Many factors contribute to the selection of a yacht. At the root of any sound yacht purchase decision is the core performance factors that are essential to consider long before you review interior decoration or layout.
- Motor or Sailing yacht
- High-speed performance, Semi-planing hull shape or slow full displacement?
- Size restrictions: Will you need access to a location with draft, beam, length or height restrictions? Does the dock behind your home have X feet of available water or a fixed bridge limiting access to the yacht with an air draft of less than Y feet?
- Guest carriage requirements: Number of guests cruising onboard and sleeping onboard?
- Maintenance issues: Are parts readily available in the intended cruising areas?
- Crew: Will the yacht accommodate a suitable number of crew to match your service expectations?
- Range: Where in the world do you wish to travel? If those ports are not serviced by a yacht transport service then the yacht will need to have an ocean passage making range and hull shape.
- Full-displacement vs. Semi-displacement?
The pros and cons of semi-displacement compared to full-displacement are:
|Speed||18-25 knot cruising speed||10-12 knot cruising speed|
|Fuel Consumption||Very high fuel consumption. Often four to six times the fuel consumption of a similar-sized full displacement yacht.||Fuel efficient when compared with a semi-displacement.|
|Transatlantic passages||Not self-powered, but possible using yacht transportation at a cost of $850-$1,200 per foot each way.||Capable of self-powered transatlantic passages. Costs range from $250 to $600 per foot depending upon crew size and engine size.|
|Engine Maintenance||Specialist engineering. High powered engines require more maintenance from outside companies and specialists.||Lower power rating and crew engineers should be capable of maintaining 95% of all engineering needs.|
|Stability / Comfort||Hard/fast roll due to hard chine hull shape.||Slow roll. Generally more comfortable at anchor.|
|Volume||When designed initially for speed semi-displacement models generally have the shallower draft and less interior volume than full-displacement models of the same length.||Volume considerations have less impact on performance so hull shapes generally contain more interior volume than the similar length in semi-displacement.|
|Noise||Generally louder interiors whilst underway due to desire to reduce weight in construction and larger engines and faster water movement.||No restriction on build weight allows full implementation of noise attenuation. (not all manufacturers employ the necessary construction to minimize noise).|
