The single, most important factor is the load carrying capability! This affects everything else. Find out more below�. What makes a boat suitable for extended stays aboard. This page was put together from interviews with builders, designers, delivery captains, owners, charterers and from our own personal experiences delivering boats up and down the East Coast, offshore and vacations aboard with both experienced and inexperienced catamaran sailors.
The information is not intended to support any particular product, though we obviously have chosen Fountaine Pajot because we believe it is a good example of our discoveries. Many people get referred to this page by other dealers and owners. Those are lighter and reduce pitching. Why load carrying is so important for safety, comfort and for you to accomplish your goals. And much more�. The information provided here shows the difference between a comfortable boat and a disappointing vacation.
Sure, in protected waters most anything will do. Many of the older boats literally got away with murder! There was no competition. Much has been learned. New technology has perfectly matched the needs of catamarans to be light, but strong.
Surprise, Surprise. This is the age of spin doctors and marketers. Often with a couple of feet slapped on to the transom! Buyer beware! You will find information here that will narrow the search. Staying at the dock, venturing out for weekends in protected waters?
More ambitious? Coastal cruising? Or are you combining coastal cruising and watching the weather, with serious offshore cruising?
Your plans affect what you need and you need to plan for the most adventurous cruise you plan. We talk to the captains who have sailed all kinds of boats. Visited the plants. This discussion is directed towards offshore sailing.
Why cut off any market potential? Is it built for inshore or offshore sailing? With the advent of new technology the high tech necessary for ocean cruising catamarans is now affordable.
Is he offering an inshore or offshore Cat? The 4 important criteria to consider aside from overall quality and integrity are:. A catamaran generally has no ballast. It primarily depends on beam and individual hull buoyancy for stability. In addition a narrower hull is more easily depressed and prone to tripping in heavy seas.
The same wider body hull that gives you better load carrying ability, also gives you more total stability. Of course at some point, you lose performance� Finding the balance is the key. These same experienced builders put enough beam into the individual hulls to give more than adequate load carrying ability. One sign of an older design often resurrected these days and promoted as new is narrow individual hulls, sometimes supplanted by needed extra beam because the hulls no longer have the required buoyancy.
Watch out! Static stability is a measure of a boats stability. The factor was developed by sign builders what strength wind will blow our sign over?! A bad cat for offshore might have a static stability in the 25 knot range. This is a static measure. In reality, the boat would slide sideways and round up if you were foolish enough to leave all sail up and this would approximately double the figure.
Pitching is caused by Catamaran Cruiser Lil Hobo For Sale too much weight in the ends of the boat. Accommodations and storage areas that extend much forward of the mast. Engines and storage too far aft. Not enough stern or bow hull area extending aft and forward of the nacelle. See the drawings below. Pitching can make your life miserable. Tire you out so you take unnecessary chances. Dampen your appetite. However, solid decking forward does more than just contribute to pitching. Nets simply let the water through and allow the bows to recover.
Long overhangs fore and aft. Accommodations concentrated in center of boat weight kept out of the ends. Short overhangs. Solid decking forward. Accommodations spread into the ends. The extra weight forward is bad enough, but if the foot wells and lounges fill up with water when you surf down a wave at sea, for instance, you can have real problems. Did you know that if you measure these forward wells there can be up to cu.
Ft of water is 7. A gallon weighs 8. So cu. Think about it this way. This is generally referred to as the height from the water to the underside of the nacelle. If it is too low, waves will slap and bang under the living accommodations. Sometimes literally knocking the plates off the table in a poor design.
The noise prevents sleeping. But I amplify this view. Imagine pushing two pipes through the water as in example Cross sect. The pipe with the small hole must create much more resistance; literally forcing a wall of water before it. Pipe A easily allows the water through. A good cat, left, has a higher bridge deck clearance, with no protuberances interrupting the water flow.
The wider beam between the hulls also contributes to uninhibited water flow between the hulls. Note the difference for the bad cat on the right. This is also one of the biggest reasons for them selling. This style is typical of many of the older generation of boats, and also some new ones where marketing types take over from the designers. Why not too much beam? Have you ever observed the wake coming off the bows of a boat? The wave curves up and away at an angle about degrees back from the bow.
If you measured diagonally outwards from the bow, you would see that the wave increases in height as it curves away from the bow. Keep this in mind. Now, imagine an older design catamaran with narrower hulls The waterline beam of each hull being narrow. The trade off? Several and all bad:. Why would anyone design a boat this way? The problem is that a bad design will always be a bad design and the cost will long be forgotten while the discomfort will linger�.
These boats, typically only need to sail in a 50 mile circle. This may be the most important point of all. It is difficult to maneuver in tight situations or when docking. This hull submersion also decreases the bridge deck clearance, which promotes hull slamming as well! Some dead giveaways. Not enough load carrying. Is the waterline at the water or below it at either end or entirely?
Note, the waterlines on both sides are still well above water!
A vessel was junk though I was able of deliver a steering ocean cruising catamaran off of it as well as I will operate a trailer.
I began with a first TOH as well as have one after another to this indicate. Once they have been stitched up, however as most as anything I simply good from a assent as well as good thing about such the environment.
