Thank you, Gentlemen. Out of town now but when I get home, I am going to carefully second check/determine

1) This boats “X” and

2) Prop Shaft to keel on this 2020 Classic 22 with rounded hull.

The boat was made in June of 2019.

Just trying to establish a sound baseline of knowledge with this hull so as to make calculated changes.

I know data may show up later on this forum when a person may be doing a search for knowledge and looking for reference.
When I get back after the holidays I will double check both the 1) X on my 2020 and 2) Keel to prop shaft.

It would be nice to know keel to prop shaft on the Shelby 22 Classics as they are often referenced as working well, but I have never seen an actual number to compare.

I will offer this concept for the time being. River Dave put out a drawing to explain "X" and with a 14 degree transom angle he had a 16 1/2" "X" and a 5 3/4" keel to prop shaft "NOT TO SCALE BRAVO 1 Drawing".

Reverse engineering, using his drawing, a 17 3/4 "X" would be raising the "X" 3/4" and reducing the shaft to keel to 5" which seems to be conservative number for the "V"'s.

When I purchase a lower I do not want to have to use a spacer to adjust depth as I went a clean look.

Thanks Ed

I think you meant 17 1/4

Thanks Griff for the catch. I try to be accurate.

I remember reading yourself and Vette back in the middle 2000's and later.
