    I bought this at the store, came home and built it in 4 hours. There were a few extra parts and lost one (but found it later!). The build was challenging and the effort was rewarding for this old salt. I was pleasantly surprised with all the move surfaces. I did disassemble it and bagged the parts, and reboxed the kit. :( But I am looking into doing a modification on it so it can be sailed on a pool or small pond.

    Floated the first time but sank second
    Purchased for: Self
    The build was challenging. It’s not really made for 8 and up. The finishing model was nice. The first time I put it in the water the boat floated, but the second time it floated for 30 seconds than sank. When I took it out of the water. It was dripping water but then the bottom of the green boat pieces fell off. I was surprised! Now that is dumb that the bottom of the boat does that. Think of a better design lego!!

    Marine, Customer Service
    Hello, Oh no! I'm sorry you’re having some difficulty keeping the set together to float. We always test and retest our toys to make sure that they’ll hold up to play when they’re built exactly as shown in the instructions. If your set ever seems like it's not very sturdy, the best thing to do is double-check your build. Sometimes there may be a piece just a little off from where it should be. You’ll also want to make sure that all the pieces are pressed tightly together. If you'd like a hand troubleshooting the build, or if you find that any pieces aren't holding together as they should, feel free to give us a shout at LEGO.build/Service-BV.

    Ridiculously Fun!
    I would recommend this to a friend!
    Purchased for: Self
    I bought this on a whim. Not really a fan of boats or sailing, but I wanted a new technic set so I took the plunge. This set was way more fun to build than I expected, and way larger than I expected! It stands about 12” tall, and it can go taller with the adjustable fins that go through the bottom of each hull. My LEGO collection is mostly cars and Star Wars, so this will definitely stand out, but it’s really cool to look at. You should definitely buy this set!
