Traditional wooden vessels offer 4-8 cabins with crew, but specialized large group gulet charter options accommodate 15-30 guests comfortably. The largest gulets are 40 to 50 meters long and have 10 to 12 cabins. Most group charters use several boats or book very large single vessels. These vessels have more than 8 double cabins and special crew quarters.
Many operators won't share this right away: booking one large gulet for 25 people usually costs more. It also offers less flexibility than renting two medium-sized boats. We've seen this play out countless seasons along the Turkish Riviera.

Understanding Large Capacity Gulets
A gulet for 20 people usually has 8 to 10 cabins with their own bathrooms. It also has large deck areas that are 15 to 20 meters long. The crew has their own quarters, separate from the guest areas. Standard Turkish gulets max out at 16-18 guests legally, but purpose-built charter vessels push this to 24-30 with proper licensing.
The capacity confusion comes from passenger vs. charter regulations. Day-trip gulets legally carry 40-50 people but offer zero sleeping comfort. Charter gulets prioritize overnight accommodation, limiting realistic capacity to 2-3 guests per cabin maximum.
Here's what charter seasons reveal about group sizing: families of 15-20 consistently report better experiences than groups pushing 25-30. The sweet spot sits at 18-22 guests where deck space, water toys, and crew attention balance perfectly.

Size Categories and Capacity Breakdown
| Gulet Size | Length | Cabins | Max Guests | Best For |
|---|---|---|---|---|
| Standard | 20-28m | 4-6 | 8-12 | Extended families |
| Large | 28-35m | 6-8 | 12-16 | Multi-family groups |
| Ultra | 35-42m | 8-10 | 16-20 | Corporate events |
| Mega | 42m+ | 10-12 | 20-30 | Reunions, celebrations |
Ultra-category vessels dominate the luxury gulet charter market for groups. These beautiful boats are 35 to 42 meters long.
Gulet Charters for 15-30+ Guests
Traditional wooden craft with 10+ cabins. Private crew and authentic hospitality for your entire group.
They have 300 to 400 square meters of deck space. There are many dining areas and top-quality water sports equipment. Captains report these handle 18-20 guests far better than cramped 24-person configurations.
The mega category exists but remains rare. Only 15-20 vessels in the entire Turkish fleet genuinely accommodate 25-30 guests with proper comfort standards. Most operators advertising "30-person capacity" mean day trips, not week-long charters.
Cost Structure for Large Groups
High season rates for large group gulet charter run €15,000-€35,000 weekly depending on vessel size and luxury level. This costs between €750 and €1,750 per person for groups of 20. This is much cheaper than booking individual cabins or staying in hotels.
Peak July and August pricing hits maximum levels:
- 8-cabin gulet (16 guests): €18,000-€25,000
- 10-cabin gulet (20 guests): €25,000-€35,000
- 12-cabin gulet (24+ guests): €35,000-€50,000
Shoulder seasons in June and September slash these by 25-35%. We've seen identical vessels drop from €28,000 in August to €18,000 in early June. Smart groups book September when water temperatures still hit 24-26°C but crowds disappear.
The pricing surprise? Food and beverage costs for large groups typically add €80-€120 per person daily.
A group of 20 people spending €2,000 each week on food seems okay. But if you look at the yearly cost, it adds up to €28,000 if you charter monthly. Budget accordingly.

Single Vessel vs. Multiple Gulets
Chartering two gulets together solves many large group challenges while creating new ones. Two 8-cabin vessels (16 guests each) cost €30,000-€40,000 combined but offer flexibility one mega-gulet can't match.
The advantages stack up quickly:
- Separate family spaces reduce friction
- Different activity preferences work better
- One gulet handles engine issues without stranding everyone
- Racing between vessels adds entertainment
Coordination becomes the headache. Captains must communicate constantly, moorings need double space, and restaurant reservations require splitting groups. Routes we've run show this works brilliantly for 24-30 guests but feels excessive for 16-20.
Groups of exactly 20 people face the toughest decision. One 10-cabin gulet keeps everyone together but feels tight. Two 6-cabin vessels (12 guests each) waste capacity and budget. This explains why 18-22 remains the magic number—it fits comfortably in one large vessel.
Best Routes for Large Groups
The gulet cruise experience changes dramatically with group size. Standard 7-day routes from Bodrum or Fethiye work differently when 20+ people need bathroom access, swimming time, and shore excursions.
Popular large group itineraries include:
Bodrum to Gocek (7 days): Covers 80-100 nautical miles with stops at Knidos, Datça, Ekincik, and Tersane Island. Large gulets handle this route easily with 4-5 hour sailing days and protected anchorages fitting multiple vessels.
Fethiye to Olympos (7 days): Pushes east along dramatic coastline visiting Butterfly Valley, Kas, and Kekova. The 120-140 nautical mile distance suits groups wanting more sailing experience and fewer crowded bays.
Greek Islands extension: Adding Symi Island or Kos requires advance planning for 20+ guests. Customs processing takes 90-120 minutes for large groups versus 30 minutes for small charters.
Worth it? Absolutely. The crystal clear waters around Symi beat anything in Turkey.
What most guides miss: large groups should avoid ultra-popular spots like Cleopatra's Bay during high season. A 40-meter gulet anchoring in a 200-meter bay filled with 15 other boats creates chaos. Experienced captains know alternative anchorages offering similar beauty with half the traffic.
Booking Timeline and Strategy
Book 8-12 months ahead for July-August large group gulet charter departures. The limited fleet of genuine 20+ person vessels fills by February for peak season. We've watched groups scramble in May, settling for two smaller gulets when they wanted one big vessel.
Early booking advantages beyond selection:
- Negotiating power drops 40-50% after March
- Preferred routes get claimed first
- Crew quality matters more for large groups
- Deposit schedules favor early commitments
The controversial take: don't book ultra-early for shoulder season. Prices often drop 15-20% in the 6-8 weeks before departure as operators fill empty slots. This works for flexible groups but risks losing specific vessels.
Payment typically splits 50% deposit, 50% final (30-45 days before). Large group bookings sometimes negotiate 30/30/40 splits to ease cash flow. Never pay 100% upfront regardless of "discount" offers—standard industry practice protects both parties.

Cabin Configuration Strategies
Eight-cabin gulets usually offer 4 double + 4 twin configurations, but groups of 20 need creative arrangements. Master cabins fit couples, twins handle kids or singles, and convertible saloons accommodate overflow.
The reality check: advertised capacity assumes maximum occupancy. A "20-guest gulet" with 10 cabins means couples in every room. Groups with 8 couples + 4 singles face awkward arrangements. Plan actual sleeping needs, not theoretical capacity.
Smart configurations we've seen work:
- 6 couples + 8 kids in twins = perfect 20
- 4 families (4 people each) + 4 singles = comfortable 20
- 10 couples = maximum 20 but tight on deck space
Children under 12 often bunk together happily, freeing cabins for adults. Teenagers? They'll want separate spaces, complicating layouts. Factor this into vessel selection—extra cabins beat cramped arrangements every time.

Crew Requirements and Service
Large group gulet charter demands bigger crews. Standard ratios run 1 crew per 3-4 guests, meaning 20 passengers need 5-7 crew members (captain, cook, 3-5 deckhands/stewards). Mega gulets add specialized roles like pastry chefs or activities coordinators.
The service difference becomes obvious at mealtime. A cook preparing meals for 12 handles everything smoothly. The same cook feeding 24 needs kitchen help or guests wait 90+ minutes between courses. Quality operators staff appropriately; budget ones stretch crews too thin.
Water sports supervision matters more with large groups. Two jet skis, paddleboards, and snorkel gear need coordinated management when 20 people want simultaneous water access. Understaffed vessels create bottlenecks and safety concerns.
Activities and Entertainment
Traditional sailing on gulets accommodates groups beautifully. The spacious decks, multiple lounging areas, and stable platforms handle 20+ people better than motor yachts. But activity coordination requires planning.
Water toys for large groups should include:
- 2-3 jet skis (eliminates wait times)
- 8-10 paddleboards
- Snorkel sets for everyone
- Inflatable platforms for swimming
- Kayaks or canoes

The equipment surprise: most gulets include basic gear but charge €500-€1,500 weekly for premium water sports packages. Groups serious about activities negotiate this upfront or bring their own equipment.
Shore excursions get complicated. Historical sites like Kekova's sunken city or Knidos ruins handle small groups easily but 20+ people need advance coordination. Split into smaller parties or book private guides—showing up with 20 people expecting immediate access rarely works.
Common Pitfalls and Solutions
Groups pushing maximum capacity consistently regret it. That "sleeps 24" gulet feels crowded by day three when everyone's onboard simultaneously. Build in capacity buffer—book for 24 if you're actually 20.
The bathroom math nobody mentions: 10 cabins = 10 bathrooms, but morning rush with 20 people creates 30-40 minute waits. Stagger wake times or accept the reality of shared spaces during peak hours.
Weather impacts large groups differently. A small gulet easily relocates when wind picks up. A 45-meter vessel with 25 guests aboard has limited alternative anchorages and higher fuel costs for repositioning. Flexible itineraries matter more for big boats.
Food preferences multiply with group size. Eight people agreeing on meals works fine. Twenty people include vegetarians, allergies, picky kids, and adventurous eaters. Discuss dietary needs exhaustively during booking—surprises onboard create tension.
Worth Remembering
Large group gulet charter delivers unmatched value for 15-25 travelers when properly planned. The per-person cost beats resort vacations, the privacy exceeds hotel experiences, and the flexibility allows customized adventures. But success requires realistic capacity planning, early booking, and understanding that bigger isn't always better.
Groups of 18-22 hit the sweet spot where one vessel provides intimacy without crowding. Push beyond 24 and you're essentially running a small cruise ship with all the coordination challenges that implies. The turquoise waters and sailing experience are magical no matter what. Just choose a boat that fits your real needs, not just its potential.
