We'll just 'vote', chirping in our own experience FWIW...
We inherited a 3.4m RIB and a 6hp 4-stroke Yamaha. The RIB was heavy; it had no seats; nor an anchor locker
; and there was a slow leak...and it was filthy...
So the Admiral ordered there should be a new RIB...and, of course, the orders were followed.
The new RIB is 3.1m hypalon, much lighter and with both seats and an anchor locker
There is a cover, but we only put it on -- It is a bit of a production to use, covering the whole RIB & engine
-- when we're not cruising.
The Yamaha only planes with 1pax, but it still moves along reasonably with a full load (4pax + gear) and the lower hp keeps the overall weight down. We're never in that much of a hurry, so the little Yamy's still there.
If you're looking at an overall budget
for the RIB, we'd join the others who confirm that including in your budget
a power winch
for the RIB is a great idea. Both security
and silence suggest lifting the dinghy each night...and a power winch
makes that job simple for anyone.
We would also add that others' nasty experiences with dinghy movements at sea suggest you should plan your dinghy position so that it is well-and-truly secured when you're on 'blue water'. There are multiple strong points around our davits through which we run a separate 'blue water' line that triple-secures (after the dinghy is already fully raised, and bow and stern lines are snugged tight to cleats) the dinghy, eliminating any movement and providing a backstop to the other lines; the 'blue water' line is a bit awkward to put in place, but it is removed when we're on protected waters.
The Admiral would probably still like a big, flash dinghy and a bigger motor
, but she also likes sailing along at a reasonable pace. So ours represents a compromise...less weight & cost, with acceptable dinghy use comforts.
