3 Presentation Format “What is a Quarter Tonner”? Project 1 ‘Bandit’ Project 2 ‘Per Elisa’ – How/where do you find a Good Quarter – Have the Boat – what next? – An ‘Average Quarter Tonner” approach to decision making. – Piecing it all together Rig Sail Area Keel Boat Building Costs Conclusions

4 immediate Igor

5 WHAT IS A “QUARTER TONNER” ? International Offshore Rule 24-27 feet long 1300 kgs to 1700 kgs Crew of 5 Trailor sailor-able Budget to suit all tastes Modified in recent years Proper little boat

6 What makes a Good Quarter tonner! A relatively long boat- Average size is 7.7 m... Big is beautiful! Hull Speed =1.34 x Sqr Root of LWL Fast = 1.34 x Sqr Root of a “Long boat” Weight- An all up weight of 1400kgs approx. Pedigree- it should be easier to make a fast boat faster! Non-exotic construction. (HF) Simple rig plan Powerful sail plan Stability Doesn’t have to be but she should look nice! Note: HF is Hull factor and is a significant component of the IRC rule. In broad strokes it is the rules way of penalising boats which are stripped out/ ‘non cruisey’ or made from an exotic material- Kevlar/ Carbon composite etc. Google Hull factor + IRC rule

7 A PROPER BOAT WITH PERSONALITY!

9 QUARTER TONNER REBUILD PROJECT How big is too big! Peter Morton’s ‘Bullit’ QTC winner June 2012 Bullit in Feb 2012 Bullit in Feb 1980

10 THE BANDIT PROJECT Modified Bolero 25 Production QTer Photo Credit- Bob Bateman

11 OPTIMISATION PLAN Removed some interior- primarily from the ends. (Weight) Worked out upwind and downwind SA’s Built in new chain-plates for new swept-back single spreader Rig. Full aesthetics refit. Bottom fairing “Designed”, cast and fitted lead shoe. (70 kgs) Found a second hand mast to fit the bill! With the help of some friends found the right place to stick it in the boat! Note: From memory, the mast went aft about 200mm. This is a must if you go for a non overlapping sail plan as it helps maintain balance.

12 Fun Boat Very competitive record. Very economical to run. Great resale potential

13 Along came a Tiger!

14 PER ELISA PROJECT CUSTOM QUARTER TONNER CECCARELLI 1992

15 Where do you find a good Custom built Quarter tonner?

16 ciao, spero che tu sia ancora tutti svegli!

17

18 Have the Boat- What next!

19 Engine removed. All Qters now gone to outboards.. No prop drag and permits an heavier keel. Significant reinforcing to bilge/floor reqd for heavier keel.

29 RIG CONSIDERATIONS Single or double spreaders? How many halyards? Halyard locks or not? Where to stick it into the boat! Structural considerations for new mast position. How big or small- The average QTer approach P9.759.979.74109.899.999.75 9.749.84 E3.413.93.433.563.5 3.41 3.453.51 J2.712.432.852.932.85 2.8 2.752.77 FL9.969.949.6110.2210.1210.339.96 10.01

30 SAIL PLAN Starting Point Espada (QTC Winner 2011) Probably a little too big as Per Elisa: Is smaller in volume terms than Espada. Has a more slippery hull form Design Ratios SA:D Av SA/D Upwind = 28-30. (32) AV SA/D Downwind = 50. (51) Easier to cut a bit off than........ Personal preference Hate being underpowered!

31

32

33 Keel Considerations Stability = power. Again look at the weight distribution slide, the overall weight of the boat did not change, just the distribution. Sail area, the upwind remained pretty much the same, but the kit went from 32M² to 45M².......which is a HUGE % sail area increase.

43 Note: Quick adjustment forestay. We adjust 12 turns from fully on to fully off, depending on wind. No spanners reqd. Note: Athwartships jib tracks. Reason being the LP on non-overlapping jibs does not vary so much so there is very little adjustment required fore/aft. The in/out adjustment allows for better sail shape control when the sheet is cracked. (No need for an outboard lead to control the leech twist). Note: Halyards run below decks.

47 Conclusions Whatever the scale and scope of a rebuild project they are fun. Sail as is or DIY, professional refit or a bit of both. While daunting both these projects were very satisfying in terms of; A great sense of achievement Develops ones boat building skills Improves ones boat prep’ing skills Understand IRC better Generally meet great people. Very Competitive Class. Excellent Class camaraderie. Crew of 5 Trailer-sailor Budget to suit all pockets. A FUN easy & pretty boat to sail, crew, trail, store, and maintain!
