Hi Guys

I have a 1987 40 ft Hunter Legend is there a way to tell by the hull number
what keel it has being the deep draft of 6.5 ft or the shoal draft of 5.0 ft
Thanks Rick

A measuring tape may be the easiest way

Any reason you can’t do that?

Or run up on a beach and check the depth gauge when keel hits the ground?

How long have you owned this boat?

Sorry Rick.

No, details like that are not contained in the hull number.

Visual inspection is the surest way of resolving the query.
In the water is wet and cold. In the slings is easier and likely more accurate. There is a cost either way.

I would run it onto a rock. The problem with a Sandy beach is that you’ll bury the keel a bit, and your measurement won’t be accurate .

I had a 40.5 with a wing keel.
If I ran it aground in the 1000 islands, the first thing I would do is make lunch, as you’d be there for awhile,

You could drag a line under the keel, pull it tight, and mark where the line meets the deck. Then pull the line out. Holding the two marks together stretching the line to find the mid-point. measure from the mark to the mid-point. That is the angled part of the triangle. Go to this website Right Triangle Calculator | Find a, b, c, and Angle and enter the result for the letter C. The other number you need is the boat width where you marked the line. Now take the measure made across the beam divide it in half and enter it on the website as A. As soon as you enter the number the calculator will give you the B length. The last step is to subtract the distance from the water to the spot where the line was when you marked the line with it under the keel. Although this may not give you an accurate number it should be close enough to decide which keel you have. Keep in mind that the line measurement will not be perfect because it has to curve around the hull so it will not extend to the bottom of the keel in a straight line and it will also have to go around the bottom of the keel. This will cause the measurement to be slightly off, but it should be close enough to determine which keel is on the boat.

Another way would be to use some sort of straight edge (something that does not float) longer than the width of the beam of the boat with a marked line on each end of the straight edge with the two keel depths that you have to choose from. You could then pass the straight edge under the keel then lift the straight edge up until it contacts the bottom of the keel. Then align the marks on both sides of the boat to the level of the water to see which of the two marks are closer to the water level. You should be able to determine based on the marks which keel you have.
