Because most boats dont require it... the fire hose spray is a 2001 thing! The longer the boom, the more leverage the skier has on the boat. It can make driving a little more difficult. Adding length requires more material- making it weigh more and cost more. |

I used my straight BI boom on my 88 all last season with nothing other than the clear hard plastic sleeve that came on the boom. No signs of spider cracks even though the boom falls right on a corner of the gunnel when used in any way other than the straight out the boat (kids height).
Of course after reading this thread, now I'm paranoid about looming spider cracks and plan to use a cushion this upcoming season. Regarding the extension, why the hell didn't Siepel just make the boom longer to start with? Make it a 3 piece or something. The BI product seems to be well built but pricey. Plus all the BI "nice to have" accessories (I.e. not 1 but 2 recommended extensions, gunnel saver, height adjuster, kids smaller diameter handle, etc.) is even more costly. I did w/o the extension last year and got blasted with that chine spray all season. My ski partner purchased an extension for us over the winter so I'm really looking forward to checking out the difference. Thoroughly enjoyed the boom last year btw. At $250, you did real good. |

Keith, I know youre probably joking, but Ive run a boom on my Skier- similar size to your Skylark- and it worked just fine. |

We added a step pad that matched the ones on the gunnel in the back to our Malibu. It provided protection against scuffing and spread the load to reduce gel cracking. It also allowed people to enter the boat more forward without stepping where they didn't belong. I think a boom on the Skylark may flip it, so I don't plan on trying that.

I my case i used another board perpendicular to spread the load in the floor...something like an inverted T... I used my rig a couple of times..but its kinda bulky when not in use.... |

Ive climbed onto a boom or 2, so count me as worried if the boom is resting on the corner of the gunnel! I cant recall which boat I saw with the damage, but I know Ive seen it. Brad's '86 has some damaged vinyl in that spot as well. All it takes is a weird fall and that boom can move around a bit, so Ill keep my ugly cushion.

Meh. We don't really put much downward pressure on the boom. I guess if I had guys completely hanging off it, etc. that would be a different story. Typically it's kids learning to ski or a couple quick runs on the short rope. Mark this down as one thing I'm not worried about that Tim is. What boats have you seen spider cracking on? The 90? |

Mike, if your boat is roughly similar to Scott's boat, then you should have the option to mount a universal contour either forwards or backwards and still not interfere with the tower (or windshield).

I dug up this pic. I have a straight boom on my boat, and it is angled back slightly. I did install the tower myself, but the picture should give you an idea for your tower/boom.

So in these pics, they're showing a boom that would go back behind the windshield frame on some boats, and potentially behind our rear tower foot/leg.
Boats in storage, might dissect some pics in a bit. |

No need to wait til spring, Mike- all you need is access to the boat and a tape measure! Heck, you could probably eyeball it.
Those descriptions are good, but the pictures are useless- they used the same pic for both booms (its a universal contour- note the angle of the clamp... a "straight contour" would sit flat on the ground). |

Tim, waiting till spring and seeing if it actually works on our sport would be too easy. I would rather write pages of forum posts than sit here wondering what to chat about on CCFAN
These pictures are the same, descriptions show what Tim is referring to. hmmm, makes me wonder which one we have! I will have to check er out tonight. |

Depending on the boom/windshield/tower configuration on any given boat, mounting a universal contour boom forwards is usually an option. Most (but not all) universal contours have square bosses, allowing it to go forward or rearward for both sides of the boat.
The boom posted above does not appear to be a BI, but clarification on their terms: universal contour = bend down AND forward (or rearward). (This is the most common style and is often referred to as just a "contour") straight contour = bend down only. This style is not very common, as most of the MC's and other tourney boats with the tapered pylons that required the downward bend, also had swept back windshields that required the bend towards the rear. Mike, just because Ryan's 206 does not have problems with the tower interfering with the boom, doesnt mean that you wont encounter an issue on your Sport. 2 different boats with potentially different pylon, tower and windshield geometry. You may actually have to look at your own boat to determine if you'll have an issue! Im not crazy about putting a 2x6 boom support on the floor... with the moment a barefooter could potentially put on the boom, youre talking about a pretty serious amount of downward force, on a pretty small area. I could see damaging the fiberglass floor. Its not pretty, but I think I'll keep my gunnel cushion! |

Steve if you put your boom out the passenger side you will be able to have it angled toward the bow of the boat. This should help get you away from the chine spray. At the moment your boom would be angled to the stern getting you further back and into the chine spray.
The main reason I kept the "step sister" tower on my 98 Sport was that I was able to rig up a nice tower boom mount. Easy to setup with no boom inside the boat restricting access. Copied BoomMate 6000 on my 89 SN2001 but still used a throw cushion underneath for extra insurance. |

Andy has a good idea there. Several people have done just that. I think Kapla rig something up like that on his. |

The booms are all fully adjustable, just shorten or lengthen the cables to get your boom where you want it. By shortening cables you can get your skier forward of the chine blast quicker. There is no rule that a boom must come out of the boat at a 90 degree angle.
The boom extensions work, the gunnel savers work very well. If you are still worried about spider cracks take a piece of 2x6 cut to length with a notch on top, carpet it or not, set the boom on it and the boom will be braced to the floor won't even touch the gunnel. |

I think that is a double contour. |

Does the protector lay flat on the gunnel? Or does it hit the corner? I can see it being sufficient if the former. If the latter... then I would (and do!) use the additional cushion. |

We just use the built-in rubber protector thing on the BI boom FWIW. Gunwale seems very solid on the TSC1.

Does that thing spin around and move up and down to fit accordingly? The boom we used to use on the 90 was from a Malibu Flightcraft and the BI boom protector was no where near the gunnel so we used a roll of ugly carpet. The protector didn't seem to want to budge. |

Never had a problem with the BI boom protector. If people use the boom incorrectly that is more of a problem. |

We had the same style boom on the 90 for 5 years that we borrowed from a family friend. Didn't really have any spray issues there so we'll see how it goes.

I have 1 extension and made a huge change, 2 would be best I guess but probably would make steering the boat a little harder...
donĀ“t know if the cable lenght allows for 2 extension... |

Yes it is a contour boom. One other thought, actually a couple... You won't have any problem working in the boom (on either side of the boat) with the tower. The issue is going to be the chine spray. It really gets you when you are working on starts, once your up it lands just behind you on a 6 foot rope.
For footing with the standard contour boom, I put two fat sac cubes opposite side stern. This helps to reduce the chine spray. I purchased a boom extension at the end of the year but did not get to use it. I expect that is going to make a big difference. Mike (Seipel) will tell you to use two. |

I think this pic I just found shows that it'll be good to go on our boat with the tower. I know this is a Ski vs the Sport but both are pretty similar when it comes to what I'm worried about.

bahaha He had a tower boom there...after doing some research on them I just didn't think it'd be the best fit for us.
Is your boom a contour Steve? |

Thanks Mike, I do too!
This shows the configuration a little better: Maybe you can call Siepel up and trade the contour in for a tower boom, get the electric hoist option too! As long as your buying, have him throw a super fly high in! |
