I'm looking for pictures and information about dinghy davit systems that can be used on a Catalina 42 without hitting the backstay.
We are doing more long distance cruising and davits would be a big help!! Thanks Roger |

Roger,
Unless the davit arms are really long, virtually all systems will pull the dinghy up against the transom and the backstay when the dinghy is just coming out of the water. At the same time, almost any system can hold the dinghy well back from the backstay when the dinghy is raised. Most manufacturers have more than one davit arm length available. The best choice depends on how you plan to mount the arms. In general it is best to go with a system that will position the dinghy properly when raised, and simply live with the small interference from the transom and backstay when the dinghy is near the water.

Roger: If you find a set of davits with long enough arms to stay clear of the backstay, you will have a difficult time securing your dingy (side to side motion) while sailing. I have found it's better to have it close to the transom, so it can be secured. CAUTION! Constant rubbing on the back stay when raising and lowering could puncture your dingy, so you will need to figure some protection. My radar is mounted on my backstay, so the 3 in diameter pipe over my backstay all but eliminates that problem.

I installed a plastic sleeve on the lower portion of the backstay to give the dinghy a smooth surface to ride when being lowered or raised. I believe it is made of nylon and available at West Marine.
You should also search the forum for there are many long threads on dinghy davits, options, securing the stern rail, etc. Tino Lanza, Dancing Dolphin (#739/3 cabin pullman, Westlake Village, CA)

Tino is right, that is a pretty popular topic. Much of the discussion can be found in the archives. You should go to the JUMP TO pulldown on the bottom of most pages. You will see Dinghy-Davits there.

I just came back from the Annapolis boat show where I spent some time looking over Garhauer,s davits , they are a work of art , and the price is great ,
I have searched these archives and can,t find any pictures of garhauer's installed on a C42. Does anyone have pic's that they can post or Email me? Dave Zeuli dbnonsense@aol.com Common Sense #810 |

I added the Garhauer davits to Merlin (823, MkII) this spring. They are a fine product at a very nice price. The weight of the 11'2" inflatable w/air floor and 6 horse Mercury caused the stern rail to flex excessively under way. I called Mark at Garhauer and they made a set of struts. They mount diagonnally from the top of the stern rail just outboard of the ladder opening down to the swim platform. They make great grab bars for getting on/off as well. Care has to be taken to limit the travel restriction on the platform lockers of course. Send me an email at vailte@msn.com if you would like photos.

While our davits are Kato Marine, the attached photos may be of help.
www.catalina42.org/photos/davits.jpg You will see the plastic backstay cover that permits smooth raising and lowering of the dinghy without fear of puncturing the tubes. You will also see three rail support bars, two on the side with the engine and one on the dinghy bow side. My guestimate is that 80% of the weight is carried on the engine side. The second support bar is kinked just enough to permit the port transom locker to open. Thirdly you will see the stern light mounted on the cross brace. Since the picture was taken I have also relocated the GPS antenna to the cross brace. We use straps to secure the dinghy while under way. These criss cross to prevent side to side motion without having the dinghy tubes rub against the davits. Lastly we have a dinghy cover that safeguards against a rogue wave filling the dinghy with water causing the whole system to fail.

Garhauer will make davits to your specs. I had them make them 42" rise and 42" reach. It seems to work well for my 11' RIB 15 hp dingy. My boat had Kato supports from the stern rail to the sloped tramsom, the stern rail definitly needs support.
I would remove the engine for rough weather, but I added a wire rope support from the engine davit end to the backstay (@20' up). This has worked for normal sea condition. Also, add a length of pvc over the backstay. The dingy will ride up the pvc, but it is clear once it reaches the top. Guarhauer davits are solid, with 6:1 tackle included. They worked to meet my deadline and I highly recommend them. Tropical Itch 1991 2 cabin |

SECURING DINGY to Davits for No. Calif Coastal Cruising #2
http://images.yuku.com/image/jpeg/d21352ef7420d48b0598d4b82ebd9bcf075cedc.JPG http://images.yuku.com/image/jpeg/0d525157bbd6400fd97252afcd5ea60e9ae002a.JPG http://images.yuku.com/image/jpeg/5c935d2b7355debb0618d88228aedb1837b1d1b.JPG http://images.yuku.com/image/jpeg/32015276d305d324b0d994904f77549d54e5836.JPG ********************************************************* With all the words on davits posted here I thought these pics may help on firm securing a 10.5' inflatable properly to a Kato Davit System. 1.) The dingy must be secured via two separate dingy lifting cables rigged (a) from port to starboard forward lifting rings on the tubes and aft (b) on the transom near the dingy floor aft. Fashion these to lay tight and as close to the dingy floor as possible in order to raise dingy high enough (with the lifting block and tackle units) to nest securly against the lower strut of the davits. THIS IS WHERE MOST CAPTAINS MISS THE MARK ON SECURING THEIR DINGY FOR SEA TRAVEL! thus having the dingy sway to and fro and side to side in a seaway. (I created both of these from short flexible rigging steel cables to a central 'O' ring (they lay almost horozontal to the floor!!!!without slack!!!).....this is MOST important to gain a secure hold on the dingy thus helping to minimize any movement when at sea) 2.) Use nylon straps (from Kato) with Stainless Steel rachet blocks to tighten dingy securly to the mothership. (twisted before inserting in the rachet...to keep from vibrating in wind). These can be seen in the pictures and connect inside the dingy and lay over the aft facing tube run under the dingy and connect in crossed fashion to the stern pulpit. THESE STRAPS ARE A MUST TO KEEP THE DINGY FROM MOVING FROM PORT TO STARBOARD IN A SEAWAY! Hope these help Tom Charron MIVIDA #631 |
