Thanks for the comments! No, I did not glass over the repaired area--(should I have done so?) The foam was injected directly into the delaminated area via a 6 inch round hole I had cut in the hull for an access port. This had exposed an easily accessible cross-section of the delamination. The hull was otherwise intact. I had read somewhere that for areas of delamination over 6 inches in diameter, the damage should be "re-foamed" at a boatyard. Since the damaging incident last summer, the area of delamination had expanded from the original 7-8 inch wide round area (starting about a foot in front of the forward pylon). It now extended from two inches in front of the forward pylon approx. 2.5-3 feet up the hull, narrowing as it went. It was 2-3 inches wider (on both sides) than the 6 inch hole I had cut for the port (that was a foot away from the forward pylon at its closest point).

If I have just managed to stop any further delamination I will be happy--I hope this will prove to be the case. I consider the extra rigidity a bonus.

I am hoping the foam lasts as long as it has where I have used it to seal conduit pipes, windows, etc. in my house--which has been over 10 years now. The foam has remained intact and slightly pliable over the years if not exposed to direct sunlight. I will make every effort to ensure that no-one steps or sits on the repaired area.

If the repair survives the pounding Atlantic surf (at Holden Beach, NC!!) in August, I will be pleased.
