InterProtect® For prevention and repair of gelcoat blistering
Saved by uncleflo on September 4th, 2022.
The InterProtect® products were introduced in 1985 for the repair and prevention of gelcoat blisters and quickly became the product of choice for professionals and do-it yourselfers alike. In the ensuing years it has become the standard by which everything else is measured. A study undertaken in 2001 reported that boats with InterProtect System on the bottom had a higher resale value than boats that did not. InterProtect has proven itself to be a universal primer. Below the waterline it can be used for corrosion protection on all underwater metals for hulls, keels, trim tabs and running gear as well as for blister protection and as part of the Ultimate No Sand System for new fiberglass boats. Above the waterline InterProtect is used on fiberglass and all metals. The InterProtect System was designed to repair hulls which have experienced gelcoat blistering. However, the best time to attack hull blistering is before it happens. Taking preventative action before a problem occurs greatly reduces the likelihood of an expensive repair and has been shown to increase resale value of your boat. If you’re buying a new boat, protect your investment with the InterProtect System before it ever goes into the water.

PYI Inc. | PSS Type A Shaft Seal
Saved by uncleflo on February 6th, 2022.
Product Specifications: PSS Type A Seal Dimensions The Type A PSS Shaft Seal is a mechanical face seal. The sealing surface is created between the flat surfaces of the rotating stainless-steel rotor and the stationary carbon flange. The stationary carbon flange is attached to the front side of the bellows with hose clamps, and the back end of the bellows fits over the Stern tube and is secured with hose clamps. The stainless-steel rotor is fitted on the shaft in front of the carbon flange. The stainless-steel rotor compresses the bellows before the rotor is secured to the shaft with set screws. This compression (pre-load) maintains constant contact between the two flat faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable fore and aft movement due to propeller thrust. In addition, the carbon flange is over-bored to the shaft diameter allowing it to “float” around the shaft and thus compensate for most misalignment and vibration problems. The stainless-steel rotor is sealed to the shaft by two O-rings recessed into the collar's bore. These O-rings rotate with the shaft and stainless-steel rotor and do not experience wear during operation.

Marine Lightning Protection Inc.

Given the wide range of potential issues with lightning protection of ships, it is not surprising that a common problem is that the agent does not understand how to define the most pressing concern. Ill defined Class regulations, use of ambiguous terms such as "lightning arrestor", and the widespread availability of devices with checkered histories do not help. To this end we offer a standard 20-hour consulting package that provides basic concepts, identifies prioritized issues, and develops the framework for an effective lightning protective process. Please email us with questions or details. Another fundamental problem revealed in this scientific work was that a one square foot ground plate is "hopelessly inadequate" to prevent sideflashes in fresh water.This was not addressed in these earlier standard rewrites since, at the time, there was no obvious solution. We can now solve this problem with our patented SiedarcTM electrodes that, when distributed around the hull, provide the multiple exit points needed for effective grounding.

Displacement-Length Ratio of a Yacht: Skipper's Basics – no-frills-sailing.com
Saved by uncleflo on February 24th, 2019.
When sailors are talking about their boats they often refer to ratios and numbers. That´s a tendency in human behaviour to try to generalize things to make them comparable. Of course, everybody knows that you cannot really describe apple to pears and so it´s worthless to describe a let´s say Seventies IOR-era King´s Cruiser 33 like mine to a modern day cruising yacht but we nevertheless tend to do so. The Displacement-Length-Ratio in general is a non-dimensional number. It sets into relation the displacement of a boat (expressed in pounds) to the length of her waterline (in feet). So, in general, this ratio is looking for the relation between the (heavy?) volume of water being pushed aside by a boat´s hull and the length (and therefore speed potential see for my article Hull speed vs. Froude number here) of her hull. Sounds fair enough?
