The boat seemed relatively stable on the port tack so I chose to continue on the outside of the bay. Returning back into the main channel would have forced me to make several tacks to get back. I dropped the foil to give some lateral resistance. The added drag was causing very high forces on the rudder so I reefed the sail to reduce them. The combination of reefing and using the foil reduced my speed to 4-5 knots. I was surprised that I could still point fairly high into the wind but I could not tell how much I was sideslipping.
The distance outside the bay is 3.5 nm and I had gone 1 nm when the daggerboard broke. It took me ½ hour before I turned into the Sampan Channel and I was ⅓ nm downwind of the mark I was originally aiming at. The trip back through the channel was uneventful. Once I made the turn into the channel I was able to retract the foil and make better time. When I exited the channel and turned upwind for the beach I was close to the markers and could tell that I was crabbing badly. I dropped my foil and was able to make it to Kokokahi without tacking, landing at 1 pm.
