Finally, someone agrees with me. LOL

We've had discussions here of how to verify air draft but never water draft. We actually do it much the same way which all starts with some initial measurements. We start with measurements from the lowest level, whether prop or keel or rudder to the bottom of the hull at the stern to the top of the transom to the top of the flybridge to the top of the electronics, etc. Let's say you've identified that the bottom of the hull at the stern is 5' above the lowest point, if you see that that point is 4" below the water surface then your draft at that moment is 5'4". Similarly if your transom top was 4' above the bottom of the hull and you measured the distance from the water to it and it was 3'6" then you'd know that your draft was 5'6". Our builders provided these measurements but we checked them. They don't change but water draft and air draft sure do.
|
Good point. I haven't checked. My builder gives the draft as 4'6". I assume this is fully loaded with water and fuel. However, I could be wrong. However, when I think of my draft, I round up. If I am in 5' of water I am just waiting to hit something. Not to mention the effect of a swell or a wake.

My AT34 is reported to have a 2.5 draft, 1/2 filled water tank and 1/2 filled fuel tanks. I have a placard indicating 5ft. If it aint 5 feet, totally full tanks and all my still I am betting it is 5ft than 2.5. LOL
Once I get to 5ft of water, I can sneak up on the bottom.

Why don't y'all just wait until you run aground and then look at your sounder. That will tell you how it is set!

Good news...it’s just bent props. BOTH props bent. No other damage. They pulled off the props and the prop guy took them to his shop to repair them.
We have a brand new starboard prop in Cape Coral waiting to be shipped to us.
David said assuming they CAN be fixed then we will come home on those props and them he will get a new prop for the port side and keep the old ones as spares.

I suspect they will fix them better than new provided you get them tuned to a high standards.
If you buy new props, still get them turned right up to the top. You run your engines at high RPM not like a true, slow turning, naturally aspirated trawler engine.

You would be surprised what they can repair. I have reworked my same props 3 times in the past 5 years. Once they looked like tacos!

Buy a spare set of props. That way you will never need them. I know....

Ouch. Do you think they will have you back in the water by the weekend. Right now weather looks good for a crossing. But we know how that can change.

I don’t think they gave David a timeframe. I believe he’s going to touch base with them today when he has some time. He’s at a conference in Virginia and won’t be home until Friday night. We probably won’t be able to go back until the 29th. Praying there’s a good weather window then.

Call general propeller in Bradenton and have them give you an evaluation. I’ve seen them work miracles. That starboard prop looks like it has some pitting near the hub you might want to have addressed as well.

Have them NDT and turned to state 3 or 4. My AT34 is turned to stage 3.
Better fuel economy and speed, supposedly
