What you need to know about Boat Insurance in South Dakota
South Dakota doesn't require boat insurance or boater education, but it titles and taxes boats, made leaving the scene of a boating accident that causes injury or death a felony in 2025, and requires drain plugs out whenever you trailer a boat. Here's what actually shapes your policy.
South Dakota's Boat Insurance Rules
No South Dakota law requires insurance on a private recreational boat or personal watercraft. You can still be held responsible for damage or injuries you cause on the water, and marinas and lenders set their own coverage rules. We'll help you figure out what makes sense for how you boat.
Agreed Value for Your Boat
Your deep-V walleye boat with a bigger outboard, a kicker motor, and a full canvas enclosure isn't a stock boat. Roamly works with carriers who may value the work you've put in, not some database guess.
Electronics and Gear Coverage
Fish finders, trolling motors, rods, tackle, and wakeboards add up fast. Roamly works with carriers who may offer coverage options for marine electronics and the personal gear you bring aboard.
Coverage Lenders and Marinas Ask For
If you finance your boat, your lender will likely require coverage for the boat itself, and many marinas ask for proof of liability coverage before you can rent a slip or store your boat for the winter. Roamly works with carriers who may help you meet those requirements, and we'll help you get the paperwork in order.
Protection Beyond Basics
Type | Details |
|---|---|
Mechanical Breakdown Coverage | Engines fail at the worst times — like far out on Lake Oahe, miles from the nearest ramp. Through Roamly's carrier partners, coverage may be available to help with sudden mechanical breakdowns beyond warranty. |
Guest Medical Coverage | Summer weekends on Lewis and Clark Lake mean friends and family aboard and plenty of time in and out of the water. Roamly works with carriers who may offer medical payments options for guests hurt on your boat. |
Docking Mishaps | Prairie winds and busy holiday weekend ramps lead to bumps and scrapes. Through Roamly's carrier partners, coverage may be available for damage from docking mishaps. |
Protect the Gear You Bring Aboard
A day chasing walleye on Lake Oahe or a weekend on Lewis and Clark Lake means a lot of gear on board — rods and reels, tackle, tubes, coolers, and electronics at the helm. Many basic policies limit coverage for personal property, so check yours before your next trip. Roamly works with carriers who may offer coverage options for marine electronics and personal effects like fishing and water sports equipment, which may help you replace what's lost or damaged.
What South Dakota Actually Requires
South Dakota doesn't require insurance on a private recreational boat. What the state does require: someone 18 or older aboard when anyone under 12 runs a motorboat over 6 hp or anyone under 14 runs a PWC; a title within 45 days of purchase and annual registration through your county treasurer; a life jacket on every child under 7 when the boat is going faster than no-wake speed, and on everyone aboard a PWC; a stop at any aquatic invasive species inspection station; and drain plugs out whenever you trailer your boat, except at the ramp. Accidents involving a death, an injury, $1,000 or more in damage to one person's property, or $2,000 or more in total damage must be reported immediately to the nearest conservation officer or other law enforcement officer, and since 2025, leaving the scene of a boating accident that causes injury or death is a felony. Going without coverage may be legal, but one collision can mean damage to another boat, a dock, or someone you hurt — and liability alone doesn't pay to fix or replace your own boat. We'll help you figure out what makes sense for your situation.
Real Value for Upgraded Boats
You set up your boat the way you wanted it: a bigger outboard, a kicker motor, a full canvas enclosure, and a better trailer. Book value doesn't account for the upgrades you've added. Roamly works with carriers who offer Agreed Value coverage options — we'll help document your boat so it may be insured for an agreed amount that reflects your upgrades, which may help if you ever need to file a claim.

No. South Dakota law doesn't require insurance on a private recreational boat or personal watercraft. If you finance your boat or keep it at a marina, your lender or marina will likely require coverage. Even without a mandate, you can be held responsible for damage or injuries you cause on the water. Requirements may change — verify with the South Dakota Division of Insurance.
No. South Dakota doesn't require a boater education course at any age. Operators under 12 can run a motorboat over 6 horsepower only with someone 18 or older aboard, and anyone under 14 can run a PWC only with someone 18 or older aboard. The South Dakota Department of Game, Fish and Parks recommends a NASBLA-approved course, and finishing one can help if you boat in a state that requires a card.
It depends on your boat's type, size, value, and horsepower, where you keep and use it, your boating experience, and the coverage you pick. Whether you keep it at a lake marina or on a trailer, how you store it over the winter, and adding physical damage coverage or coverage for electronics and gear will change the price.

Roamly is a brokerage — we work with carriers who may offer coverage options for marine electronics like fish finders and trolling motors, plus personal effects like fishing gear and water sports equipment. Limits and eligibility depend on the carrier, so it's worth asking before you buy. Coverage terms, conditions, and availability vary by state and policy.
Roamly works with carriers who offer Agreed Value coverage options. We may help document your boat and its upgrades up front so it can be insured for an agreed amount, not a depreciated book value. If it's totaled, the agreed value — less any deductible — is what the policy is built around. Coverage terms, conditions, and availability vary by state and policy.
South Dakota doesn't require either one. Liability pays for damage you cause to other people and their property — another boat, a dock, or someone hurt in a collision. "Full coverage" usually means adding physical damage coverage, which helps pay to repair or replace your own boat after a collision, theft, vandalism, or storm damage. If you're financing, your lender will likely require it.
Operating a boat at 0.08 BAC or higher, or while under the influence of alcohol, marijuana, or other drugs, is a Class 1 misdemeanor, punishable by up to one year in county jail, a $2,000 fine, or both. By operating a boat on South Dakota's public waters, you're considered to have consented to testing, and an operator involved in an accident or stopped for a violation must take a breath test on request. If a violation is on your record, Roamly works with carriers that may still be able to help you find coverage. Coverage terms, conditions, and availability vary by state and policy.
It can. South Dakota has no credit-scoring statute, and the Division of Insurance's guidance on credit applies only to private passenger auto and homeowners insurance, not boat policies, so it's worth asking each carrier how it rates. Your boating experience, your boat, and where you keep it are also major rating factors, and how much each one counts varies by carrier.
Yes. Instead of sales tax, South Dakota charges a 3% excise tax on the purchase price of a titled boat, paid to your county treasurer when you title it. Motorboats and boats over 12 feet need a title within 45 days of purchase, and you register in your county of residence, not the county where you keep the boat.
