We just went through the same process as we're planning on having our 29, Circle T, in the PNW from June through mid-October. We live and keep our boat in Los Angeles, but want to experience the PNW this cruising season. We made a trip to Seattle to check everything out, and chose Cap Sante in the end. Here's why:
1. There is scheduled bus service from SeaTac airport to Anacortes 11 times per day. Drop off point is the Shell station at 14th and Commercial, which is just a short walk to the marina. We don't want to deal with a car. For information see
http://www.airporter.com (By the way, the bus also goes on from Cap Sante to Skyline Marina farther west, and closer to the San Juans. But the next 2 items sold us on Cap Sante.)
2. The marina office is within several hundred yards of a Safeway food store, a hardware store, and a West Marine store. Again, we don't want a car there.
3. The town of Anacortes is terrific!! (The Majestic Hotel has a Happy Hour everyday from 4-6pm where the gourmet food is unbelievable - and every item is $5.)
4. The location of the marina is close to the San Juans and does not require timing your trip thru Deception Pass with the tides. But it is also quite doable to tour the southern Puget Sound area from Anacortes.
5. The marina is planning to undergo construction, which means that they'll be moving the permanent boats off of E and F docks to a new location starting in early June and would love to be able to rent those slips out to people like us until the last day of September, when we'll be kicked out. So we're planning on starting our last boat cruise out of Cap Sante at the end of September, and when that trip's over in early/mid October, we'll put the boat back on the trailer probably in Seattle for return to LA. (We don't have - or want - a truck or a trailer, but are hiring Cory Gracey to do our hauling for us.)
6. The rate for E and F dock, which are 40' slips, is $370.43 This is cheaper than we pay for a 30' slip in LA... I can't tell you if other docks would be available for your 27, and I don't know the over hang allowed. I believe you can find the rate sheet online at their website.
7. The phone number of Cap Sante Boat Haven is 360-293-0694. They won't reserve a slip ahead of time for more than 2 weeks. Hopefully there'll be plenty of room for us both -- with the construction it sounded like there would be.
8. By the way, the marina itself was clean and appeared to be well maintained. The town also has every type of boat service we may need available.
We'll look forward to seeing you there!
Good luck with your decision. Hope this helps.
