Legend - seat post sizes

I was told recently by another Legend owner that he had purchased a few other brands of seat posts and none of them fit his post sockets correctly, he said he was told that Legend’s seat posts are a little different than “standard” diameter,

I’m skeptical of this but thought I would post here to see if anyone else has added seats to their Legend boat - better than me running around trying different brands

I assumed that they were all 2-3/8" both my Sylvan and my Starcraft had.

Mine has 2 3/8" swivl-eze posts

Unless they come from China, then they'd possibly be metric.
