We rented a sailboat for a day and night from the Bellingham harbor. For 4 people it cost $125/person. It was definitely worth the money, what a great experience! We got there around 6pm and stayed the night in the harbor on the sailboat.
The boat was beautiful, 31' long and gorgeous wood on the inside. Our boat slept 7 people, but there was only 4 of us, so we had plenty of room.
We took off about 9am and motored out to Inati Bay since there was no wind to sail with. As soon as we got to the bay and anchored the wind picked up so it was a wonderful afternoon for sailing.
Inati Bay was beautiful, only accessible by boat so it had lots of walking trails and trees. We saw a seal on the way out to the bay and starfishes along the shore on the bay.
We spent most of the time on the boat, just relaxing. It was wonderful.
I definitely recommend going sailing in Washington and I will definitely do it again sometime.
