Kommander Industries BOB Build Thread....

This build thread will go through the whole process from my initial impressions and experiences with my BOB (Bobbie) through the actual build and in to testing and developing the hull to work in the surf.

After riding the hull in Parker, I felt like I would need more forward weight bias to make the hull handle well in the surf. So they moved the mounting points for the fuel tank, water box, and battery as far forward as possible to help with that. And they also gave us the option of mounting the motor a little farther forward also. Jack (at the Ski Clinic) was nice enough to make a box that I could mount in the dash to let me get my front foot a little farther forward as well. These changes should allow me to get a more balanced weight bias in the boat, and help curb the "wheelie" tendency of the hull. That "wheelie" tendency would be great if I was trying to actually flat water Backflip On a Budget...but I'm not. I am trying to build a good handling boat that will also allow me to flip it quickly.

I think it is also very important to keep in mind that the retail price on the boat is $3,500. So my review of build quality etc will be keeping that fact in mind. This is not a $10,000 hull and I don't expect it to be built like one.

OK...here are some pics of the boat as it arrived and some of my initial impressions of the boat. Click on the pics for larger pics.


I'm pretty impressed with the overall quality of the boat. The hull seems quite solid and finish is good. If we wanted to, I'm sure we could buff out the gel coat and not have to paint. Hull seems very solid also. And I like the curved surfaces, flat surfaces break when they hit the water and curved surface will distribute the force better.


Clearly Sidney is super excited about the build.



Pretty innovative ball valve to keep water from coming in the drain. Will be interesting to see how well it works.










Hood looks and feels solid. The air intakes are a little small. But we will be breathing through the hood also. And there is a chance we will be installing some additional air intakes that will be covered by FrogSkins on the top side of the hood.




Multiple mounting locations for the motor.







I opted for the open holds, I tend to put my foot in sideways part of the time. These stick a little too far in to the tray for me to be comfortable with, so we will trim them up a little.





This is the front foothold that I will recess in to the dash. This will allow me a little more tray room and a front hold without using a strap...good to have the room...I'm comfortable in the strap though but I don't think I'll want to run it with the hold.


We are going to replace the fitting on the bow. It is a nice looking piece and would probably be fine to secure to the trailer, but I'm not comfortable with trying to use that to tow with. The good thing is the back side of the mount is easily accessible.

Cool to see some of the changes made to accomodate your needs. The ski clinic does go all out to satisfy. They were awesome about being willing to customize my hull a little and it looks like yours is even more custom. I like the front foot hold, but moving the inserts to move the weight forward is really cool. I can't wait to see what all you do to it.
 
The fun has started...

So last night I stared with the small hull modifications that I felt I needed.


Hole in the dash for the foothold.

Cut the end off the foothold that stuck in to the tray. I will build some of this back with padding when we turf. But by removing that hard piece, I feel like I'm making the tray a little safer for coming back from no-footed variations.
One small issue here is that it looks like some of the glass did not bond very well in the foothold when it was laid up. But I'm sure this is a really hard area to get to when laying the glass in the mold. And there is a bit of a resin ball build up in the corner...no doubt just a little excess. And again please keep in mind the price point on the hull. I'm not at all concerned about either of these two issues. The layup on the section of the dash that I cut out was pretty good, and the rest of the hull feels very solid.


The other side has a bit of a similar situation where the glass in the foot hold was not bonded really well. And it looks like the foam did not quite make it all the way to the back...no biggie.


I pulled a little foam out the the way.

poured a little two part foam in there and taped it up


good to go

Glass work is done on the footholds now. And the front foothold is in, kind of an ugly job, but it is solid.





Overall, at this point I'm super excited. I am very happy at the quality of this boat considering the cost. I think just based on the build quality of this boat it is a great value. I don't want anyone to get hung up on the lamination issues with the footholds. That is an area of the boat that is not structural, and the shape of the footholds along with the fact that they are molded in with the top deck make that a very hard area to lay up I'm sure. The rest of the hull seems super solid and well built. I don't think I have seen an aftermarket fiberglass hull that is as solid feeling as this one to date. But soon enough we will be able to test just how solid it is...

I'm stoked...hope you guys are too.

The next steps will be getting all of our parts together and making a final decision as to what power plant we will be using.

Just a disclaimer....the Kommander is not stoked on my instillation on the front hold last night. And I admit it is pretty ugly but it is solid, and it will be cleaned up before it is turfed.

You are in the right track with the Front Foothold IMO.
When I rode BOB I thought there was a lot of unused space inside the Hull, and the tray area being small, kept your body pushed back. I did not think much of it until I saw Jetmaniac's Daytona Build:

I thought to myself that's what BOB's needs, but again you build your boats to your preferences and riding style. Some people won't justify the need for it. I am digging it though !

ok, that made me giggle...

hull looks sick buddy... do work!
 
RE: Frog Skinz (sp?) This is a company that a buddy of mine Chad Cole (aka The Vanilla Gorilla) is reping product for. It is similar in concept to a pre-filter on a flame arrestor in that it allows air to pass through it and keeps water out, but should be a more effective than the pre-filters and is a different material all together. I've played with some samples and it seems to work pretty well, but we have not tested it on a ski yet.

RE: Weight. I asked them to build it far thicker than they thought it needed to be, and asked specifically for more glass in a few key areas. I've broken a lot of hulls in lots of different places for various reasons. And I don't want to worry about having to hold back because I'm worried about breaking the hull. Besides, weight does not really hurt performance of the boat most of the time in the surf and in my experience a heavier boat handles a little better.
 
We've been running Frogz Skin vents in the snowmobile industry for a couple years. They are even used by Arctic Cat on their race sled air box. It is very similar to Outerwears pre-filter material but with an adhesive backing. They work very well at repelling snow and water. But they will let water threw. I thought about using them when we first saw them and I'm guessing they would work if the area you are using them just gets splashed by water. But if they get submerged if your ski flips or you have a wave come over the ski, I think they would let way to much water in so I decided against it.

Yep that is the stuff... there are some kits ready for OEM SJ and SXR hulls and some other runabouts.

I'm not really sure how exactly we are going to us it, but it is pretty cool.
