A fin keel yacht is usually supported on its keel in a rubber lined trough, and there are four adjustable height side chocks beneath the hull and a bow chock. For boats with sloping keels, the keel support slopes so that the waterline remains level, as is the case with this trailer for a Dragon.
Other boats that require a slightly different concept include the Beneteau 25 " the Squib, depicted below.
The Immersion Kit is useful if you plan to immerse the trailer to launch and recover the boat.
The kit consists of a flushing system which allows all the brake drums to be flushed out from a single ½" hose connection.
To be effective this flushing must be done immediately after immersion before the salt dries on the brake parts.
We recommend that the trailer is rocked back and forth a couple of feet while the flushing is taking place to ensure the fresh water is distributed around the brake mechanism.
Also included is a system of brake transmission cables which eliminate the usual bowden cables which can cause problems if they become sticky or seize up.
