  • Sit in boats....

    Since I have decided to put my racing dreams on hold, I still have an interest in the technical side of these boats. Building a hydro still intrigues me even if just for playing around as a lake boat. I am wondering if anyone has tried to build a sit in version of a kneeler.....? I'm not talking about 500-1100cc, I am talking about the smaller classes. I am also not talking about enclosed cockpit but a sit in with an open cockpit.......

    Interesting concept, however in the smaller classes being able to move and keep the boat flying at the proper attitude is very critical, sitting would almost certainly eliminate that, in my opinion. I'll like others to weigh in on this also.

      Drivers don't move much in laydown hydros and they turn just fine. Hoe does that work ?

      The majority of laydown hydros are PRO boats and are running what is refereed to as the "euro" style boat, nothing really new Ron Jones and Ed Carlson did this design 40 + years ago. Design utilizes air pressure differential to make boat work, lower center of gravity, much more power also. Faster you go into corner, better it turns.

    I tend to agree with Baries, especially in the smaller displacement classes. In addition, you would have to sit cross legged because you would NOT want your legs in front of you crossing under steering cable, as most boats are designed. Cross legged sitting would not allow you to move much, would likely be very uncomfortable and might require the cockpit to be even wider, depending upon your size. Some of this has resulted in the "lay down" format we see these days in the MOD and PRO categories.

      If your looking to sit down, take a look at one of these. http://www.dillon-racing.com/index-m.htm You could build it yourself as I believe he sells plans and you have either a tunnel design or a deep V design to choose from. Would be fun on a lake or river and would handle those water conditions.

        Re: Sit in boats....

        I too wonder how the laydown boats and the cockpit boats seem to run well with little to no driver movement. If it is just a matter of boat size than maybe you build a bigger boat. However my personal idea is to install a sliding seat rig exactly like rowers use in their racing shells only slightly modified for outboard racing. Since to be able to use a sliding seat the rower has to both slide backwards and forwards. To slide back forward their feet are tied into a set of shoes that are bolted to the foot plate. Obviously you can't tie yourself into a hydro in case you flip or roll you will need to exit the boat. So what I would do is arrange bungee cords to the seat to basically hold it in the forward position. After coming out of a turn you push against the foot plate to move your body towards the rear of the boat. When heading into a turn you allow the seat to slide forward and you can adjust anywhere in between simply by pushing against the foot plate. Everything on the boat stays the same.

          This is what a sliding seat looks like. This was a boat that broke in half at the cockpit. My brother and I straightened it, re-aligned the boat then tore out all the carbon and re-skinned the honeycomb core with new carbon fiber and other then stiffened the bottom. This is the finished repair.

            There used to be a set of rules that covered the sit down cockpit style Stock Outboards. Tilt was allowed as i recall. At max up tilt the height restriction of the class would be enforced. There was an ASH built in the 90's if memory serves..I've tried to lookup details on it, but haven't found anything...I'm sure there are people on the site that remember it adn could probably give more details as good and bads of the hull...

              Dad built the boat and sent it out to Rusty and Joey Ray in Washington.

                  its my understanding there was a class of Fiberglass sitdown tunnel hull boats in Texas and they may have run Y102's some time ago.

                  anyone know anything about this?

                    There is a gentlemen named Charles Large that lives down in MX that owns a set of molds for a boat just like shown above. I have talked to him a time or two on FB and I believe he got the molds from somewhere down here in TX. I believe he has the molds in MX with him now.

                    This is a picture of a boat pulled from those molds.

                      PERFECT, thanks
                      I have been told for a couple years by many people (in the know) that this wont work, no way it can get on plane with a small prop race motor, Ive kept digging for info as I didnt believe it. now that I have both the hull and motor and see for a fact its already been done I will go ahead with setup and see if it will make me happy

                      thanks again, cheers

                        Leigh Furnal built a sit down ASH for Rusty Raeís son Joe to run. That is the boat Iím sure you are thinking about.

                              Dale Ropp built a D runabout that ran very well in the Marathon Nationals for a couple of years, don't know what happened to it.
