The Olympic 590 Speedster can count more than a decade of presence in the Greek Seas, and still stands out even today for its stern and transom design, the clever solutions it offers for nautical camping as well as its excellent riding.
It takes only a simple glance at its hull to find out that it's a rib for tough weather, but what really stands out for is that at the same time it is able to achieve enviable speeds even with relatively small horsepower.
With a sharp bow entry of 60° and deadrise that measures 25° at the stern, the Speedster is geared to offer soft cruises with excellent damping, enabling us to maintain particularly high cruising speeds, even in difficult weather conditions.
Its hull is characterized by the presence of a chine with negative inclination and four strakes per each side, the two lowest of which stop their course at the height of the pilot station.
One of the main features of the Olympic 590 Speedster’s deck is the unified polyester bow that provides comfortable access to the boat through the wide platform, while creating a large sunbathing and sleeping area with the appropriate addition.
A large three-seater sofa is formed in the stern, where the passengers receive the great safety offered by the raised polyester rudders right and left, which together with the double helmseat can accommodate with great comfort five people during even long distant trips.
The overall design of the deck is suitable for all those who want to travel comfortably with their family, while having the ability to spend the nights on board.
On the day of our test it was blowing at 15 knots with gusts to 20 and so we had the opportunity to find out from first hand the possibilities of the Olympic 590 Speedster.
The 8-inch power lift hanging on its transom housed a Mercury’s four-stroke 150 hp engine equipped with a Bravo I FS propeller 15 ¼" x 21".
Our calculations fulfilled our expectations and so we managed to achieve a very remarkable set-up, which showed an excellent behaviour throughout the whole engine speed range.Before started recording our measurements, we run in the open sea against the wind so as to evaluate the Speedster's cruise.
Turning our bow against the waves and maintaining high relative speed we validated the very good behaviour of its hull and its extremely robust construction, since at any point of our test we did not hear any creaking even when we were pushing it to its limits. The rib looked very well balanced and was penetrating the waves with its keel without the need for special handling by the driver.
The deep V of its hull made it easy to soften our ride, while the negative inclination of the spray rails kept the spray away from the deck. Putting the waves on our stern, Speedster's hull continued to show us a very good run, keeping the bow high when we were approaching the waves’ backside, allowing it to climb up easily over their crests.
Our ride at this sea condition was enjoyable, giving us a strong sense of safety and seaworthiness. After a long time, we approached the nearest downhill bay in order to record the performance of the 6 meter Olympic with this set-up.
With a planing speed of 6 seconds, the rib hit 30 knots in 11 seconds while its accelerations were very satisfactory.
The Speedster stood on plane at 2900 rpm, which is expected due to the design of the propeller we chose, with a speed of about 12.4 knots. Trimming out the engine to indication 1 and raising the power lift by two settings, we were travelling with 31.5 knots at 4000 rpm, burning 0.9 litters per nautical mile. The very low slip values of the particular propeller at 4000 rpm were a very good indication of the proper engine’s mounting height we chose.
The hull run clearly out of the water, leaning steadily on its aft portion without any traces of chine walking, while the rib had a very good ride attitude in each condition.
Pushing the throttle at WOT and bringing the trim excessively out to indication 2.1, the engine reached 5500 rpm and our final speed was 43.2 knots.
The above figures are more than satisfactory if we take under consideration that despite the fact that the Speedster is built on a deep V hull, it can ride quickly and economically at the same time.
Detailed measurements can be found in the PDF below.
As far as the particular engine-rib combination is concerned, we would undoubtedly suggest the Bravo I FS as a prop of our choice, but shorter by two inches. If we could place the 19" Bravo I FS instead of the 21" one that we had in our test, we will allow the engine to reach 5800 rpm, it’s maximum rpm limit, we will further improve the acceleration and the throttle response, while at the same time, we will able to load our rib more without undermining its behaviour in tough weather.
