T&T: Diesel tender

[bob Austin]

Of course it depends on the boat's configuration.  But we used a system to
pull our RIB aboard the Cal 46 which is similar to a Seiner's net boat.
Basically we hoisted the bow up with a block and tackle until it was at the
same level as a large trailer roller (on a SS solid 1" bar which fit between
the stern sections of an aft radar arch).  The boat was pulled aboard with an
electric winch and sat on a teak cradle.  The transom was just on the roller
when fully aboard.  An inboard or jet drive could  easily be adapted to this
type of boarding arrangement--and it avoids a  hoist--plus a tender can be
brought aboard when under way and this adapts very well to the "pushboat" of a
"Yawl boat" used by some fishing and charter sail boats.

An aft cabin type of trawler could have a bracket made over the stern or an A
frame could take the load, brining the boat aboard over the aft cabin.

The major disadvantage of the diesel inboard is taking the boat on the
beach--This can be done with a protected keel, bilge keels or a tunnel drive.
There are lots of ways of achieving this--but it will be rare that you will be
able to have a small diesel tender which will be as fast as an RIB.  In many
areas, fast allows exploration and getting supplies etc much easier.
