Howdy Folks
This is my first time to ever post on the WBF, (or any forum for that matter) so if I commit social forum phopa be gentle with me! So here is my story....in 2003 I bought a beautiful classic one off full keel wooden sail boat, carvel planked Alaskian Yellow Cedar on steam bent white oak frames, with Austrialian gum deadwood, DougFir keel, Blue Spruce spars, teak over ply decks, ipe cap rails and stanchions, mahogany interior etc. 17,000lbs ballast (14,000lbs iron punchings and 3,000lbs of concrete) 2 tons of which was internal. So it was love at first sight for me when I went to see her for the first time and then taking her out for our first sail, well let's just say She spoke to me! Any way we (myself, wife and daughter) bought her, moved aboard and started living and cruising full time. The survey, when we bought her said that there were 6 cracked ribs but that they were not bad enough to worry about but keep an eye on them and if they get bigger then repair them. In 2006 we were sailing south on the pacific about 125 nm off shore running from the mother of all storms, it fought up to us at about the 42nd latitude. without boring you with a lot of blow by blow details, I tell you that I spent 28 hours none stop at the wheel, we were doing 14.2knot under bare poles before I took measures to slow us down. We took a tremendous pounding. Rising over waves that were higher then our mast the boat would fall off with such force it tore out most of the cabinets in the boat! The 49,000lb test shakle on the bobstay shattered, I consider myself really blessed that the rig did not come down. Anyway more sea miles a few more storms and a few years later and I hauled out in Nicaragua to replace some planks that got toredos above the bottom paint #%^*+ (mental note raise the boot stripe) redo the bottom paint change the zincs, general maintenance and replace the garb'd that had started to leak. Well when we pulled off the first plank we found every single rib we uncovered Was broken!!! Pulled more planks ...more broken ribs!!! Some broken in 2 and 3 places, all on the hardest part of the curve. I pulled the garb'd and the base of all the ribs where they mortised in to the keel were desiccated away. I decided that I had to replace every single rib. So I waited till the rainy season was over and then hired a old local shipwright (73yrs old) named Juan to work with me and together we plowed into the project. I decided not to go with steamed bent ribs and to double the size of the new ribs, and make them out of Laurel. I hired a wood cutter and he and Juan went into the hills where Juan could show him the curved trunks that would work for making grown ribs. We could get between 4 to 8 ribs to a tree trunk. And for all the traditionalist out there we cut every one with a hand saw and an assortment of adz. Juan can work me into the dirt with an adz. So far we replaced all 128 ribs, I found rot in the 15' long keel horn, we replaced that with Cortez ( Ipe) and we have replaced all the floors with Ipe as well. The deck was teak over ply, of which we discovered that a lot of the ply was bad and had spread rot into the fore deck beams. (a previous owner had done an ugly repair job on several spots on the deck and then painted some sort of thick rubber bumpy coating on the teak sealing it all in and that had allowed blisters of rot to form undetected till they were huge!) We have replaced all the quarter deck beams even though they were good because I it to eliminate the dog house, and now I have an open quarter deck. (one of the modifications I have been planing for a while, a much safer platform to work on the mainsail and a great place to hang out at anchor).
So here is where I can use some help....Nicaragua has some fantastic woods used in boat building. Here is a list of some that are available to me. I'll list them, common spanish name / english name (scientific name) family name.
Caoba /......(Swietenia macrophylla King.) Meliacaea
Cedro macho/ Royal Mahogany(Carapa guianensis) Meliacaea
Cedro real/ ...(Cedrela odorata L.) Meliacaea
Tamarido/ ....(Dialium guianense Aubl.)Caesalpinaceae
Cortez/ Ipe (Tabebuia guayacan Hemsl.) Bignoniaceae
Guanacaste de oreja/....(Enterolobium cyclocarpum Griseb.)Mimosaceae
Guapinol/ Brazilian Cherry....(Hymenaea courbaril L.) Caesalpinaceae
Guayabon/....(Terminalia amazoniaExeli.) Combretaceae
Guayacan/....(Guaiacum sanctum L.) Zygophyllaceae
Jagua/...(Genipa americana L.) Rubiceae
Kerosan/...(Tetragastris panamesis O. Kze) Burseraceae
Laurel/Laurel...(Cordia Alliodora Ruiz) Boraginaceae
Leche Maria/....(Symphonia globulifera L. f.) clusiaceae
Santa Maria/...(Calophyllum brasiliense Camb.) Clusiaceae
Mora/...(Clorophora tintoria L.) Moraceae
Nacascolo/....(Caesalpinia coriaria wilid.) Caesalpinaceae
Nambaro blanco/...(Aspaidosperma megalocarpon Muell.) Apocynaceae
Quebarcho/...(Pithecellobium arboreum L.) Mimosaceae
Roble/...(Tabebuia rosia D. C.) bignoniaceae
Sebo/...(Virola koschnyi Warb.) myristicaceae
Teca/ Teak...(Teciona grandis) verbenaceae
So do any you folks out there have any experience with any of these on your boat or in your shops. Good results or bad. I was thinking of using teak or Santa Maria for the hull planks.(Pardey in his book Hull Construction says that you can add 20% to the boat value if you plank in teak.)Brazilian cherry for the king planks and deck edging (10' wide) and the deck itself with teak. Caoba for the stanchion and roble for the gun'l cap rail.
Thanks for any input and now I'll try to down load some pictures of what I'm doing.....Capt. Zatarra
