The Seabrake is the chief product of Seabrake International and is the origina patented invention of Captain John Abernethy. The drogue comes in a range of sizes and is suitable for both power and sailing boats.
Unique Features
- Twice the drag of conventional sea anchors & drogues
- Up to 11 applications including emergency steering
- Superior durability
- Doesn’t rotate and is tangle free
- Formally tested by credible authorities and institutions
- Original design
Product Range
The Seabrake GP range of collapsible drogues is designed for power and sailing vessels for operational speeds below 12 knots.
Operation and Application
The Rigging Suggestions and Specifications Chart includes suggestions for each model of Seabrake and when used will assist to attain optimum performance.
Assembly
Assembly and Deployment Instructions are the same for all models of Seabrake.
Consult the Rigging Suggestions and Specifications Chart to determine appropriate length and size of chain
, rope and shackle for each Seabrake model.
- Attach appropriate length of chain to the stainless steel thimble of the Seabrake.
- Attach appropriate length of warp of a good quality UV stabilised polypropylene woven rope to the other end of the chain with a lockable shackle.
- Place Seabrake in its bag with thimble at the top for easy access and rigging.
Note: If using a trip line attach 80 metres (263 ft) of good quality polypropylene rope to the straps at the base of the Seabrake.
THE NON-USE OF A TRIP LINE IS RECOMMENDED UNLESS PROFICIENT WITH THIS METHOD
Deployment
Assembly and Deployment Instructions are the same for all models of Seabrake.
Note: Tie off the warp (and trip line if attached) before deploying. Ensure that the trip line is on a separate cleat and is run out ahead of the warp so as not to prematurely trip the Seabrake.
- With chain attached (shackles wired) secure tow line around a strong cleat or bollard and launch off stern to one side at very slow speed.
- Keeping the seabrake close astern check to observe that the chain and unit remain submerged and stable.
High levels of drag exist at very slow speed.
- Ensure that when the Seabrake is deployed the warp will not be obstructed by railing, stanchions, rigging or poop deck structures and keep limbs free of the assembly.
- Using a transom cleat or other suitable tie off point that is strong enough to support the load that the Seabrake will apply, ease the Seabrake out under restraint to approximately 3 boat lengths.
Remember IF IN DOUBT – LET MORE OUT - For rough weather operation tie the Seabrake off the weather quarter (see How to Rig below).
Applications
Seabrake has many applications including:
- DROGUE, anti-surfing/ broaching device
- EMERGENCY or secondary steering
- STABILIZER, underway or at anchor
- SEA ANCHOR and drift anchor
- AID FOR bar crossing, autopilots and vessels under tow
- SPARE or secondary man overboard harness/ bosun’s chair
