Motivator’s Dinghy Davit
UMT’s facility is
located in the Fort Lauderdale area, so they dispatched a company
representative to meet with me. He
assured me that the crane was rated for 1000 pounds and somewhat over
engineered. The 850 pound dinghy we were
considering would not be a problem. But, if I wanted to upgrade, he was my man!
Emergency Crank
Handle
(Moves the cable ½ inch
for every 20 revolutions)
After examining the crane, the representative proclaimed
it to be in excellent condition, and gave me an emergency crank handle for
free. When I asked about documentation
such as an owner’s manual detailing maintenance he said that all they had was
on their web site. All I needed to do,
according to him, was occasionally lightly oil the cable. Note: their web site is very lacking on
specifics.
Down island we noticed that rotating the dinghy once it was
lifted was problematic. Again I contacted UMT asking for an exploded diagram of
the davit so that I could understand its configuration better. Again I was put off. After fellow cruisers pointed out that our
method dragging the dinghy into position above the cradle with Pollie hanging
off the side of the raised deck was dangerous, we devised a system using a
block and tackle to easily rotate the dinghy into place.

dinghy’s bottom
Like other boaters, we were in the habit of leaving the
dinghy davit in the up position after deploying the dinghy, and only lowering
to the stored position when we were preparing to get underway. A practice we no longer employee due to water
intrusion.
Hand Held Control:
$195 + Shipping from UMT
$86 + Shipping from
Dutton-Lainson
After a particularly rainy period, I retrieved the hand held
control from its storage place in the davit and noticed that it was suffering
from severe water intrusion. Several contacts
had corroded badly. I was able to give
it a temporary MacGyver while a new control was ordered from UMT. At that time, I told the UMT representative
that the winch seemed to be making more noise and that the dinghy seemed to be
descending more rapidly than before. The
UMT representative assured me, “They all do that.”
Blown contacts
We waited in St. Kitts while UMT accessed a hand
held control unit from their supplier (evidently they do not stock the item)
and shipped it to us. The first time we
tried it under load, two of the contacts in one of the new switches in the hand
held unit blew apart (in my hand!).
Again, I contacted UMT and was told that is not supposed to happen, but
they had little more to offer. After doing
yet another MacGyver on the switches, we got the dinghy lowered one more time
before the motor in the winch gave up the ghost completely.
Towing the dinghy, we
headed for Puerto del Rey Marina in Puerto Rico where Martinez Marine Services
is located. Jose Luis Martinez installs
and services a variety of dinghy davits including UMT units. By this time I was somewhat disillusioned by
UMT’s support, so it was time for an end-run around UMT. I started researching the unit further.
Dutton-Lainson tag on
burnt out motor
I was soon able to deduce that UMT builds the metal
structure of the crane and then stuffs in a Dutton-Lainson StrongArm electric
winch sans cover. Added is a stainless
steel cable and weighted carabineer. The
fine people at Dutton-Lainson were very knowledgeable about the winch and were
able to inform me that the winch requires periodic maintenance (more than simply
oiling the cable). They also informed
that the use of the winch with worn braking would burn out the motor. Snap!
New brake springs
A completely new replacement winch was ordered from
Dutton-Lainson (and unfortunately shipped by slow boat to Puerto Rico).
"CAUTION: Continuously
running in excess of 3 minutes will damage winch motor."
(Good to know!)
The cover and cable supplied were removed. Martinez Marine did the reassembly and new
stainless steel cable installation. In
the process they discovered that the reason the arm was so hard to rotate was
that the original installers (presumably UMT International) had managed to get
the supply wire crushed into where the crane arm and post meet.
Martinez Marine
supplied spare brake disk and springs
Once a year or more depending on use, the winch
should be removed from the crane, gears greased, bearings oiled, and brakes
inspected. So, bottom line, with proper aftermarket
support, less than $50 for parts, and a couple of hours labor we would have
saved several months of angsts and over $1000 in expenses.
I now have an owner’s
manual for the winch, but not for the crane.
In my humble opinion, marine suppliers must provide aftermarket
support or they do not belong in the business.
I understand they must markup replacement parts, but over 100% on an
item you are not even stocking - seriously.
Other marine suppliers are not like UMT International. For example Raritan Engineering’s technical
support is stellar and when given the option I replace components with their
products. Teleflex once sent me two new
seals for a steering pump free of charge.
So some companies understand the value of brand loyalty while other do
not.
