Fire damage to my bowsprit!
Teak makes a ppretty poor material for a bowsprit because of its weight and unreliable strength. Teak glues up very poorly and so laminating a section out of teak is a less than perfect idea. I believe that the current thinking on laminating teak suggests using resorcinol glues. Resorcinol needs perfectly mated surfaces and a lot of pressure to establish a proper glue line.
There are companies that import balks of Teak. Conglin in Brooklyn used. I would look at a copy of WoodenBoat magazine. While not as rot resistant you can also try to find balks of Angelique and Ipe which have teak like qualities but less than Teak prices. More traditional bowsprit materials are clear fir, hickory, ash, or oak in that order.
Sorry about your loss.
