Brief Summary

The Rinker Captiva 186 OB for 2012 is so new you won't even find it on the builder's website. For the first time in 18 years Rinker will be offering an outboard-powered 18-footer, and by doing so is throwing down the gauntlet to usual suspects. In case you haven't guessed, this Midwest builder is getting aggressive and sees opportunity as some other builders dither. She is the smallest boat in Rinker's line but she gives no ground to any brand in class, and she also signals some big things to come.

All fuel consumption numbers are the total for all engines in the boat. Speeds are measured with Stalker ProSports radar gun or GPS. Fuel consumption (gallons per hour) measured with Floscan digital fuel-flow meter or by on-board factory-installed diagnostic instruments. Range is based on 90% of published fuel capacity. Sound levels determined using Radio Shack digital decibel meter on A scale. 68 dBA is the level of normal conversation. Time to plane is measured from start of acceleration to formation of rooster tail behind boat.

Captain's Report

By Capt. Dan Armitage

Rinker 186 OB captain Dan Armitage throws the new 186 Captiva hard over in an attempt to entice her to behave badly -- he was not successful. We tested her with a 90-hp Evinrude E-TEC.

Rinker returns to outboard power with the new Captiva 186 OB bowrider for 2012 -- its first outboard-powered boat model in 18 years! The Captiva 186 OB is a direct response to boaters who requested a sportboat package (boat, motor and trailer), a low- price point, and performance -- powered by an outboard motor. The Captiva 186 OB is also the only model in the 45-year-old boat manufacturer’s lineup that comes complete with a trailer. Rinker has identified what it considers a trend to outboard boats at the small end of their sportboat line, and I concur.

Rinker 186 OB
Outboard power options for the new Captiva 186 OB range from 90 to 150 horsepower.

The New Stern of the 186

Rinker maintained the planing hull of the original 186 BR stern-drive model and adapted the transom of the new Captiva to accommodate outboard engines. The Windline three-step retractable swim ladder is 37 inches in length and folds to secure around a skid-free step panel that doubles has a hand hold when boarding. A portable tow pylon mounted forward of the splash-well is a welcome standard item.

Rinker 186 OB
The outboard model 186 sacrifices the sun pad over the engine compartment, but offers more cockpit space than the sterndrive model Captiva bowrider.

Cockpit Details

Exercising the outboard option opens up the cockpit area on the 186, adding more than ten inches in cockpit sole length, which is surrounded by fully wrapped and upholstered gunwales that average 29 inches high. That is higher than some other sportboats in its class and it makes the cockpit just that much more secure, particularly for kids.

The layout of the Rinker Captiva 186 OB.

I liked the self-draining, open storage areas along the base of each bulwark. The sole locker underfoot that extends eight feet to the boat’s bow is obviously long enough for both water skis and fishing rods.

Rinker 186 OB
Both the passenger and helm seats feature flip-up bolsters.

The Helm

I found the helm position aboard the 186 a bit tight for my six-foot frame, with leg room a little cramped especially to starboard. At 14 inches off the floor, the helm seat height felt somewhat low for me – especially in relation the location of the throttle control which was intended to be as handy as possible when sitting in the seat and on the bolster. Shorter operators may not feel so cramped when sitting but they may lose the horizon while getting onto plane. The solution for them is to sit on the bolster -- that's what it's for. It's optional ($107) and I would recommend getting it no matter how tall or short you are.Getting the helm seat right is important on any boat you buy and the dealer is the person who can easily make it right for you by raising or lowering the seat or even moving the pedestal base slightly. Remember, this is a 18' boat and it already has a cockpit depth which is deeper than some in class. The instruments were simple and provide all of the information you need. I like the fact that the button for the horn is in red and is placed to the right of the wheel, just where it should be. On the Captiva 186 BR there is a drink holder molded into the dash just to the right of the wheel, something that the sterndrive version does not have. I would get the optional tilt steering ($243).

Rinker 186 OB
The bow seating area aboard the 186 is large enough for 2-3 people.

The Bow

A 17-inch-wide companionway leads to the Captiva’s bow area, accessed through a center windshield panel that pivots on a C-channel that extends the full-length of the seam connecting it to the passenger screen section. The forward lounge seats offer angled backs and hand-holds conveniently positioned. We’d like to see a cleat both port and starboard near the bow instead of just one on the bow. This three-cleat arrangement (the other two are on the stern quarters) is not unusual for price-point boats. There is no dedicated anchor locker, but it is easy enough to stow your anchor in one of the large bins under the bow seating. The bow cleat is in exactly the right place when tying off an anchor rode. There are back rest cushions affixed to the boat in front of each console, on the sides, and forward so no matter where your guests sit in the bow they will have a comfortable back rest.

Rinker 186 OB
The 90 horse-powered 186 is nimble and has a WOT of nearly 35 mph powered by a 90-hp Evinrude E-TEC outboard.

Outboard Power

The 90-hp Evinrude E-TEC is a good match for the 186 for owners who want to keep the boat as economical as possible, and are not going to be towing waterskiiers with a boat loaded with friends or family. I reached speeds approaching 35 mph during testing, which makes it ideal for a couple blasting around the lake, or a boat for teenagers where you don't want them going too fast. Boaters who plan to tow tubes or carry more than two passengers may want to opt for a 115 or higher outboard. Hot shots, of course, will go right for the 150-hp Evinrude, which will move this 2,310 lb. (1,048 kg.) boat as fast as I would want to go. The Captiva’s hull carries a slight reverse to its chine, which offers lift at the hole shot and stability at speed. I found the boat to be a bit sensitive to load distribution at slow speeds which is not unusual for an 18' boat with a 20-degree deadrise, which is deep for this size boat. You may want to add trim tabs. Cowboys will be very glad to have the fairly deep-V hull when rocketing off waves and wakes, or when punching through a steep chop at speed.

Rinker 186 OB
The stagnation line is below the helm which keeps the boat dry at speed.

Performance and Handling

Reaching a top speed of 34.8 mph at WOT and 0 to 30 mph in 16.3 seconds, the rig is quicker than I expected. Fuel efficiency is good as well with the 90-hp Evinrude, which burned 8.2 gph at top end and less than half that at the optimal cruising speed of 17.7 mph at 3000 rpm. At that speed, I was able to execute tighter turns than I would recommend for recreational boating purposes – and do so while maintaining a single hand position on the wheel and noting no skipping or “drifting.” While testing hole shot characteristics, I found that the horizon stayed in sight despite a pedestal seat height I found to be low. I also learned that the Evinrude outboard required no trimming to get the boat neatly on plane in an average of 6.5 seconds.

Rinker 186 OB
The Captiva 186 OB is the only boat in the Rinker line that comes complete with a trailer.


Powered with the Evinrude 90-hp E-TEC, and including the matching EZ-Loader trailer, the 186 OB is the least expensive boat in the Rinker line at and MSRP of $20,876. That price makes it very competitive with the two or three other builders with 18' outboard boats on the market. Rinker says that the 186 OB is a "value" boat and I agree. I certainly recommend that you check her out before buying any boat in class.
