If you're not quite ready for retirement, lengthy coastal cruising and the sometimes-boxy cabin cruisers that seem to go hand in hand with this lifestyle, an Express or Sport Cruiser may be just the style you are looking for. The challenge of the Express Cruiser designer and builder is to produce a boat with style and speed without sacrificing too much on accommodations and entertainment spaces. The Cruisers 3570 and 3575 models have accomplished this balancing act better than most.
The Cruisers 3570 was introduced in 1995 and, following a redesign of the interior arrangements, the model designation was changed to 3575 in 1996. The latter remained in production through 2004.
Credit for the design goes to Cruisers' in-house design staff and the style is what is typically referred to as an Express or Sport Cruiser. The genre features a single open steering station, an open cockpit and accommodations below the foredeck forward of the cockpit.
Although these model numbers suggest a boat in the range of 35 feet in overall length, this model measures 39' 3" when the swim platform is figured in and 37' without the added platform. It's important when calculating the cost of dockage to keep in mind that most marine facilities will consider this a 39-footer rather than 35' and charge accordingly.
The 13' maximum beam is quite typical for a modern design of this length although the section shape of the hull is fuller forward than is typical. This allows for increased interior volume and greater accommodations at the cost of a bit of a pudgy look. The angle at which the bottom of the boat slopes relative to the plane of the water, or deadrise angle, ranges from about 13 degrees at the transom to slightly more than 21 degrees near the forward end of the waterline. The angle at the transom is typical for this style boat although the forward angle is slightly flatter than normal. The advantage of the reduced angle forward is two-fold in that it permits wider beam at the chine for greater interior volume and accommodations and provides greater lift and improved speed with less horsepower and fuel consumption. This is much the same as a flat rock skips across the water with more ease than a round or sharply angled one.
There are tunnel-like pockets in the after sections of the hull bottom for the propellers to reduce the shaft angle so that the propellers are more efficient. This also has the secondary effect of reducing the draft and vulnerability of the propellers to damage.
The hulls and decks of the 3575 are each constructed within one-piece molds using chopped strand fiberglass, fiberglass mat and woven fiberglass cloth. A balsa wood core is used between fiberglass laminates in both the hull and deck and a system of plywood stringers and frames, encased in fiberglass mat, is used to support the hull structure. A number of separately molded liners and interior components are installed before the deck and hull are joined, in a shoebox fashion, with stainless steel screws into a wood cleat along the deck-to-hull joint.
All deck hardware is stainless steel, attached with stainless steel fasteners and backed with aluminum reinforcing plates to further strengthen highly stressed fittings such as mooring cleats.
To help prevent osmotic blistering, Cruisers uses a vinylester resin for the first, outer layer of fiberglass although subsequent layers are set in general purpose casting resin which is significantly less expensive than vinylester resin.
The 3570/3575 features a slightly raised cabin trunk forward of the windshield with a narrow side decks outboard of the cabin. The bow pulpit is an integral part of the deck mold and has a center slot for the anchor to be raised and stored with an anchor locker aft of the pulpit. There are three round opening hatches in the cabin top and a welded stainless steel rail that surrounds the entire foredeck.
Access to the foredeck from the cockpit can be challenging if the normal side deck path approach is followed. The deck along the cockpit is only slightly more than five inches wide, offers no secure hand holds and the life rail is a mere 12" high along this path. This route should not be attempted by other than sure-footed crewmembers and shouldn't be attempted, even by them, while the boat is underway. There is a second, somewhat awkward path, through a center opening in the windshield but the easiest and safest passage to the foredeck is through the forward deck hatch.
The cockpit is very nicely designed with a raised bridge deck forward to starboard and 10' X6" lower cockpit with an L-shaped settee in the port stern. The bridge deck is particularly well laid out, offers excellent visibility from the helm and can comfortably seat four adults. There is a small wet bar aft of the helm seat and a table that can be fit at the lower cockpit settee. I find cockpit tables are not very practical while underway because they take up too much room, they are not very well supported and break easily if a crewmember happens to accidentally be thrown into one while under way. However, they do come in handy when entertaining dockside or at anchor.
There is a transom gate at the starboard stern that opens on to a 20" deep swim platform which is integral with the hull. In addition, most post 1985 models are equipped with an additional 27" deep fiberglass swim platform that spans the width of the transom. The result is a huge deck area, roughly 35 sq. ft., with a stowable swim ladder for easy boarding from the water.
As mentioned earlier, the 3570 model differed from the 3575 model of subsequent years only with the interior arrangement. The arrangement of the 3570 model, although unique, was not very practical for entertaining or accommodation guest below. This arrangement featured a port side entrance, a tiny port side galley and a large circular dinette forward where the V-berth would normally be. The head is to starboard opposite the galley and there is a large owners stateroom to starboard aft. The stateroom featured standing headroom and a walk-around queen sized berth. This arrangement provides a very nice owner's cabin at the expense of other accommodations.
The interior of the 3575 model seems to reflect a complete reversal of thinking on the part of Cruisers' designers in that it offers a wide-open interior with no bulkhead partitions separating cabin spaces except for the head. Not accounting for the space taken up by furniture and joiner work, the open area of the main saloon measures nearly 10' wide by 12' long making it one of the most spacious on a boat of this style and size.
The layout features a diagonal double berth forward followed by a head and shower to port and a hanging locker to starboard. In the main saloon there is a galley to port with two-burner, counter-top stove a microwave oven and front-loading refrigerator/freezer. Sure to be appreciated is the fact that the refrigerator/freezer is above the counter at eye level rather than its normal location below the counter and does not require crawling on hands and knees when trying to locate that bottle of mustard at the back of the bottom shelf.
Opposite the galley is an asymmetrical dinette which seats three comfortably and four in a pinch. There is a large couch across the aft bulkhead. and both the dinette and the couch convert to berths if needed.
The only drawback to this spacious wide-open interior is the lack of a true owner's cabin for privacy although, a draw curtain separates the forward berth from the main saloon and a privacy bulkhead and door was offered as an option to in lieu of the draw curtain.
The standard engine installation was either twin, seawater cooled 310 hp Mercury or 320 hp Crusader Marine engines with optional gasoline engine available up to 405 hp each. Diesel engine options were available from Caterpillar or Volvo ranging from 300 to 370 hp. Engines are installed below the cockpit deck and engines are installed with v-drive gears. In order to maximize accommodations, engine space is very tight and servicing machinery can be difficult. The drip free shaft packing glands and connection of the shafts to the drive gear are very difficult to reach but should not be overlooked for routine maintenance.
With standard engines and normal loads, expect cruising speeds of between 20 and 23 mph at 3,200 rpm and a top speed of about 30 mph at 4,200 rpm. With larger gas and diesel engines performance is likely to improve by 10 to 15 percent.
Standard equipment includes hydraulically operated trim tabs and Cruisers 3570/3575 is quick to plane and responds well to the helm at all speeds. Due to the previously mentioned shallow deadrise forward, the ride tends to be a little rough in large waves and choppy seas. Going fast in rough seas is a service I don't believe the designers of the Cruisers 3570/3575 intended and when these conditions exist it is best to slow down rather than risking damage.
Both of these Cruisers models were originally equipped with a very long list of standard features including reverse cycle heat and air conditioning, microwave oven, built-in television, engine synchronizer and battery charger. And, although an auxiliary generator was an option, I have seen very few of these models without this option so, when considering price, this equipment is expected and adds no significant value to a used models. In a less than robust economy and with seemingly plenty of product to choose from I would expect room for negotiation if owners realistically expect to sell these newer boats.
Cruisers Yachts are well engineered, very well equipped with standard features and generally considered to be a reasonable value even though the selling prices of used, as well as new, models are typically 25% or more higher than similar boats offered by low-price leaders in this market.
The quality of construction and the details of finish are comparable to other mid-priced models of similar size and while they may not compare to a Mercedes or Lexus, I think a Buick would be a fair comparison. Both the 3570 and 3575 models offer attractive modern styling as well as comfortable accommodations for four people and can make do for six. If your plans call for overnight cruising and you value privacy, look for an older 3570 model or the 3575 model with the optional forward stateroom otherwise any model should be a good choice for on water fun.
