The Keyhavenpotterers, Ed and dad Brian, had a wonderful day out in our Tirrik on Sunday. Blue sky, sparkling sea, nice warm 10 knot sea breeze. So you know what we're sailing she's an Oughtred Tirrik, 17ft double ender, slightly shorter than a Ness Yawl, 4 strakes. Occume on Sapeli. Sapeli fit out. Metal centreplate on small drum winch. Bermudan sloop rig with solid Douglas Fir spars. No extra ballast, but two of us (80-100kg blokes) in the boat so I'd guess she would be at her DWL. She's a good boat for a UK builder, as she fits in a UK garage. During our sailing season, just on some special days, everything goes just right and the summer appears, often when we are not expecting it. These special days last us long through the winter, remembering them and looking forward to new ones.
There's several video's of the Tirrik sailing along in the Solent if you click here:-
This was our third time out in the Oughtred Tirrik. Some observations so far:-
1. She's very good in waves. Taken straight on, a large powerboat wake just in front of us, she remained dry, all spray deflected out. The length of the boat and bow seemed take it very well, little pitching, and quite unaffected. She was better than my Tammie Norrie in this respect due to the extra length I guess for someone going further out. I guess the narow water line is good for cutting through and the reserve stability at the bow deflects things out. Also good with waves quartering or side on. She's good in that a nervous crew would find her motion reassuring. She's kinda floaty - like she floats along and over stuff, that your expecting to unsettle the boat, so you don't need to brace hardly. Healed over, there isn't much freeboard on the leeward side, and she's not got side decks (as drawn), so I wouldn't want to be knocked over, as she'd scoop water quickly, hence the reefing early protocol.
2. She pointed to 40 degrees perhaps off the wind, perhaps 30 dehrees to the apparent wind. She certainly felt like she pointed high like a good bermudan sloop. What was surprising was that she pointed very well without a profiled centreboard or rudder. The centreboard on her is a flat steel plate and her rudder is flat accross the chord. Its not scientific, but we've had many dinghies and boats, but I'm surprised by the performance of that simple metal plate, and I'm wondering if its worth building profiled centreboard's in practice now. For someone wanting the extra stability of a metal plate and to save building time, I don't think there's any loss of performance noticable to a cruising sailer. I know, I've read all the technical stuff, NACA profiles, the lot, just in reality, with a narrow metal plate she was pointing high (higher than a 420) and going at the same speed in light airs. I'm just sayin, metal plates seem to work actually very well. Two metal foils and cheap aluminium tube spars for a boat, saves alot of time potentially and make building very time efficient. If anyone says metal plates don't point well, I'm afraid I don't believe them. They do in practice.
3. We got some Harken blocks on her a 6:1 on the boom downhaul, a 4:1 on the kicker and mainsheet and they were a big improvement, and the sails adjusted real easy. Spliced dyneema for the control lines, and some Maffioli Swiftchord on the mainsheet (dyneema core with a grippy non kinking outer). I know its not done by everyone, but the Harken mainsheet with a cleat, makes sailing while drinking and eating alot easier. Sitting on a spare memory foam cushion is also a pleasure for one's bottom.
4. The sails were by R&J in the UK. We've got the invoice from the sail maker with the boat, for the jib and main and these are very good value indeed. They are in cream dacron, nicely sewn and have bronze hanks on the jib and sewn leather wear patches - nice details. Its sometime good to use a local sail maker, to discuss things and look at the spar bend etc to the sails are cut right, but these were great and good value and nicely made and suited the spars - definately a big thumbs up for R&J from us. It says they use Contender sail cloth which is good stuff.
Here's our sails, just need some tweeking, easing the leach line and the outhaul https://picasaweb.google.com/Brian.A...28545814466514
Note they do a novel batten roached main on their Drascombe range of sails...
