Greetings all, this is my first post and I'm hoping for some good info. I own my first boat. 1976 Irwin Competition 1/2Ton Mark ll. Said to have been built to IRC racing specs. The race for which this boat was built, is called the Half Ton Cup. And that is all that I know of her. I have sailed on her twice ....and now own it. I have been combing the net for info on this boat but have only found what is offered at the Irwin site. http://irwinyachts.com/Competition/IhalfT/Half%20T%20MkII.jpg http://irwinyachts.com/Competition/IhalfT/HT4.jpg .... good stuff but I'd like more. Loads of info on the Citation, but I cant find many people talking about an Irwin Competition Mark ll. And I have yet to see a single picture of one. I would love to talk with someone regarding the mainsheet configuration. Any info you might have on this boat or someone that owns and races one...... would be helpful. Thanks.
Ok, here are some pics of my new girl (I need to think of a name and fast....before I say anything more so stupid:)Any way drop the advise on moving the mainsheet. I dont want to effect the performance. Not anytime real soon, but I will be racing this boat someday. Barney,"I guess you know that the drawing you show the link to is another version (MkI ?? Only because the text states something about an outboard rudder)." ....Are you sure? Could be, for all I know. The diagrams I posted first have one window but beyond that they look the same. You are right, that diagram says "outboard" rudder but it is showing a pic of an "inboard" rudder ....so maybe there is a type-o. I can't find ANYTHING on a Mark1 to compare with. I'm going to make me a main sail here pretty soon... (yes I said make. I work in a loft) so I'll know my girl's "dimensions" soon enough. hmmmm. MyGirl .. maybe that's the name for her. I like Sha-Boom (my parents "song") or maybe Dream Weaver .... Any one care'ta vote? Or suggest? Again any info and for sure documentation anyone has on this make/model is very much welcomed. Please jump in. ps I dont see a way to move this post myself. Mods plz feel free to move to the IOR section.
Sorry for taking so long to respond. I've been super busy.The previous owner of the boat is a life long sailor, engineer friend of mine. I sailed 3 times before agreeing to his generous offer. She is in great shape. Maybe a little issue at the pulpit, but nothing that is spilling water inboard or showing any softness. Molded fiberglass with a plywood core is what it looks like to me. No signs of any major repairs and very little salon wood rot. All glass is good. Lines and forward hatch are crap. All the hardware needs TLC. Yes, dagger board. And SonoSail you were right about the E being shorter. What else do you know about that? P = 36.6, E = 9.35, leech 37.8 I guess there are any number of reasons for that. I'm hoping it's not a butcher job but maybe a redesign to control weather helm.I work for Doyle in Saint Petersburg. If more pics would help just let me know. I'm to busying getting it safe on a new mooring hook and "other" issues to do any sailing. But in a few weeks I'll have some pictures of her underway.
