A Boom Brake Suitable For Top Hats.

Some members have inquired about my Boom Brake, so I have put all the info here.

Cost of this Boom Brake which is suitable for yachts up to around 10m is around $100.

[‘ww’ means Whitworths catalogue number]

You will require for a Top Hat:

2 x Twisted Shackles RF 629 [ww76224] $18.50
1 x SS Swivel 6x90 850kg [ww84640] $13.99
1 x block. I used a Riley RM15 and equivalent may be RF51101 [ww6593] $26.95
1 x 25KN Figure 8 Descender Aluminium 5600Lbs Outdoor Climbing Rappelling $13.00

I got my Figure 8 from http://myworld.ebay.com.au/lilylily.123/ but at this time [Oct. 2015] he is out of stock on this item.
DO NOT get the plain figure 8 one as it will jam, it MUST have the horns to work.

6.5 metres of 10mm Double Braid sheet $16.00
1 x suitable cleat to tie off the sheet. I used a 200mm Slimline SS Cleat $18.95
Total $107.39

Using the Boom Brake:

Thread the Figure 8 as shown in the photos.

When in use you have to release it when raising your main sail or when raising the boom to reef.

The tension you apply via the cleat is as follows:
High winds, as hard as you can get it on and in light winds just firm will do.

I had a loop put in one end of the sheet but it needs one at each end so you can end for end it as the Braid cover becomes worn at the Figure 8. That will take some time as I have been using mine for six months continuously now and I think twelve months continuous use would be require before end for ending.

I have NOT had a jib since installing the system.
