Sailors,We've all seen this question asked and discussed a hundred times. Me too. However, in my experience, I've never seen anyone ever try to quantify or support their rationale in any meaningful way. Which eventually got me thinking "How would you go about quantifying and supporting your preference?" Here's what I came up with to frame and answer that question.There are at least four major areas to consider (more or less if you want to split hairs, I don't). They are 1) Cost, 2) Performance, 3) Comfort & Safety and 4) Complexity/Simplicity (all explained in the 'Baseline Data & Assumption' list below). BOTTOMLINE: 1. Money $$ is going to be the most important driver in 2/3rds (67%) of the total number of people making the 'size' decision. Which means the majority of the sailors will have to choose less a boat than 42 feet right off the bat. This closely matches the size survey that was recently conducted on this website too.2. Performance wise (speed), you are only arguing over roughly a ~1 knot difference between the speed of a 30 foot boat compared to the same type 45 foot boat.3. Comfort & Safety only marginally improves as size increases and is somewhat subjective.4. Complexity/Simplicity is mainly subjective.So, what is YOUR opinion on the best size cruising boat now? This purely an academic excercise in hope of narrowing this subject down. If you decide to reply, try to support your answer with something tangiable. I like a good arguement but, don't want to argue over semantics. If you are offended somehow? Which happens all the time on these message boards. Know upfront that it wasn't my intent or purpose and I suggest that you, "Don't reply to this message". Regards,James ************************* Baseline Data & Assumptions ***********************1. Cost & Quality:The mean National Income in the USA last year was about $67,000 per family. Less than ~15% of the nation’s families bring in more than $100K a year.It will cost a minimum of ~$100K to purchase a Used Sailboat >42 feet long that is less than 20 years old, while still being in decent shape. It's assummed that you'll pay more for a higher quality boat at a given length. Which doesn't lower the price below $100K.Maintenance & Slip costs look like they will run ~10% of the purchase price of your boat per year. However, new boats maintenance will be less, older boats more, thus averaging out some where close to that figure.2. Performance:Sailing Speed (Hull): The best way to make my point about sailing speed is using a sample (market basket) of boats from 30 feet to 44 feet. Catalina ‘30 = 6.7 kt.Jeanneau Sun Ody. ‘34.2 = 7.3 kt.O’day ’37 = 7.4 kt. Hunter ’40 = 7.6 kt.Beneteau 440 = 8.1 ktAuxiliary Engine Speed: Max cruising speed (not full speed) looks to be around 7 knots regardless of the boat size. No surprise given the design parameter for sailboats looks to be around ~3.5 Hp per ton.3. Comfort & Safety:Motion Comfort: (theoretical value > # is better): Again the best way to make my point about sailing speed is using the same sample above.Catalina ‘30 = 24.73Jeanneau Sun Ody. ‘34.2 = 21.62O’day ’37 = 26.76 Hunter ’40 = 24.96Beneteau 440 = 24.12Sleeping Berths: At a minimum you can count on getting this number of sleeping berths at these boat lengths. The intent is just to ‘goal post’ the possibilities within the discussion extremes. 26 feet = 4 berths45 feet = 6 berths Aesthetics: You basically get more room and more potential for additional features as the size of the boat grows. The theory behind this is that you are not going to deliberately make yourself miserable.Safety: Without a doubt a bigger boat will be safer boat than a smaller one of the same type. HOWEVER!, given the fact that we're only talking about a maximum difference in length of 15' (i.e. 30' to 45'), it won't be a significant factor in this discussion unless you are comparing the boats at the two extremes. 4. Size and its correlation to “Complexity vs. Simplicity” (and Vive versa):This is the only area that will become somewhat subjective and more dependent on your own perspective. For example: I could argue that with an Auto pilot, furling headsail and all sheets & lines leading back to the cockpit, I’ve “simplified” things to the point that I can now sail single handed. However, I paid for this simplicity with the help of several “complex” sub-systems and needed additional “space onboard” to install and maintain them. You can make similar arguments with any combination of systems below; however, my intent is to simply identify this area as a potential question in the overall size of the sailboat issue (i.e. bigger boats can hold more of these things too).Typical onboard sailboat systems GeneratorsAuto PilotsSSB RadioVHF RadioInvertersRefrigeratorsWater HeaterPressurized WaterBilge pumpsAC PowerRigging (Line layout, sail furlers & Etc.)BatteriesRadarGPSGauges (compass, speed, wind, & depth)LoranAnchors & Ground tackle
