| Additional Illustration A18 Here's a simple, three views drawing that will probably clarify the approach with the boat design. I've also included a photo of the boat up on its side on the beach while I made a repair to the masthead halyard hook. There's a couple of published articles about the A18 at both the Watertribe site and at Duckworks Magazine. The articles will fill-out the design criteria I followed to produce the boat. http://www.watertribe.com/Magazine/Y...isOstlind.aspx http://www.duckworksmagazine.com/s/d...18-t/index.cfm Chris Ostlind  |

| Hey Raggi, Any sail boat I've ever been in that was planing, I could feel it was planing regardless of s/L ratios *S* . How's your studying with Mcnaughton going? Do you think it's worth pursuing? I guess I'm kind of cheap and want someone else to spend their money before I do to see if it's worth while. Take care Chandler |

| My studying is going very slowly because of work (paid work :-), kids, house and wife :-) I have read (some more) and done a few sketches for the exercises. Ask again in a couple of months maybe? |

| Another Wooden Trimaran Hi Lane, I haven't done any further work on the A18 as of today. I've been busy building a new canoe-based trimaran that is somewhat different from the full-tilt boogie performance potential of the A18. The new boat, the XCR, is 18'6" LOA has a canoe hull beam of 35" and is partially decked. It will be equipped for sailing with nice S&G amas with an overall beam of 10'. The sail rig will be twin, wishbone sprit boomed sails of 50 sq. ft. each. Total sail away weight will be less than 175 pounds. The boat was test paddled yesterday and it's a really nice canoe. It tracks well, turns on a dime (for a big canoe) and has high initial stability and a really solid secondary stability mark when it heels to the second chine. Oh, yeah, it's fast. I'm attaching a couple of images to show the new boat as it is so far and a rendering to show what it will look like when done. Chris Ostlind |

| A-18 tri Excellent little boat for beach cruising. Vast improvement for that purpose over a Hobie cat. Go just as fast without having to shift sides or get very wet. Also has dry place to store provisions. Do you think you'll ever sell plans for it? Did you design it for this years 'Duck Works' design contest? It could be a real contender. Bob |

| A18 Plans Hi Bob, Thanks for the kind words on the design. Plans will be available for the A18 in the very near future. I can't, in good conscience, submit the boat for a Duckworks prize, even if it could win the contest this year. And even that is a lot like taking a case to court... You never know what will happen once it goes to the jury. Ask OJ about that. I'm just about to introduce a web site for canoe, kayak and multihull sailing plans and hull kits. Because I'm on the threshold of doing it as a business, it pretty much would violate the spirit of the Duckworks credo and contest rules for submittal by amateurs. Besides, The head Duckworker, Chuck Leinweber, was in the boat for its first sailing test and it would be really hard to slip it past him without a case of something first. Chris |

| Muddle... Hello... I have been mucking around with a Messershmitt ME-109 styled trimaran with a single sail - most likely a Laser rig... Rgarding yours - how about moving the sails to the amas with a 'sheet bar' joining them like the Hobie Tri-Foiler... Keeps all the rig out of the canoe if you want to single or double paddle... Included some of my somewhat rip-offs...  - I like to call them studies...One is a drunken photoshop job and the other is another drunken photoshop job - seems to be a trend... How much would you retail your 18 for - do you intend a hardtop - removable hardtop - or a pipe and canvas bimini type thing... Also thought you might find the sunyacht proportions interesting... See http://www.ecocats.com/XP.htm ... Cheers - just some foggy thoughts... Nice bit... SH. |

| Yeah but... Hello... Only the first two are something I can lay a claim to - still formally rip-offs though... The SunYacht is from EcoCat... But heh - thanks... More drunken ripoffs and such - http://www.boatdesign.net/gallery/sh...00/ppuser/3673 ... Now back to CHRIS... SH. |
