Aquarius Sail Owners

Posey Sailmakers (Blank White logo on Sail 812) was the original sailmaker for Bill Roberts and Boston Whaler. We continued to use Posey as our primary vendor until Dave's retirement in the late 1990's, or maybe even early 2000's. I suspect the Pattison sail was from when Erickson Yachts built the b...

The Boston Whaler sticker and the rudder castings and gudgeons on your boat indicate it was built by Boston Whaler, probably in 1982 or there about. The visible seam line on the hulls was something that was done all the way up into the early 1990's, so you are probably right that someone sanded it o...

It's quite possible that your rudders were replaced....

Photos of transom, rudder castings, hulls, mast base, etc. Anything you have might be useful.

That rudder is a 2004 vintage, fiberglass laminate. Share some pictures of the boat and I can probably give you an idea of what year the boat is as well.

I'm familiar with the Trailex version which I believe is probably based on the the one you have.

What specific questions do you have?

On Saturday, May 6th, 2023 the 69th annual MUG Race forecast was for light and variable wind conditions, but like most weather forecasts it was wholly wrong. Shortly after the start, the wind picked up leaving the river completely covered in whitecaps. The conditions were ideal for setting a course ...

The HIN may have also been attached to a metal plate that was screwed or riveted to the hull. If there are numbers molded into the hull, don't confuse the hull/mold number with the HIN. The HIN will always start with 3-letters representing the manufacturer.

The SC15 was originally marketed in two configurations - UniRig (Mainsail only) and Sloop (Mainsail & Jib). Depending on your weight and experience you might want to sail it as a UniRig if you're going out by yourself. Without the self-tacking Jib you might have difficulty trimming both sails, e...

I suspect the issue in both cases is symmetry of the rudder profile... I suspect both rudders are either asymmetrical in the same direction OR one rudder is symmetrical and the other is asymmetrical. This would result in Lee helm on one tack and weather helm on the opposite tack. This would also hol...

The rudders are identical, no difference between the port and starboard side. The original super cat rudder had three notches, up, down, and a mid position for going out through the surf. I don't recall when the change was made to remove the mid position, but I'm going to say it was probably before ...

Hello, Your experience with weather helm on one tack and lee helm on the other is not all that uncommon. You are looking at all the right things and I suspect you will find the problem with one of two things. Either one or both of your rudders are not symmetrical and the pivot point is not correct a...

The Standard 19 and the Supercat 17 both share the same mast length. The main difference between the two is that the SC19 mast had spreaders, the SC17 did not.

Congratulations on your purchase of the SuperCat 19. The parts you mentioned are unique to the SuperCat product line, however many of them are common with other model sizes. Rudders are common with the entire product line, daggerboards were common between the 20 and 19. The mast profile was common a...

Revintage, The cable was 1/4" Diameter 1x19 SS. Not sure on the diameter of the sheaves off hand, but I believe they were 2" diameter. If I am not mistaken they were a standard catalog wirerope sheave with a plain bore, ie: no bearing. Or if there was a bearing it was just a plain bushing,...

Revantage,
I would say you want to keep it to a minimum. On the old cable traveler, the slack was sufficient so that when under load the traveler car cleared the beam when near the ends. This meant that there was an inch or two of extra clearance when near the center of the beam.
