Recommendation: no 3.64 / 5 from 10 reviews

I was totally surprised and excited to finally get a seagoing technic set. Combined with some ingenuity and the proper parts this set x2 yielded a great though somewhat sluggish pond patroller. By itself with the bluetooth batmobile I had a really fun relatively quick differential steering catamaran. Lego dudes, please make me a bigger boat prop!!! Add it to a new series of technic speedboats if you have to. Great summertime fun!! I highly recommend this kit!

The set brings back childhood memories of building a wooden boat with my grandfather, preparing the rigging and the sails and making it cross the nearby pond. 42105 Catamaran essentially embodies the same promise. Fun building and more fun sailing.

Recommendation: meh by VBBN

It's unique, and the functions you build here all serve their purpose very well. The set has a fantastic color scheme, it's got a convincing look, and the final size of the set is pretty large overall; 404 pieces for $50 isn't as good of a deal on paper as the Stunt Truck and Bike which is priced the same, but you get two large floating hulls and those sails to make up for it. With that said, the set feels like it needs to be in water. On land, some of it's functions like the dagger boards, are relatively useless all things considered. It's a fun set, but like many of these, one with a limited audience, I think.

I'm struggling to see the point of this set. It floats, which I guess is cool, but where exactly are you going to float it, given that once it's been 'launched' you have no control of it? The sea? A lake? I suggest that the risk of losing it is too great for anyone to want to do so there. In the bath? Paddling pool? Fun for 3 minutes... A swimming pool is about the only suitable place, where you can keep an eye on it and push it around, but here in northern Europe at least, not many of us have them in our back gardens.
