Installation of an Arch

William Grobinson recently installed an arch on the stern of his C380 to mount solar panels and serve as a davit. Bill put one on his boat using the Atlantic Towers parts. http://store.atlantictowers.com/Sail_Arch_Accessories_s/1838.htm

Weaver Davits – Follow-up

Like the author of that article, after installing the Weaver davits I had a minor problem with the tail of my 8.5 foot dinghy dragging when sailing with a fair amount of heel. I had positioned the davits so that when sitting in the dinghy I could slide the the davit hoops on the dinghy right into the clips on the transom. This spring I raised the davit plates about a 4″, re-using the top holes in the transom. I can’t say for sure that this fixed the problem, but it wasn’t much of an issue in the first place. I’m sure this will be good enough. I don’t have a picture on my Picasa site that clearly shows the installed height of the davits. I’ll take a picture of the transom this weekend and post it with my other davit pics. http://www.catalina380.org/index.php/photo-album?wppa-album=5&wppa-cover=0&wppa-occur=1 Jeff C387 #145 I added a couple

Garhauer Dingy Davit Installation

Jim Turner, Makana Kai, 2000 C380 #227 Mainsheet February 2011 When we moved up from our Catalina 30 to a 380, the extra room and ease of boarding certainly made life easier for us, especially given our crew includes a 50lb Portuguese water dog. The two nice state rooms and ample salon means there’s even room for friends. This allowed me to justify a larger more stable RIB to carry all the people, pets, and supplies. While the 11’ RIB tows well, its bottom quickly fouls with growth if left in the water. I also don’t like hoisting a 120 lb. RIB on and off foredeck, squeeze around it, or trying to spot objects in the water over it. Towing the dinghy also overly complicates arrivals and departures, or docking, since we must reposition the dinghy often. My initial inclination that davits weren’t in our future dissipated quickly, and

Dinghies and Davits Go Together

Dinghies and Davits Go Together Bob Bierly February, 2008 Hull #: C380 #255 Recently, on the C380 sailnet site there have been several sessions devoted to the proper choice of dinghy and motor and the pros and cons of mounting davits for dinghy transport and storage. Simply put, like many other aspects of outfitting your C380, there is no perfect universal solution. What may be useful to cruisers are the following thoughts. Dinghies and Motors: The real issue with a dinghy and its motor is to identify their primary purpose. CASE 1 If, for example, you plan to cruise away from home, perhaps for lengthy stays (couple of weeks, months, even years), consider that your dinghy will be your basic local transportation. In this situation, I recommend that you (1) buy the largest, most stable dinghy (10 to11 feet) you can handle and, (2) obtain a big, reliable motor to

Caution- Davit Stress Corrosion

Caution- Davit Stress Corrosion Richard Herbst February, 2008 Hull #: C380 #93 According to Keith at Kato Marine (katomarine.com, 410-269-1218), earlier models of their davits were built using 304 stainless steel (including early 1998 when my boat, hull #93, was built). If they are continually stress-loaded (i.e., carry the dinghy all the time on the davits) while used in the tropics or similar climate, they may develop stress corrosion (i.e., cracking) of welded joints. If stress corrosion is evident, his advice is to have a qualified welder re-weld it and, in addition, add a gusset (about 1-inch triangular piece of filler metal) on each side of the broken weld. The gussets provide extra insurance against joint failure; it is impossible to know what is going inside the tubes by way of additional deterioration. For the same reason, Kato also suggested not drilling holes in the davits [eg: for wiring]. My

Davits Alternative – Weaver Davits

Davits Alternative Craig Spear February, 2008 Hull #: C-380 #273 A much simpler and much less expensive alternative are “Weaver” davits, whose description is included here to present a more complete picture of dingy storage. For a much more detailed description, refer to our section in the November 2005 Mainsheet; that article is also included on our Tech CD. –Warren I installed the eyes that attach to the side of my inflatable (RIB). The other half of the system is a pair of hooks that are mounted on the stern of my C380, just below the swim platform. To raise the dingy, first maneuver it to attach the two eyes on the dink to the hooks; then pull a line attached to the far side of the dingy, rotating it into the vertical plane with the bow and stern athwartships. (See Davits photo). The advantages include much less weight on

Weaver Davits

Weaver Davits Rick Beauregard November, 2005 Hull #: 160 What To Do With The Dink After another great weekend of sailing, snorkeling, barbequing, and general partying at Emerald Bay at Catalina Island, getting ready to go home is a drag. We start the routine around 11:30, to wait for the predictable San Pedro Channel trade winds to fill in. First, we retrieve and put away the flopper stopper, then I stow the Honda generator, and the eight horse Yamaha, haul the kayaks aboard, and uncover the main. Last but not least is the dinghy. I used to tow my 10 foot inflatable Quicksilver and take care of it when I got to home port. But I didn’t like the effect it had on my sailing performance. I hauled it aboard and laid it on the foredeck a few times, but up there it gets in the way and is a

Davits Follow-up

Davits Follow-up Marcia Ayres 5/1/2002 Hull #: 282 This is a follow-up on the February issue, which included an article by Ed and Sharyn Dahn describing their davits installation, among other things. They had found that additional bracing was needed, and had their own brace design fabricated. About two weeks ago, I received an emailed picture of another C380, also with Ocean Marine’s Davits installed. As this seemed to show an alternative method of bracing, I thought it would be of interest to all of you who may be considering installing davits. I contacted both Ocean Marine [Mike Thomas], and the owner of the pictured boat, Marcia Ayres, who was nice enough to provide a write-up on their installation. Warren- We bought the Ocean Marine Systems Davits after talking to Mike Thomas. He assured us that he had davits that would work on our boat. We discussed our needs as

Davits

Davits Ed and Sharyn Dahn 2/1/2002 Hull #: 111 We required davits for our Quicksilver 300 inflatable powered by a 15 HP Merc. After reading the C380 mail on Sailnet we ordered davits from Ocean Engineering. We had the same type of davits from other manufacturers on two previous boats and in the past there was some cutting, welding and a lot of fiddling. We ordered the Ocean Engineering davits specifically for our vintage 380 and also ordered all of the optional braces. Once installed, it became clear that the system as supplied would not work with the weight of our dingy. The stern rail deflected with load and the dingy would bounce around giving one the impression that the stern rail would permanently bend or break. Additional struts were required. The struts shown below were fabricated from stainless steel flat stock, 1” by ¼”. New Strut The lower end
