The Beneteau First 45F5 1990 vs Beneteau First 50 Standard 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - Beneteau First 45F5 1990 at 46,7 ft versus Beneteau First 50 Standard 2006 at 49,2 ft. Weight tells a clearer story for trailering families: the Beneteau First 50 Standard 2006 tips the scales at 29 950 lbs - 6 801 lbs less than the Beneteau First 45F5 1990 at 23 149 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 75 hp, the Beneteau First 50 Standard 2006 has a 25-hp advantage over the Beneteau First 45F5 1990's 50-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau First 50 Standard 2006 carries 63 gallons versus 42 gallons in the Beneteau First 45F5 1990. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Beneteau First 50 Standard 2006 is rated for 15 passengers, while the Beneteau First 45F5 1990 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 50 Standard 2006 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau First 50 Standard 2006 displaces 29 950 lbs - a 6 801-lb difference over the Beneteau First 45F5 1990 at 23 149 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.
Both boats draw a similar depth - 7,1 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First 45F5 1990 uses Sloop rigging. Helm style differs too: the Beneteau First 45F5 1990 uses a 1 wheel versus a 2 wheels on the Beneteau First 50 Standard 2006. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau First 50 Standard 2006 carries a 75-hp engine against 50 hp on the Beneteau First 45F5 1990. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Hull speed is rated at 8,8 knots for the Beneteau First 50 Standard 2006 and 8,1 knots for the Beneteau First 45F5 1990. For extended cruising, water capacity matters: the Beneteau First 45F5 1990 carries 172 gallons versus 150 gallons on the Beneteau First 50 Standard 2006 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau First 50 Standard 2006 is the offshore and bluewater choice - at 29 950 lbs displacement and 49 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 45F5 1990 at 23 149 lbs is the more nimble, accessible option - easier to single-hand and better suited to coastal and inland sailing.
