Two weeks ago we had 35mph winds. We wanted to get out one last time. We packed up and hit the road to the lake. As we started driving and the wind got up to 45mph, over my boat went on to its side! I was driving 50mph. I had to stop on the freeway and flip my boat from its side. The cross arms on my trailer kept it from going over. All that broke was a turn light. We turned around and put the boat away for the year. ![]() Life sucks! We have snow and ice on our lake!!!! |

Hey Burley how about, it maybe we should build a couple of ice sailors!! I have never seen any ice sailors in Saskatchewan. Do you have any windsurfer sails? I have about 3 old windsurfer sails that would make nice ice sailors and we could download plans off the internet. ![]() |

Roy, I heard you can get those ice boats going 30 to 40 knots! wow. And no life jackets needed........ but wear you helmet! ![]() G. |

Hello Roy, We woke up to 4" of snow. I hate snow!! I wanted to build a ice boat last winter but never got it done. We leave on Wed. for six months in Mexico. You will have the ice all to your self. ![]() |

We've had that same problem here in Division 5 on several different occasions. Keep in mind that the trampoline is often shielded from the wind by the towing vehicle. If it is not too much hassle, it helps to lower the point where the mast is supported by the front support to lower the leverage the crosswind has on the mast itself. Also, if you don't want to go thru the brain damage of removing the trampoline, or making any other changes to the way you set anything on your trailer, you can consider doing what we do. If there is enough of a crosswind that we are worried about the boat blowing over while going down the hi way, we put 5 gallons of water in each hull. If we are really worried, we put 10 gallons in the hull that would most likely lift based on the direction of the wind relative to the direction of travel. Gotta be careful not to over do the water in the hulls thing tho. Ten gallons of water is about 75 pounds. That's a lot of extra weight sitting on the point where the bottom of the boat sits on the roller. Also, be aware that the water is going to be sloshing around on acceleration and deceleration because the hulls are not baffled. One last thing, be sure and drain them once you get to where you are going ! Stephen |

Um.. why wasn't your boat strapped down? I trailer mine with the tramp on.. but put two straps across it. |

Thanks for the info. I am trying to think of ways to add some lbs. How do you put the water in your hulls? I would think that a garden hose would work but, how would you know how much water your putting in? What do the rest of you guys think about the idea of water in your hulls? I love sailing on days with big wind but, you have to be able to get your boat to the lake first! |

Personally, I wouldn't purposely add water to the hulls. My tow vehicle is only a 4-cyl, so it's bad enough towing a dry boat. Adding another 100 to 200lb would kill my car's performance that much more. Also, if I were going to add weight to the hulls, I'd want it to be solidly held in one spot. A couple hundred pounds of water sloshing around in the hulls could cause handling problems too during braking and accelerating and could throw the trailer's balance out of whack. Simplest solution is to just slow down. If you know there's high wind gusts and you can feel the trailer getting squirrely don't drive so fast. sm |

If you know there's high wind gusts and you can feel the trailer getting squirrely don't drive so fast. sm I understand your reluctance, and I did not mean to imply that it is something we do on a regular basis. However, having seen boats/trailer combinations blow over while traveling thru Wyoming, and along the front range of Colorado where we get some wicked down slope crosswinds, it IS something I have done on a couple of occasions. I don't KNOW that it averted disaster, but it did give me a good deal more peace of mind as we continued our trip home. Water weighs about 8# per gallon, so 10 gallons in the windward hull approximately doubles the weight of the hull. If your car won't handle an additional 75# you may have an inadequate tow vehicle. I mean really, 75# is the equivalent of a 12 year old kid. The windage of the boat itself is much more of a drag on the towing vehicle than the weight. I totally agree that the idea that the water is sloshing around as you accelerate and decelerate is a bit of a concern, but as I said, this is not something I do on a regular basis, and when I have had to do it, I have already reduced speed, so being a little more gentle with the gas pedal and the brake pedal is no big thing. For your consideration, one other thing I did this February on the way from Havasu back to Denver was to tie 40# of sandbags to the tramp where the front crossbar joins the hull. I didn't want to use the water because of the possibility of it freezing inside the hull and creating a problem. There was a wicked front ( 50mph gusts, travel advisories and all that) blowing west to east as we were traveling north on I-25, After seeing the windward hull lift about 2 feet, and knowing that the wind was blowing in a snow/ice storm rather quickly, I didn't want to just pull over and wait it out, or slow down to the point that it would catch up with us. There are always options and no perfect solutions, just throwing out ideas for people to consider so that if someone finds themselves in an uncomfortable situation, they will have thought about ways to deal with the problem, and decide on the solution that best fits their particular situation and preference.

I towed my car through some canyon on the way home from Lake Mojave, NV. I thought something was wrong with the trailer cuz it kept swerving into the other lane. A flat tire maybe? I get out and its blowing so hard i can barely walk back to the trailer... probably 50+mph. No flat tire just crazy wind. But i never had the problem you did. Maybe you just got a big gust under the tramp and the tramp acted like a sail |

I would take the tramp off when traveling. It's not that time consuming to put it back on so why not take it off. Or you could get a mesh tramp, I just bought one and have had no problems with wind at all. |
