Set Sail on Adventure: "Opal" - A long-range small yacht
"Opal" is not your average Boomerang 20. This meticulously modified half cabin trailer sailer is a dream come true for those seeking adventure beyond the horizon.
Extensive Investment, unbeatable value: "Opal" includes countless hours of upgrades, all included at much less than cost price, or the cost of a new or large long range yacht.
**Built for Distance:
Extensive Cruising Upgrades: We've transformed "Opal" into a long-range yacht with capability for extended voyages.
Solar Power Freedom: Our high-quality Victron solar system generates ample power, keeping you off-grid and self-sufficient.
Unmatched Navigation: Navigate with confidence with a suite of top-tier Raymarine electronics, including a chartplotter, GPS, autopilot, and depth sounder.
Communication: Stay connected with a VHF radio with AIS receiver, and Cel-fi mobile signal booster.
Ample Storage & Refrigeration: The "Opal" boasts ample storage and we used two fridge/freezers (not included) to keep provisions fresh on extended journeys.
**Comfort & Convenience:
Weather Protection: The custom stainless steel bimini with solar panels and a versatile tarp system provides ample shade and shelter for all conditions.
Safe & Easy Boarding: The secure duckboard (swim/ platform) makes boarding and disembarking a breeze, also serving as a shower platform.
Amenities: Enjoy the comforts of a 12v & 240v electrical system, new mattress foam, back deck cushions, and a portable induction cooktop.
**Outboard and Safeties:
Low-hour Yamaha F15 4-Stroke Engine for reliable auxiliary power.
Safety Gear: EPIRB, bilge pump, fire extinguisher, and more ensure peace of mind.
