If you could answer these questions and forward the answers to me to help start the design process.
- How long should be between charging batteries, once a day, twice a day, two days?
- Singlehanding needed?
- Shorttacking is fun
- The sole should be flat
- In light weather the boat should power if speed falls below 5 knots?
- Dining seats must be face to face?
- Galley should be out of traffic?
- Head area should be separate?
- All winches should be hand powered?
- Transom steps?
- Boat should be able to be beached?
- Kickup rudders?
- Shoal draft important?
- Unobstructed inside headroom is important
- Leangth of trips planned?
- Motor noise?
- Sea noise?
- Weight/cost tradeoffs
- Resale is important?
- Interior style? Old yacht-eurostyle-plastic boat style-mega yacht style
- Reefing gear type
- Frequency of anchoring intended
- Frequency of tacking and trimming intended
- Racing intended
- Helm should be covered from weather
- Good raingear is all that is needed
- Trimming quality verses helmstation comfort tradeoffs
- Most time under sail will be spent where?
- Most time at anchor will be spent where?
- Previous boats?
- Previous voyages?
- Previous races?
- How important is boatspeed?
- Boatspeed verses comfort tradeoffs
- Examples of best multi you have seen
- Examples of worst multi that you have seen
- Number of persons expected on most or typical voyages, and relationship of those people
- Most work will be upwind or downwind
- Rotating mast or not
- Fractional rig or not
- Fuel choice, why?
- Engine choice, why?
- How good should paint job be?
- Are there any other questions that i should have asked, but forgot to?
2 thoughts on “Sailing multihull preferences”
Hi Kurt, just looking at your site and thought I’d give my 2 cents worth and give my opinion on your list of questions.
Charging: 2-3 days
Single handing often
Short tacking not fun, but often necessary.
Sole should be near flat
We motor when boat speed falls below 3 knots
Dining seats must be face to face
Galley near dining area
Head area seperate
Winches manual except for halyards
10. Transom steps, for us NO, it’s a security issue for us in third world countries where theft is a common problem.
Kickup rudders, or dagger rudders, YES
Shoal draft, absolutely
Unobstructed headroom, yes
Length of trips, circumnavigation via 5 capes.
Motor noise sucks
Sea noise sucks too
Weight/cost, important and difficult to quantify
Resale important, yes
20. Interior style, less important than functionality
Reefing, slab and roller for jib
Anchoring, 95% if not sailing
Tacking and trimming, only when needed
Helm should have protection from weather
Raingear, see above
Trimming quality/Helm comfort is a tradeoff but comfort offshore is paramount, right after the ability to quickly dump a sail.
Most time sailing is offshore
Most time at anchor is in protected anchorages
30 Previous boat, Corbin 39, S&S 34
Previous voyages, 2 times atlantic to Europe, one time to Venezuela from Canada, Caribbean/Bermuda etc…
Races; Club races, rarely
Boat speed is important in light winds, average boatspeed over longer distances more important than sprinting to the finish line.
Comfort very important, Speed is second.
Budget is relatively small, less than $100 000 for hull/deck and another $100 000 to finish.
Best Multi I’ve been aboard, a friend’s self built Schionning 49, quiet and sails windspeed up to 12 knots true with a shorter rig than spec.
Worst multi I’ve been aboard, Endeavor cat
My wife and I sail alone across oceans and sometimes with guests while coastal cruising.
Most of our sailing is downwind, but upwind ability is extremely important to us.
Rotating mast, I’d like one
Fractional rig, yes
Fuel choice, diesel (rather electric but cost/repairability is an issue)
Formerly VW but on our KH45 will be yanmar, both for ease of finding parts and affordability of parts.
Paint job, should look smooth and clean, not necessarily mirrorlike and bright.
Missed questions… Many like keels, especially those who don’t mind losing a little speed. I’d love to be able to beach the boat (dry) and get to the hull bottoms for paint/repair. (I’m designing a removable shoe for the daggerboard slot so I can install before going aground for repairs or being hauled on the hard.)
I guess that’s it Kurt. Nice site.
Currently building KH 45 (stretched to 48 with your permission) in Canada.
