I am cutting the hawse holes thru the bulwarks of the Bristol. It has been tough going, I have six hawse pipes and each one takes three holes, each thru 2 inches of solid teak and six layers of epoxied fiberglass. Typically a new forstner bit dulls and becomes useless after a single hole, which takes about an hour to cut. Finally I happened upon the Colt forstner bits forged in Germany. God I love German tools. I bought the needed size, about 45 dollars from Woodcraft and I am here to tell you it is amazing. It does not dull, period. It cuts thru the bulwark in perhaps 30 seconds, literally like a knife thru warm butter, Here is the write up from the Woodcraft catelog.

COLT MaxiCut is a totally new cutting head design that combines the advantages of a forstner bit with those of a boring bit while the high performance RotaStop shank provides optimum torque. Sectioned cutting rim produces less heat for considerably longer tool life. Saw tooth effect of both cutting cam pairs on the circular cutting edge offers a noticeably easier and faster boring tool. Chip breaking grooves on the internal cutting edges of 3/4" and larger bits guarantees smoother drilling and easier swarf removal. Suitable for half, inclined, overlapping and deep bore holes.Polygonal shape of the RotaStop shank ensures optimum transmission of torque and practically chucks itself automatically by means of rising contours.No slipping in the chuck and precise results when machining the hardest of materials.Combining Morse-Taper adapters and extensions allows easy tool changing within seconds and longer service life for the bits.
