you should mention them - I just ordered from them a number of Buck-Algonquin hawse holes.
I ordered four of the cleated versions and four non-cleated in the same size to form the inside and outside of the fore and aft hawse holes. I'll have to completely glass in the existing holes, as the throats of the replacements
still aren't deep enough to meet. For the two mid-ship hawse holes, I ordered four of the smaller non-cleated versions. B-A's mated hawse holes weren't deep enough for that application, plus the flange dimensions were a bit too large to fit the space between the caprail and the deck
I checked a few existing powerboats here in the marina, and even though they're new, they mostly seem to have the same problem: the bulwarks are too thick. The only hawse holes I see which extend all the way through are obviously custom jobs.
I'll try to post some construction pictures on my website when I finish the work.
