Stellar 52

Classic cruiserr

Here's the challenge: A client comes to me and wants an existing design updated. The hull in this case is a classic Sparkman & Stephens design. The interior revisions are a snap. The deck redesign was also no problem once the interior redesign had begun.

I used a true raised-saloon-type deck configuration. Modifying the hull shape coming from an existing mold, however, presented some major construction problems. As it was, the boat was a good-sailing, stiff and forgiving cruising boat. From a practical perspective, the boat could have used additional deck space and accommodation volume aft. From a theoretical perspective, the hull shape was good forward but anemic in volume and beam aft compared to the style of today's yachts.

The solution for this outdated stern came from the Taiwanese builder: "Why don't we just expand the mold aft to widen the stern?" I put the original form hull into my computer, then pushed the buttons to add a wedge down the center of the boat to result in an additional 24 inches of beam at the transom. Keel and skeg fairings were good so they remained unchanged.

With the wedge inserted, I compared the hydrostatic data for each hull and determined that we would be far better off with the modified or wedged broader hull form. Our beam increased aft. The longitudinal center of buoyancy moved aft as did the longitudinal center of flotation, giving the shape a far more modern distribution of volume.

Is this now a better boat? My experience would indicate that it's better. My computer thinks it's better. We have increased stability through additional beam. We have added just a bit to the boat's off-the-wind speed and manners by adding volume and sailing length aft. Upwind, our gains in stability and sailing length outweigh the drag of additional maximum beam. The one area that defies computer quantification is the area of feel. As is, the boat has a lovely feel to the helm. I hope my highly modified hull form shows the same balance and forgiving personality.

The Stellar 52 is a comfortable cruiser built with semicustom interiors. We have drawn a number of interior layouts, but I chose to publish this one because it was the only one drawn to graphic standards needed for publication. The other drawings are working drawings and they are a little busy with detail for clear, reduced reproduction.

The layout shows accommodations for two couples. There is a small additional cabin forward for two children. In other layouts, we have converted this cabin to an office with a fold-down berth. We have drawn just about every conceivable saloon. We have versions with inside steering and big nav areas. We have a layout with reading chairs to port flanking a TV locker. This layout shows two alternatives for the saloon.

The galley stretches across this boat. The port-side refrigerator-freezer unit can also be designed to include a washer and dryer combo unit. The forward cabin can be designed with V-berths or with a centerline double as shown. The builderÕs joinerwork is impeccable and of true furniture quality.

Constructed in ultraconservative, solid, single-skin GRP, hat-section longitudinals reinforce the generous topsides laminate. It's an icebreaker and very durable.

I appreciated having a hand in the redesign of this good boat. Stellar Yachts, 440 4th Ave. S., Kirkland, WA 98033. (888) 828-4753. Reincarnated classic cruiser with semicustom touches.
