Walder Boombrake Help

[TerryP]

Wondering if anyone has experience with a Walder Boombrake. I would like to know how they work? My present boat is a 28' Tri and I'm looking at the Walder Boombeake Model 403 which is listed for a larger boat then mine. I'm thinking that I might upgrade to a larger boat someday. Can I get by using the larger unit on a smaller boat? It appears that the boombrake works on friction by wrapping a line around the drum, just like a winch. The model 403 uses 9/16 line and I want to drop down to 3/8 line. Do you think that this is feasible?

TIA

The #403 Walder Boom-brake is recommended for a much larger boat, in the 39 - 52 foot range.
There are a number of smaller units, such as the #203, rated 28 - 38 Ft, and utilizing an 8mm (5/16") diameter line.

They’re “pricy” items, at about $500 USD the #203 is only 75% the cost of the #403 (about $675).

The Walder Boom brake was popularised in the mid-l980s, following the first BOC Challenge. Philippe Jeantot won the race and use the Walder Boom-brake all the way around the world.

Thanks Gord, I've found a used model 403. Thats why I'm hoping I can make it work.

I don't believe you should "significantly" reduce the specified line size.

I have the Dutchman Boom brake. It's pretty much the same but I would not go out with out it now. I just about tore my arm off on an accidental jibe once and that was enough to convince me that the cost was nothing compaired to the pain a boom can conflict on a person.

You won't need to set up a preventer ever again. But you do have to get the attachment points in the precise spots for it to work 100% the way it's suppose to.

And Yes, go with the line size it recommends. Too small will cut into the sheaves!......................._/)
