Repair & maintenance guides

Sailboat Spring Commissioning: Rig, Sails, Bottom, Engine and First Sail

A sailboat-specific spring checklist: inspect the rig before it goes up, bend on the sails, check through-hulls and the bottom, recommission the diesel or saildrive, bring the head and freshwater back, test electronics and safety gear, and shake it all down on a first sail. Each system links to its detailed BoatMend guide.

Sailboat Wheel Steering Cables and Conduit - Service, Tension and Replacement

Keep a sailboat's wheel steering from failing: lubricate the chain, bearings and cables with what the maker specifies, set cable tension, check sheaves, idlers and conduit for wear and chafe, and replace worn cables or conduit before they part. Includes a dockside emergency tiller check.

Salt and Scale in Raw-Water Cooling: Flushing Habits, Descaling and When It's a Shop Job

Learn how salt and scale slowly narrow your engine's cooling passages, how to spot the warning signs (a temperature that creeps up over seasons, a weak telltale, thermostats sticking), the flushing habits that prevent it, which descaling products and methods engine makers accept, what never to pour through an engine, and when to hand the job to a shop.

Salvage and Branded Title Boats: What They Mean, the Risks, and How to Check Before You Buy

Understand boats that an insurer declared a total loss: what salvage, rebuilt and hull-damaged title brands mean, why flood and storm boats hide expensive problems, how branded titles affect insurance, financing and resale, how to dig into a boat's history, and what a survey should check. Title branding rules differ a lot by state, and some states don't brand boat titles at all.

An owner's guide to putting Starlink aboard: which plans allow coastal, offshore and in-motion use (as of October 2026), how much battery it eats, 12-volt versus inverter power, where to mount the dish, and how to route and seal the cable without leaks.

Satellite Messenger vs PLB vs EPIRB: Which Emergency Device Should You Carry?

A PLB or EPIRB calls government search and rescue through the 406 MHz Cospas-Sarsat satellites with no subscription; a satellite messenger like an inReach or SPOT sends an SOS through a private network and adds texting and tracking for a monthly or yearly fee. Learn how each one alerts rescuers, what registration, subscriptions and batteries they need, what to carry for lakes, coastal and offshore boating, and how to test without causing a false alarm.

Seasickness: How to Prevent It and Care for Seasick Crew and Guests

Almost anyone can get seasick in the right conditions, but a few habits make a big difference. Learn why it happens, where to sit, what to eat and drink, how over-the-counter remedies fit in (and why the person running the boat must be careful with drowsy ones), how to look after someone who's sick, and when it might be something more serious. General information only, not medical advice.

Selling Your Boat: Broker, Private Sale, Consignment or Dealer Trade-In

Shallow-Water Anchor Care: Power-Pole, Minn Kota Talon and Raptor Maintenance and Troubleshooting

Keep a shallow-water anchor deploying and holding: rinse it the way its maker recommends, inspect the spike and pivot bolts, check hydraulic fluid on pump models, keep the fuse, wiring and pump dry, update the software, know how to stow it by hand and get it ready for winter. Internal pump, circuit board and cylinder repairs go to an authorized service center.

Sharing a Boat: Co-Ownership Agreements, Partnerships and Boat Club Alternatives

How to share a boat without losing a friend: choosing a partner, what a written agreement should cover (shares, costs, scheduling, maintenance standards, insurance, title, decisions and the exit), how to handle the inevitable disagreements, and when a boat club, rental or peer-to-peer option makes more sense. Practical guidance, not legal or tax advice.

Shipping a Boat with a Professional Transporter: Quotes, Vetting, Prep and Claims

Most boat shipments go fine, but when they don't, the owner who checked the carrier's authority and insurance, prepped the boat properly and documented everything at pickup and delivery is the one who gets paid. Here's how to hire a transporter, prepare the boat and handle damage.

Shock-Absorbing Boat Seats and Pedestals: Choosing, Installing and Adjusting

Pounding through chop hurts backs and necks, and hard wave impacts can fracture a spine, especially up front. Learn the difference between a shock-absorbing pedestal and a suspension seat base, how to mount one solidly, how to set it for the rider's weight, and the simple care that keeps it working, plus the seating and driving habits that matter just as much.

Shore Power Adapters and Y-Splitters: When a 30A or 50A Adapter Is Safe, and When It Isn't

Pigtail adapters and Y-splitters let a boat plug into a pedestal that doesn't match its inlet, but the wrong one, or the right one used carelessly, can overheat, trip the marina's ground-fault protection or start a fire. Learn the difference between 30A 125V, 50A 125V and 50A 125/250V, which adapters are reasonable, how to keep loads safe, and how to check connections for heat.

Shore Power Cord Ends: How to Judge a Cord, and When to Replace the Plug or the Whole Cord

Burned blades, a hot plug or a cracked locking ring don't always mean a brand-new cord, but sometimes they do. Learn how to inspect a shore power cord and its ends, decide between a replacement end and a new cord, what a proper sealed marine connector looks like, which parts of the job are safe for an owner and when the work belongs to an ABYC-certified electrician, plus the habits that make cord ends last.

Shore Power Inlet and Cord Upgrades: Burned Plugs, Better Connectors and Safe Adapters

Why shore power plugs and boat inlets overheat and burn, how to spot an inlet that needs replacing, what newer connector designs offer, and how to choose, size and care for cords and adapters.

Single-Line Reefing: Converting Slab Reefing and Leading Reef Lines to the Cockpit

Decide between two-line and single-line reefing, plan the blocks, clutches and line lengths, keep friction low enough that one person can actually pull the reef in, and test the new setup at the dock before you need it in a blow.

Smoke and Heat Detectors on a Boat: Where They Make Sense, What to Buy and How to Test

A fire in a closed cabin, engine room or lazarette can grow for minutes before anyone notices. Learn where smoke alarms and heat detectors make sense aboard, why boats are hard on household alarms, how to power and test them, how they fit with CO alarms, and how automatic engine-room extinguishers and engine shutdown tie in.

Learn how start isolation and dual-circuit battery switches keep the electronics on their own battery, how to find and test the start-only wire, and what to check after the job.
