Dinghy weight for a 44' Sailing Cat

Seeking input from experienced live-aboard cruisers on sailing Cat's in the 42-45' range please.

Our brand new Leopard 44' is arriving next month (so excited) so I am shopping for used dinghy / tender.
I've learned that a quality, comfortable, fast tender is critical to happiness (even had a few salty-dogs say that the tender is second only to anchor choice)...
But I am a bit concerned about weight affecting performance hanging on the back of sailing vessel.
With just two of us and being careful not to overload her, how concerned should I be with an 11' tender with 20HP 4 stroke weighing in around 400lbs?

Nick

Re: Dinghy weight for a 44' Sailing Cat

The lighter weight 11' Caribes weigh in at 154lbs. and the 20hp outboard is about 115lbs for a total of well under 300lbs. With the outboard hoisted to a mount onboard you can keep the weight on the davits down to less than 200lbs. I don't see the 400lbs as the total unless you're talking about buying one of the center consoles. I have difficulty understanding why anyone crusing and interested in using a dinghy to transports crew and provisions would want a center console dinghy. Share your thoughts about the purpose of the dinghy,- crew capacity, provisioning, speed, distance,..... water sports? Maybe you do need a heavy dinghy?

Re: Dinghy weight for a 44' Sailing Cat

Agree - no center consoles.
One is a 11' BRIG w/ 15HP Yamaha 4 stroke, fully outfitted.
The other is a 10'2" WB Genesis with 15HP Honda 4 stroke, also well-apportioned.

I'm guessing either will weigh in around 300lbs.

90% of the time it will be used just by my wife and I for snorkeling, diving and trips to shore.

Are these OK choices for a 44' Leopard cat?

Thanx

Nick

Re: Dinghy weight for a 44' Sailing Cat

This sounds reasonable compared to the 400lbs. I'd still mount the outboard on the Leopard for offshore passages.

Re: Dinghy weight for a 44' Sailing Cat

Leopard should be able to advise you of davit load capacities.

Re: Dinghy weight for a 44' Sailing Cat

Indeed Leopard can advise you on what the safe working load is for your davits. You should also consider acceleration forces (from vessel heave) when calculating your total weight; you should be safe adding 30%. Then the rest is effectively a safety factor margin. If you do any crossings you should consider taking the outboard off and storing it elsewhere on deck. This reduces the load and any effects of possible green water loading. Also make sure your davit rigging is good for the loads; at least that of the davit frames.

The BRIG will probably be pvc, a poor choice. BRIG does make some Hypalon dinks (I have one)so, if you do go BRIG make sure it's a Hypalon one. The knock on the BRIG is that they are very wet with no sheer whatsoever. Also their drain plug is poor, being the type that threads in. The thread is a fine one and the plug is difficult to screw in. May seem like a small issue but it is very irritating.

Genesis has had a lot of problems. Do a search and you'll find them

Re: Dinghy weight for a 44' Sailing Cat

We have a Walker Bay Genesis 340 FTD and a Honda 20hp 4 stroke on the davits on our Catana 48. The outboard lives on the dinghy except for offshore passages when we take it off and put it on a mount on the rail.

The Walker Bay RIBs are lighter than other similar sized ones because of the plastic hull. We are very happy with this combination of Walker Bay and Honda, so much so when our original dinghy got stolen in Italy a couple of months ago we replaced it with exactly the same combination, except in PVC not Hypalon as there were no hypalon ones available for the next couple of months in Italy.

The Walker Bay Genesis 340 FTD weighs 137 lbs, and the Honda 20 hp 4 strokes weighs 104 lbs for a total dry weight of 241 lbs. You need to add a bit for fuel, anchor etc, but you should be a long way under 300lbs for that combo.

Mark.

Re: Dinghy weight for a 44' Sailing Cat

400lbs will be a bear to pull up and off a beach.

Here is a 10 foot 95 lb Cat dinghy.
Fast, Light, stable and turns on a dime at any speed.

Re: Dinghy weight for a 44' Sailing Cat

I forgot to add, you should look at the 20hp Honda in preference to the 15hp. They are the same engine tuned differently so are exactly the same weight and size (but not price). You will not regret the extra HP when trying to plane with guests aboard. This pairing of models is pretty common from most manufacturers so it is always worth checking to see if the next model up is the same size and weight.

Re: Dinghy weight for a 44' Sailing Cat

Doesn't seem to be any of these on the market... only a few built or sold in the last few years.
guess I'll wait to see if they get any meaningful production volume.

Looks perfect though...
thanx

Re: Dinghy weight for a 44' Sailing Cat

Apex a-11 light 116lbs. Not to expensive either. I am now on my second one, the first went with the last boat I sold. Have a 20hp Suzuki on it that will plane 5 people plus gear. All cats will suffer with a heavy dingy hanging on the stern even if the davits can handle it.
