Dyson class. This one?:

I see it has a workboat “hidden” in a recess.
Don’t know if it is equipped with Vestdavit for launch / recovery but NOAA has a long term contract for service with NOAA:
Is this definition correct?
It more or less follows function (rescue) and type (light boat).
From the same source, more on the “type” of boat:
The boat may be of either rigid or inflated construction or a combination of both. Usually, it is a semi-rigid structure with the inflated chambers of an upper sponson and an outboard engine.
As someone that has been pleasure boating their whole life, some of the worst designed boats along with the most dangerous systems of launching and retrieving are to be found in shipping, thats for sure.
We called life boats death boats on our rig and low an behold one rig in the fleet killed 2 people with one just to prove it.
A davit-launched, motor-propelled light boat provided to perform man-overboard retrieval and raft marshalling duties. The boat may be of either rigid or inflated construction or a combination of both. Usually, it is a semi-rigid structure with the inflated chambers of an upper sponson and an outboard engine.
This definition seems correct as far as it goes but it’s generic. SOLAS uses the term “Rescue Boat” in a specific, defined way.
Conflating the two definitions just leads to confusion.
I repeat:
Most people are able to handle two terms used for the same thing, especially when both are self-explanatory.
There are many example of this in the maritime vocabulary used around the world. Many have been discussed on this forum before.
I call a complete vessel a Ship, while the “body” of that ship is the Hull.
Some appears to confuse the matter by calling a ship a hull.
(Finance people even call it “an asset”)
Some even use “Left and Right” when they mean “Port a Starboard”. Confusing.
PS> That is why there is such thing as “Standard Maritime English”:
This is taught in Maritime Schools worldwide to avoid confusion when ships of different nationalities meet and seafarers communicate in English.
A weedo boat:
Weedo Boat
For towing around oil spill recovery booms.
Also used as work boat on Seismic vessels.
Based on the boats used on Norwegian Purse Seiners in the 1960s (before they got side thrusters) to keep them from drifting over their own net.
PS> Maritime Partners make several kinds of MOB/FRC/Work boats/Ambulance boats etc.:

They’d also a difference in the gear required onboard between lifeboats and rescue boats.
It’s been a while but I can’t recall any difference in the requirements between the two boats.
Is this MARKUS man overboard recovery net, or a similar product, available to order in the US or Canada?
We call that a “seine skiff”. Typically, fiberglass or aluminum. Some of them have 400hp, nozzles, and flap-rudders.The cost has become outrageous.
Facts remain that fast rescue boats carried by my ships shall according IMO/SOLAS be able to be launched and recovered at sea in severe weather by the ship to pick up people in the water and that regular training/testing of boats, appliances and crews shall be done in severe weather, i.e. >B6 and >3 m waves. As plenty seamen have died during such testing/training it seems such requirements have been abandoned even if the Rules haven’t changed. IMO has proposed that PSC does not demand proof of training and testing of fast rescue boats and crews. I would never suggest such training in severe weather.
17, 23, 26, and 34 are required in rescue boats and not lifeboats (23, 26, and 36 aren’t required on a ridgid rescue boat) and 39 is required if your lifeboat is also the rescue boat.
So a buoyant fixed blade knife and a tow line are required in addition to your normal life boat equipment.
To maximize safety during launching and recovery in heavy weather you really need a high-tech system like seen at the video below. It is well beyond what IMO/SOLAS require. The painter and davit wire have automatic tensioning so automatically adjust the tension appropriately when big waves pass-by.
On a ship with two davit-launched lifeboats there are two boat that are required to meet same exact requirements, each carry the same equipment and one is designated as a rescue boat.
On a ship with a single free-fall lifeboat and a rescue boat the boats are not the same and are required to carry different equipment
The notes 4, 7 and 10 apply. A lifeboat that is designated as a rescue boat is a “rigid rescue boat”
For the fixed blade knife the hatchet counts in a rigid rescue boat. Both the lifeboat and the designated rescue boat are required to have a hatchet. A tow line is required for lifeboats, including those not designated as rescue boats.
EDIT: A tow line is only required for a rescue boat but the lifeboat is required to carry two painters (#21) while the rescue boat is only required to carry one painter.
This is a tow line:
But the towline and the painter have to be the same.
That’s not what the quote you provided says. It says the towline must be no shorter and no thinner than the painter. That’s not “the same” because the tow line has different requirements than the painter.
You’re right, they don’t have to be the same. So it is possible they could in fact be different.
But they do have to meet the same requirements so in practice they also could be the same.
They’re is no requirement I’m aware of for the painter(s) to be buoyant.
