HORSEPOWER vs. SPEED (from 1977 Factory brochure) 20 HP = 20 MPH 35-40 HP = 28 MPH 50-55 HP = 34 MPH (exactly my observation--JWH) 65-70 HP = 42 MPH Also see Clark Robert's comments on performance of the 15.
The 15-foot hull was introduced in 1976 after the re-design of the original Whaler hull forms (the 13-foot in c.1971 and the 16/17-foot in c.1975), and thus all vintages of the 15 display the "smirk" appearance at the bow. The runners of the outer sponsons, which are a little narrower (in comparison) than in the 13-hull, are brought up and across the bow, forming a large reverse chine which contributes to deflecting water away from the boat at the bow. The center section of the hull is much larger forward than the sponsons and provides a fine, deep-vee entry, producing an nice ride in chop and waves. At the stern, the 15 hull has a somewhat unique transom, lowered to create depth, offset slightly to the rear to add length, and raked a few degrees from vertical. The contour of the bottom is a central rounded vee, several inches deeper than the sponsons that flank it on either side. There is not a large flat bottom area aft, which makes the hull a little harder to plane. (Again, see Clark Robert's comments.) Because of the narrower runners and the larger rounded vee center section, the 15-foot hull is somewhat more sensitive to lateral trim than either the 13-foot or 16/17-foot hulls.
All models have a trapezoidal bow locker with drain and a stern motor well with scuppers. All models also had a rear bilge sump with drain. The hulls prior to Hull No. 5A0857 have wood embedded beneath the cockpit floor only in a one foot wide strip running up the center; later hulls had wood reinforcement for the full width of the non-skid portion. A diagram showing the embedded wood denotes all the variations. The center console had a tunnel molded in the cockpit floor from the drain sump to the console.
The lack of a flat transom made mounting auxillary or "pony" motors quite difficult, so Whaler developed a special offset bracket. This drawing shows the details of the bracket and should enable its duplication; thanks to Fred Voltaggio for sending it.
The 15-foot hull had a long run, from 1976 to 1994, and bare hulls may still be available from Boston Whaler Commerical Products Division, although the cost may be somewhat higher than when offered in the recreational line.
This head-on view shows the larger center hull section with more deep-vee entry which produces an outstanding ride in waves and chop.
Whaler and Whale
The Whaler 15 carries its weigh better than I do. Notice how the hull sits right on its lines. I often see boats, even Whalers, where the weight of the outboard has the static trim way down in the stern. Those boats sit with a very pronounced bow-up trim. Not the Whaler 15 hull. This boat has a great profile.
Whaler 15 Transom
The 15-hull can be identified by this unique transom, which is lowered from the main hull, offset several inches to the rear, and raked.
Whaler on Plane
Burt Lake, Michigan provides a nice backdrop for the Whaler up on plane and going about 25 MPH. (Bimini maker says that is the maximum speed for the bimini.) With 50 HP, top speed is about 35 MPH, bimini down, one person, calm water, small fuel load.
Three components: "desert tan" colored molding capping the hull-deck joint; a white molding with a track; a black rub rail insert into the track. The black rail runs completely around the hull in one piece, secured on the opposite side as seen here with a screw.
While the hull stayed intact, the interior of the 15-foot varied quite a bit over the years of production. Many models with various seat and console combinations were offered. The 15-foot Whaler in several models is featured in the CETACEA collection on Cetacea Page 50.
Whaler owners are generally pleased with their boats, and the Whaler-15 is no exception. Here are some owner experiences and testimonials:
