Deflated, the SD518 boat will fold to the size of one large and heavy bag with tubes and another large and heavy flat bag with a floor. Once deflated and folded, the SD518 inflatable boat can be stored in the back of your SUV or minivan, large closet of your apartment or in a garage. Folding hand cart is highly recommended to move deflated boat around. Dinghy wheels are available to move inflated boat on a ramp.

Double layers of fabric at the bottom of the tubes and a rub-strake protector along the keel provide extra protection from sharp rocks and abrasive sand. The safety valve will prevent excessive air pressure in the boat's chambers.

Quick Tip! Worried about the heavy weight of a hard floored boat? Don't break your back! Get a foldable hand cart from any retail store to carry the folded boat around. Even inexpensive dolly movers will work great for transporting a folded or fully inflated boat. Get dinghy dolly wheels to easily move the inflated boat across the shore and into the water.

Note: Specifications and accessories are subject to change without notice. Max O/B Motor means: maximum power of outboard motor that can be safely used to plane the boat loaded to the maximum capacity at normal water surface conditions. Please exercise common sense and caution when using maximum motor capacity. Do not jump from wave to wave as new 4-stroke motors are much heavier then 2-stroke and provide extra strain on the transom. Under normal circumstances, with half the maximum persons/load capacity, 50% of maximum O/B power rating may be necessary to put boat on plane.

Awesome. Configurable fun

The SD518 is the biggest inflatable boat I have ever owned, it's massive. The floor is quite big and heavy as well so we had to put it on a permanent trailer, while we can deflate it and roll it up it's quite a bit of work. Other than that I am massively happy with it, it's spacious and it handles really well. I plan on putting a canopy like I have seen on the pictures. So far with a 25hp it moves really well although I would love to try something even stronger. I can recommend this or any of the other models in boatstogo store.

Love the boat but the manufacturer's statement of origin is not completely filled out by the manufacturer so I don't know what to do

I bought this boat to replace a different 14 foot infatable that had seen it's day. I got his with the center console and it is perfect for use in my boat lift repair and maintenance business. It's rugged, stable and runs great with my 1980 25 hp Evinrude, and all my tools. It is also great to runabout in on the weekends with my girlfriend and her daughter. I highly recommend this boat for anyone who wants a work or play boat, big enough to get people and gear around. Very economical and affordable. I loved it so much, I just bought the 330 as a dinghy for my 50' boat.

Estoy interesado en el ( 18 SD 518 , estoy retirado y me dan muy poco, si lo bajas de precio me avisas. Gracias

HOW MANY KILOGRAMS HAVE THE BOAT ?

I haven't had any issues with mines since I got it about 2 years ago. Its large and strong, I can fit lots of people in it. Wish I would have had more color options.

Bought the 18ft boat 4 years ago. Put a 20hp Honda with hydro foil on it and have been using it in the San Juan’s Islands Washington as the primary boat. Have hauled building supplies, people, garbage, crabbing and fishing in it. It gets used as a pickup. Zero issues and will by another one if I ever wear this one out.

Order extra valves and extra proper valve adapter for your pump. I discovered a cracked valve in my new boat which had to have happened in shipping. If I had ordered extra valves this wouldn't be a problem bc they are quite easy to change with the included valve wrench.

Store covered or indoors especially warm days. The boat will get very taut from air expansion in the sun.

My reason for 4 not 5 stars is:

The boat assembly is a 2 man job. The aluminum decks are very difficult to install alone. Very.

Great customer service from Eliot who responded promptly to emailed questions. Service gets 5 stars.
