23 sf trailer dimensions

[Pair a Docs]

I am new to the community so please forgive if I go about this the wrong way...still trying to figure out how things work here.

Will be starting refurb on my first SeaCraft once I get it home. 1980 23 sf outboard. I will post some pics when I figure out how to do that.

Today I need some trailer set up help. I need to know the length from bow eye to transom. I believe I saw that on a thread but can seem to find it again. 21.5' was given as the length. Can anyone confirm that?

The boat is still an hour and a half away....I'd rather not drive up there just to get this measurement.

Thanks
