float level as drawn. In reality weight is spread out over the hulls skin, the engine, tabs, tower then the steering gear, where to balance these loads …. Fuel tank helps when it’s full and so on.
With people you can trim when at rest, if alone trim is more tricky when poling, so the CG to me is a starting point. A canoes could be dead center but you would look to design for your static body weight and then where gear weight can go to balance etc. small boats for me it’s numbers , feel from real life’s experience on the water and many types of designs and well art….
