About Grand Adventure

Statement from the current owners:

This boat is reliable and has amazing seakeeping ability. After a shakedown cruise in Puget Sound our first summer, we outfitted her to be able to cruise to SE Alaska via the inside passage. Along the way to Alaska, we found we were well equipped to navigate in extremely foggy conditions, admirably handle rough seas (she took 12 foot waves in the Dixon Entrance and did great), fished, crabbed, hiked, and explored in our dinghy. Grand Adventure's 2 x 500 hp engines and top speed of 22 knots allowed us to comfortably navigate strong currents in narrow channels in B.C. and Alaska, where cruisers might expect to encounter currents up to 6.5 knots, such as when we headed north through Dodd Narrows, B.C. near Nanaimo.

The enclosed flybridge kept us warm and dry during the chilly cruising to Alaska and allows for an extended PNW cruising season – unzips to let in fresh air as needed! Our 2020 plans were disrupted by the pandemic as we were planning on cruising to Haida Gwai via the inside passage, then transiting south around the very challenging west side of Vancouver Island. Instead, we cruised 1,100 nautical miles from the South Sound and in and around the San Juan Islands, the Hood Canal, and through the Ballard Locks to Lake Washington. We appreciated our shallow draft (3'10") that gave us the confidence to enter shallow bays and inlets such as Hammersly Inlet heading to Shelton, WA, in the South Sound this summer.

Not only is Grand Adventure a highly capable, reliable cruising vessel, she has beautiful, classic lines and lots of room to spread out. As a cruising couple, we found that we had plenty of room for all our supplies with room left over. But we were also able to host 18 members of our yacht club for happy hour while at anchor in the San Juan Islands and everybody had room to relax and be comfortable inside and out.
