Gotta love these Posts. Is there a tell-tale among the various models which gives a visual clue to what model they are? For example, seeing a similar vintage year 43 and 46, they have single vents whereas many 50s, have 2 sets of vents along the hull. Can you easily distinguish a 43 from a 46 from some distance away...or even up close? Just some curious fun... Thanks.
Not specific to Posts vents are one tell tale, side windows and portholes another , but when you're talking 3' you could be talking about the same hull just one year counting a pulpit or swim platform and the next not.
