The floating LEGO Technic Catamaran 42105 building set allows young builders to pretend they’re world-class speed sailors! They can angle the sails, raise and lower the dagger boards and move the rudder. The fun doesn’t end there. The catamaran cleverly rebuilds into a Power Racing Boat! This feature-packed LEGO action toy will spark imagination for hours of build-and-play fun.
My 7 year old LEGO enthusiast really enjoyed building this model and is displaying it proudly after trying it out in water. He wants to now build a custom stand for it, using parts in is Lego parts bin.
This is a good product, but it really depends what you want it for. It floats good and works good in water, but the building experience isn't very good. Would recommend this for a child's toy, but not for a building experience.
Nice quality as always from Lego. Colors and appearance are impressive. The steering, sail, & keel depth adjustments work really nicely - well thought out. The kit was a bit tricky to build and i think the ages are a bit off - ages 8 and up? More like 12-14 and up, as I think many 8-10 year- olds would struggle with all the tiny pieces and some of the directions. Touch to display with the keels, should have come with a basic stand perhaps. Cool that it floats!
I purchased this set for my son, who is 4 but has a basic idea of Lego’s. Now, that being said I purchased the yellow single hull boat when it was out and thought it was pretty cool. I was even more excited for a boat that would float. I feel it’s a bit misleading. Between the points where the steering fins attach to the boat there is an open hole. So if you were to play with this in a bath tub to any degree the hulls will take on water and sink. That’s my only gripe. Otherwise it was a cool build and can be displayed along with the other sailboat if you can build a cradle for it to sit on with the stabilizers tucked all the way in. Not disappointed, but not impressed. The other green speedboat released in the Lego city line takes on water too. Should’ve been one piece hulls. Oh well, maybe next time.

We're constantly looking to improve our sets and having your feedback is super helpful, thank you for taking the time to write the review. We wish you happy sailing!
As a sailor and a Lego fan, I am super impressed with this model, especially when compared to the previous attempts at sailboats. First, the floating aspect is awesome. Finally it gives us a REAL hulls that floats! The amas are actually very modern, cutting edge even. Reverse plumb bow is amazing. Mast and sails are much more in ratio to real boats. The mechanics are really novel with adjustable centerboard heights and individual sail trim. I suspect the designer is the same as with previous sailboats and finally got to build what s/he wanted. The best part for me, and worst for some, is that it is designed to be FLOATED and not displayed. I can see a ton of new MOCs coming from the new pieces introduced in this set. It is not an advanced set but it is a great representation of what a modern racing catamaran would look like. I plan to try to do some fun rebuilds that were not possible until this set. How about a HARD sail for that boat. Lego lends itself to hard sails very nicely

Exactly, love the positivity! It's the first time we've introduced a Technic™ boat that floats on water. Awesome, right? We can't wait to see our fans get creative and build MOCs with the newly introduced pieces. Thank you for your review and we wish you happy sailing!
