When to go to Seattle
Late June through mid-September, and mean it: the dry season delivers under an inch of monthly rain, low-70s days, and the long northern daylight that makes evening water sessions possible — while November through February offers 17-plus rain days a month and 4:20 p.m. sunsets. Inside the good window, plan around Seafair (typically early August): the Blue Angels close all lanes of I-90 between Seattle and Mercer Island during show windows, hotel-row park rates spike 2-3x, and the guide's advice is to route via SR-520 (tolled) midday on show days — trailer in tow, that reroute is worth planning rather than improvising.
Where the trip actually bases in Seattle
Every place below comes from the Seattle arrival guide.
Saltwater State Park
The saltwater shoreline park 20 miles south at Des Moines: camping to 40 feet at $37 on a 9-month window, with a $10 sanitary dump, rinse, and potable water on site. For a boat-and-camp trip it is the closest state-park pairing of shoreline and utilities to the city — under the Sea-Tac approach path, as the guide honestly notes.
Washington State Ferries (oversize rules)
The sound's highways are ferries, and they price by length: WAC 468-300-040 classifies any vehicle 22 feet and over — including tow length — as oversize, with separate fare brackets. A truck-and-boat-trailer combination almost always crosses that line, and rigs exceeding height or weight limits need WSDOT's oversize form emailed three business days ahead.

U-Haul of Ballard (Leary Way)
The staging quirk the guide flags: this propane stop sits inside the SMC 11.72.070 industrial-zone exception, meaning oversize combinations can legally stage overnight on the surrounding blocks — the only free overnight category the city offers. The lot itself is narrow (under 28 feet), but the neighborhood's legal status is the real asset.
Lake Pleasant RV Park
The north-end full-hookup base in Bothell, 17 miles out: sites to 45 feet at $89 with sewer and Wi-Fi, and a dump available to non-guests by call-ahead. For a week alternating sound days and lake-country drives, it is the comfortable pivot on the right side of the metro for northbound water.

Frequently asked about boat rentals in Seattle
Do I need a license to rent a boat in Washington?
Washington requires boater education for many operators, with rules that vary by age and boat. The authoritative answer for the specific boat is on its listing: every PickRV boat states whether a licensed captain is required, which education card applies, and what safety equipment is aboard. Saltwater is unforgiving of shortcuts — read the rules line.
Can I take a rented boat trailer on a Washington ferry?
Yes, with length math: WSDOT classifies any vehicle 22 feet and over — measured including the tow — as oversize, charged by length bracket, and combinations exceeding height or weight limits need the Oversized/Overweight form filed three business days before sailing. Measure the full truck-plus-trailer rig honestly; the toll booth will.
Where does a trailered boat legally overnight in Seattle?
Outside a campground, only in the industrial zones — Ballard, Interbay, SoDo, and Georgetown — that SMC 11.72.070 exempts from the midnight-to-6-a.m. ban on vehicles over 80 inches wide, and even there the 72-hour blockface rule applies with Lincoln Towing enforcing. The lower-stress answer is a hookup park: Lake Pleasant or Trailer Inns, both with dumps.

What it costs, without the drip
Boats on PickRV list from $175 to $1250 per day across the range — and Puget Sound conditions argue for the listing's stated capability over ambition. Checkout adds one 10% service fee, with a full rental refund if you cancel at least 48 hours before pickup. Ferry fares for trailered combinations price by length bracket; staging camps run $37-89 a night.
What counts as Boats on PickRV
On-water rentals open up the part of a trip you cannot reach by road. PickRV groups boats by how you use them. Pontoons are stable, easy-to-drive platforms for families and lake days. Ski and wakeboard boats are built for towing riders behind them. Jet skis and jet boats handle rivers and quick coastal runs. Houseboats turn a week on a large reservoir, like Lake Powell, into floating lodging. We organize boats by state and by water — coastal launch points and named lakes — with the local marina and the governing agency for each. One important rule: captain-license and boater-education requirements vary by state, and some rentals require a licensed captain on board. Each listing states the rule clearly, plus the included safety equipment. Renters pay one transparent 10% service fee at checkout, with no drip pricing, and a cancellation at least 48 hours before pickup returns the rental charges in full.
