    Recommendations for a recovery boat

    Would prefer the bottom self righting. What are you all using?

    Refurbished old Tamiya Tug. Good servo and low kv brushless motor.

      ProBoat ShockWave, with (MUCH lower) 1250kV motor, Seaking 120A ESC, and a modified dual-rudder system (so that it turns both directions requalify well, even when pushing the rescue platform & another boat). Also, as I'm running dial rudders, I also added a second water line - first rudder (starboard side) cools the ESC, and exits via a new hole on the port side; second rudder (port side) cools the motor, and exits the original starboard-side hole.

        Very cool I searched around for a tug boat haven't seen much without pulling out the big wallet. Thank it's harder trying to find a recovery boat than it is some thing you're trying to buy as a primary hobby..

          As a thought, we use pool floats, some 3/4 pvc, using the same batteries as our boats.

            Considering buying the harbor freight boat today, to use as a platform.

              Was just able to view those pics, I have seen some similar builds... pretty cool.
              You are using a servo to turn the PVC with the rudder?

                If you run monos, cats, or scale hydros get yourself a springer tug, there are several plans, kits, and hulls out there depending on how much building you want to do, and they are so popular they are easy to come by used if you want something nicer than an RTR and don't want to build at all.

                If you run riggers, knock yourself up something out of PVC pipe and a tupperware pot, a quick search here will bring up several extremely effective designs to take inspiration from, and most are ugly enough that they will make you feel better about the aesthetics of your choice of FE boat.

                  Yes. The rudder and motor both turn. Works great for recovery of both cats and monos. As long as they are not taking on water. Also there is one special fitting. It's a 3/4" pvc furniture tee. Below the 90 that the motor attaches to.

                    Ended up buying a React 17, has the self righting which doesn't matter much for this use but figured my boy could run the battery down playing with it .....after we run our cats.
                    Just have to throw some PVC pipe together with some pool noodles. Shouldn't be too hard of scouted around at a couple ideas others have made..

                      Almsot ordered that Vacu tug...and still may in the future. Looks like a fun build

                        I just tested this out today. Cold here so had to wait till a warmer day but this didn't work so well.
                        It pushed it along slowly but it didn't turn very well. there was a breeze and it didn't have enough turning thrust to turn into the wind but I could get it to slowly turn the other direction to come back.
                        I didn't even have a boat I was trying to push so this is not going to work at all. Planning on getting a different boat and would like to use this PVC set up. I used schedule 40 PVC and probably shouldn't have considering the added weight.

                        It seem to create a lot of white wash rather than thrust from the prop, thinking The prop is too shallow even though the angle of it in this PVC put the prop a little lower in the water, it still didn't have enough thrust. I may look into the vacu tug...any suggestions?A0D854D3-477B-4341-8051-0B0440792AE8.jpg

                          Your captured nose design is likely holding the hull at a bad angle causing the prop to cavitate. The stock prop on that boat is probably too small and the thrust isn't enough to push anything of significance. Less rpm, more prop the the direction to go, but I wouldn't bother trying to make that React into a viable recovery boat.

                            The React 17 is to small, and has way too little power, to be used as a rescue boat. On top of that, you're going to fry the motor, and probably take the ESC with it. The thing is, using that small of, and such an underpowered, motor, you're already overworking it just pushing the rescue platform.

                            I might still be someone new to FR, but even I know not to use that small, and underpowered, of a boat as a "rescue boat". Add in the weight & resistance of a larger boat, and even a snail could outpace it...that if, if it doesn't blow first. As others have said, think 'bigger'.

                              Thanks for your advice, yes I?ve given up on the little boat and will seek out some thing else. Do you recommend the vacu tug kit?
                              Ive got several other projects going at the moment I don?t really need to take on another one but if I have to I?ll add it to the list.
                              I actually bought a brushless Hobby king motor, program card/ESC for this react I can't seem to leave anything alone. I watched a guy that put a brushless set up in one of those and it moved on out handled it pretty well.
