A dinghy is a small, open boat between 6 and 20 feet long, used as a tender to transfer people and gear between a larger vessel and shore, or as a lifeboat in an emergency.
It rows, sails, or runs on a small outboard motor. Most recreational boaters own one because their main vessel can’t park at the dock. Whether you call it a tender, a skiff, or a dink, the job is the same: getting you and your stuff from the big boat to dry land when no dock exists.
Types of Dinghies and What Sets Them Apart
The material and hull design decide what a dinghy can handle. Three main categories cover nearly everything on the water.
Inflatable dinghies use PVC or Hypalon tubes that deflate for storage. The trade-off: they puncture, they wander in a crosswind, and rowing one feels like pushing a mattress through water.
For most sailors and powerboaters, a 7-to-12-foot utility dinghy with an outboard motor hits the sweet spot. If you’re comparing models for your setup, our roundup of the best dinghy boats breaks down the top options by size, material, and price.
How Big a Dinghy Do You Actually Need?
Size starts with the mother ship.
- 30-foot yacht → 8 to 10-foot dinghy
- 50-foot yacht → 12 to 14-foot dinghy
- 80-foot yacht → 16 to 18-foot dinghy
But capacity isn’t just bodies — you need room for fuel (roughly seven pounds per gallon), a safety kit (fifteen to twenty pounds), and gear (another ten to thirty pounds). Add it all up and check the capacity plaque on the transom before you load. Overloading is the most common mistake new owners make.
Powering a Dinghy: Motor Size and Costs
Small outboards are the standard choice. Stick to the manufacturer’s maximum horsepower rating — exceeding it can crack the transom or make the boat unstable at speed.
Motor size guidelines by dinghy length:
- 8 feet — 2 to 5 HP
- 10 feet — 5 to 10 HP
- 12 feet — 10 to 15 HP
| Dinghy Length | Passenger Capacity | Recommended Motor HP |
|---|---|---|
| 8 ft | 2–3 | 2–5 HP |
| 10 ft | 4–5 | 5–10 HP |
| 12 ft | 6–7 | 10–15 HP |
What Dinghies Are Used For (Besides Going to Shore)
A dinghy’s primary job is as a tender — moving people, groceries, and equipment between the anchored boat and the dock or beach. Sailors and superyacht crews also use them for snorkeling trips, diving, and running supplies in shallow water that the mother ship can’t enter. Naval vessels carry larger dinghies (typically 12 to 16 feet) for personnel transfer and emergency propulsion.
The term itself goes back to colonial India, where it described small passenger and freight boats working sheltered coastal waters. Today, every cruising sailboat and most power yachts over 30 feet carry one. If you spend time on the water and your boat doesn’t fit every slip, a dinghy isn’t optional — it’s the vehicle that makes the rest of the trip possible.
FAQs
Can a dinghy be used as a lifeboat?
Yes, many dinghies double as lifeboats in an emergency, especially on smaller recreational vessels. But a purpose-built life raft with auto-inflation, a canopy, and a survival kit is safer offshore. The dinghy works best for coastal trips where shore is close.
What’s the difference between a dinghy and a tender?
“Tender” is the job description; “dinghy” is the boat type. A tender is any small boat used to service a larger vessel, and most tenders are dinghies. The word “tender” sometimes implies a larger, more luxurious craft built for longer distances, but both terms overlap heavily in everyday use.
Do I need a license to operate a dinghy?
Requirements vary by state. Most states don’t require a license for a small outboard dinghy, but many require a boater safety education card for operators over a certain age or horsepower. Check your state’s marine law — the rules change at the state line and again between fresh and salt water.
