Well, having a bow-eye on my DS II and having had one on our old CAL 21, I must say that it is a great thing to have if adequately backed up for strength!
The bow eye on our CAL was just above the waterline, which made it a great place to attach a "back-up" mooring pendant in a storm situation. That placed the line low and reduced the angle of pull.
For that purpose, a bow-eye is a good idea.
For towing.......well, not so much... if the eye is re-enforced (that is the area of the bow around it) it could make a good spot to attach a towline, however..... it is difficult to attach a towline that low (probably impossible from yout decl level!) and it will really be had to un hook that towline until safely docked in a calm harbor.
If you needed to be towed, a better option is to run two lines in a bridle setup, down each side deck to the jib winches. The lines should be fastened to the bow cleats to keep them centered at the bow. On a boat with a KEEL_STEPPED mast, the towline could be tied around the mast, but DO NOT do that on a boat with a DECK stepped mast. Doing that on a deck stepped mast could easily dislodge the mast from it's step causing more damage.
For most towing events, a bridle between the two bow cleats (or running through both chocks and back to a single (WELL secured, with backing plate) cleat on the deck, will work fine. A well-trained towboat operator will be able to safely tow your boat under usual conditions and adjust technique if the weather worsens.
In some cases, the USCG will use a "Kicker Hook" that attaches to the disabled vessel's bow-eye. In the USCGAUX we rarely if ever tow that way due to safety concerns while attaching/detaching that hook.
