I think you may find that it is actually a Herreshoff H28. I think it is actually 29'.5.
Compass Yachts built hundreds up till 1984.
I have had a Compass boat and they were strongly built.
They the H28 have a reputation as sea kindly capable of offshore, a bit slow and tend to make more leeway with the less draft. I know of someone who did a round the world solo in one.
I very much doubt that Compass were building to 28' in the 80s so this is probably it.
