I read the tag from the image at Figure 2 as follows:
BWC = the manufacturer ID Code or MIC for Boston Whaler, applied with ink, faded, and hard to read
2837 = a partial five-character production sequence number, clearly embossed
B = trailing character and part of the production sequence number (2837B), applied with ink, faded, and hard to read
M = model year format, which could be used prior to 1984, applied with ink, faded, and hard to read
80 = two digit year of production for 1980 clearly embossed
I (letter "i") = trailing character indicating month of production; I = April; clearly embossed but easily confused with the digit "1"
Please note that my reading is the same as that given by the OP, except that the last character is interpreted as a letter instead of a numeral. [The characters BWC, B, and M are difficult to read, particularly from the photo-image, because they were applied with ink and have faded. I have relied on the OP's interpretation of these characters.]
Generally for a 15-foot hull the HIN production sequence numbers were in the range as shown
on the chart mentioned in the FAQ. For a 15-foot hull the range is 1000A to 2999Z. The number assumed to be the production sequence as 2837B fits into this range.
As Phil mentions and as the FAQ explains, the particular model is not designated in the HIN, but, as I have demonstrated above, by comparing the HIN production sequence number with the chart of HIN production sequence numbers I have provided in the FAQ, you can make a reasonable inference about the hull length.
All of the inferences I have made are DIRECTLY from the explanation of the HIN number formats in the FAQ. There is nothing unstated in the FAQ that was involved in making this interpretation. One must read the FAQ carefully to become familiar with the possible formats in use.
From the distorted image in Figure 1, a reasonable inference is the boat is a 15-footer. This also correlates with the interpretation I give above for the HIN.

This first-hand observation removes all mystery: the boat is a 15-footer. This again correlates with the interpretation of the federal HIN metal tag.
A further correlation is that use of the model year format was suspended after 1984, as was the use of a metal tag attached by rivets. This further correlates well with the boat being made prior to 1984, as we have deduced from the 1980 model year format.
The month of production is clearly indicated as April, again according to the model year format for federal HIN numbers prior to 1984.
Thus the total interpretation based solely on the HIN is as follows: the boat is a 15-foot Boston Whaler boat made in April of 1984 and sold as a model year 1980 boat.

There is no particular model variation encoded in the HIN. This explains why you have not been able to deduce a particular model from the HIN number.
METHOD OF PREPARATION OF HIN TAGS
Boston Whaler used a method of preparing metal HIN tags that pre-printed the tag in ink with certain elements of the HIN. Usually the BWC prefix was done in ink, as would be a character that would be part of the production sequence that would not change rapidly, such a a prefix or suffix character. Also the M for the model year format would be pre-printed in ink.
ASIDE: From the highly distorted aspect ratio of the image at Figure 1, I infer the original image was probably take with an ultra-short focal length lens. This causes the boat's length-width ratio be appear distorted. It also causes a massive amount of extraneous foreground and background to be captured and included in the frame of the image. We are only interested in the boat, not in the yard, buildings, trees, utility poles, overhead wires, and sky that were included in the image and made up about 90-percent of the image. Those have all been cropped from the original image, and only the boat is now shown in Figure 1 as it appeared in the original image.
