The short answer: A flybridge sedan or displacement trawler around 40 feet and above can offer the space buyers want for weekends aboard in San Diego. But a “floating condo” is still a vessel: confirm berth permission, systems condition, operating costs and safe cruising suitability before buying. Overnight visits and living aboard are not the same thing.
Sometimes a hotel room on land just will not cut it. If your goal is a comfortable boat condo on the water, start with how you will use the boat—not simply how many square feet fit inside it.
Flybridge sedan versus displacement trawler
Flybridge sedan: living space and an elevated helm
A flybridge sedan can combine a salon, cockpit and separate sleeping spaces with an upper helm. Individual models differ considerably in speed, fuel use and accommodation. Inspect the stairs, sight lines and weather protection as carefully as the galley.
Displacement trawler: a different cruising pace
A displacement trawler may suit buyers who enjoy slower cruising and longer periods aboard. Hull form, loading, engine installation and condition determine the real performance; the word “trawler” does not guarantee low operating costs or offshore capability.
Some boats in either category have multiple staterooms, a full galley, generator and generous tankage. Others do not. Confirm the equipment and capacities on the actual boat rather than assuming they come with the length.
Can you live aboard a boat in San Diego?
Do not assume that buying a yacht or renting a slip allows full-time residence. Ask the marina or dock authority about liveaboard eligibility, permits, occupancy limits, waitlists and overnight guest rules before committing. A waterfront home’s dock rights can also restrict vessel use.
Read our San Diego and Mission Bay liveaboard guide, then confirm the current rules directly with the operator. A weekend retreat and a permanent home require different due diligence.
Will a 40-foot-plus boat fit your berth and route?
- Slip sizing: Use actual length overall, beam and draft, including platforms and projecting hardware. Obtain written berth approval for the boat.
- Docking: Consider windage, access, turning room and whether you can handle the boat with your usual crew.
- Bridge clearance: Measure air draft to the highest fixed or raised equipment. For Mission Bay routes involving bridges, check current official chart information, tide level and local conditions with a safety margin. There is no single blanket “under 26 feet” rule in this guide.
- Depth: Check the approach and berth at low water, not just during the showing.
- Trip suitability: A roomy salon is not proof that a boat is ready for Catalina, Mexico or other offshore passages. Review condition, range, weather, crew capability and required documentation.
The comfort systems that can change the budget
Space is only half the story. Before buying, inspect shore-power connections, batteries, charging, freshwater pumps, hot water, heads, holding tanks, refrigeration and any heating or air conditioning. Test the generator under appropriate load if fitted, and ask for service records and independent inspection.
Budget for berth rent, insurance, routine cleaning, haul-outs, propulsion service and unexpected repairs—not just the purchase price. Our 40–55-foot yacht ownership cost guide provides a planning framework; obtain current quotes for your vessel and berth.
Does buying a Cays home eliminate docking costs?
A home with suitable dock access may replace a separate marina rental, but it is not a fee-free loophole. Dock maintenance, association dues or assessments, insurance and vessel care may still apply. Confirm exactly what transfers and whether the boat fits.

A practical next step
Write down your usual crew size, overnight needs, preferred cruising pace, berth dimensions and annual ownership budget. Then compare current yacht listings and ask Coronado Yacht Sales to help evaluate the trade-offs. If day trips matter more than sleeping space, our low-maintenance outboard guide is a useful alternative.
Brokerage reality check: This is general guidance, not legal, tax or navigation advice. California vessel purchase taxes and annual assessments are separate issues; check the [1] CDTFA vessel tax guide for purchase-tax guidance. Use qualified surveyors, current navigation information and the applicable berth rules before purchase or departure.
