Hiring a Diver for In-Water Hull Cleaning: How Often, What It Does to Your Paint, and What to Ask

If your boat lives in the water, a hull-cleaning diver keeps growth off the bottom, prop and through-hulls between haul-outs. Learn how often to schedule cleanings, why scrubbing wears away ablative paint, the local rules some harbors (like San Diego and Marina del Rey) put on in-water cleaning, and what a good diver report should tell you about zincs, the prop and the paint.

Hose Clamps on Boats: Choosing, Installing and Inspecting Them

A rusted or wrong hose clamp can sink a boat at the dock, leak fuel or let exhaust into the cabin. Learn which clamps belong on a boat (all-316 stainless, embossed band, T-bolt where needed), when to double them, how tight is tight enough, and how to find the ones that are about to fail.

How Much Is a Used Boat Worth? Pricing Guides, Comps and Condition

Work out a realistic price for a used boat, whether you're buying or selling: check sold and listed comps, read J.D. Power, BUCValu and ABOS values the right way, value the engines separately, adjust for hours, condition, upgrades and location, and know when a valuation survey is worth paying for.

How to Adjust and Replace Trailer Bunks and Rollers So Your Boat Sits Right

How to Build a Damage-Control Kit: Plugs, Patches and a Plan for Leaks

Put together a labeled kit that can slow or stop water coming into your boat - softwood plugs tied at every through-hull, rescue tape, spare clamps, rubber and plywood patches, plastic sheeting, underwater sealant, a manual pump and the tools to reach a hidden leak - and practice with it so your crew knows where everything is.

How to Care for Boat Solar Panels, Connectors and the Charge Controller

How to Check, Mount and Replace Boat Fire Extinguishers

A monthly five-minute check of every fire extinguisher aboard, plus how the 2022 Coast Guard rule changes affect you, where to mount them, and when to recharge or replace.

How to Choose and Fit Life Jackets for Children and Babies

Pick the right Coast Guard-approved life jacket for each child by weight, check the fit so it can't slip off, look for head support and a crotch strap on little ones, and learn the federal and state wear rules. Inflatables are not for kids, and a life jacket never replaces an adult watching.

How to Choose, Install and Adjust Trailer Guide-Ons (Posts or Bunks)

Add or tune the side guides on your boat trailer so the hull lines up in wind and current, the posts stay visible at the ramp and nothing rubs the gelcoat on the road. Covers post vs. bunk guide-ons, lighted posts, mounting height, side clearance and yearly care.

How to Choose, Install and Maintain an Onboard Battery Charger

Pick the right marine charger for your batteries (how many banks, how many amps, flooded, AGM or lithium), mount and fuse it safely, set the charge profile, and use it to keep batteries healthy all season and through the winter. The AC (shore power) side is a job for a marine electrician.

How to Clean, Protect and Inspect Stainless Steel Boat Hardware

Remove tea stains and rust from rails, cleats and fittings without scratching them, passivate stainless so it stays clean longer, understand why 304 and 316 behave differently, and spot the hidden crevice corrosion that weakens fittings from underneath.

How to Clean, Protect and Restore Non-Skid Decks

Get dirt, fish blood, rust and mildew out of textured non-skid without wearing it away, learn why ordinary wax makes it dangerously slick, and decide when worn non-skid needs a deck paint with grip additive or traction pads instead.

How to Clean, Remove Oxidation and Wax Your Boat's Gelcoat (Plus Pontoon Tubes)

Wash your hull the right way, bring back chalky, faded gelcoat with compound, and seal it with wax so it stays glossy and protected from the sun. Includes how to clean and protect the aluminum tubes on a pontoon boat.

How to File a Boat Insurance Claim: Safety, Mitigation, Documentation and Settlement

What to do from the moment something goes wrong until the check arrives: make everyone safe, stop further damage, report right away, document with photos and your maintenance log, handle towing versus salvage, work with the adjuster or surveyor, and understand agreed value, actual cash value and the common exclusions. Policies differ, so your own policy wording always wins.

How to File a Float Plan: What to Include, Who Gets It and What They Do If You're Late

A float plan is a short written trip plan you leave with someone ashore, not with the Coast Guard. Fill in the free USCG Float Plan or the Coast Guard app, agree on a firm 'call for help by' time, check in when plans change, close the plan when you're home, and give your shore contact clear steps for reporting you overdue.
