Did you know? #2 Sail Area over Displacement Ratio The principle is quite basic: the more sail area we have, the more power we get. This wind’s energy is used to move the boat’s weight. The lighter the boat is, the more responsive she will be in after tacking, in accelerations, and of course in her capacity to reach high speeds with a given wind force. So far, so good. The SA/D ratio was originally created to compare monohulls abilities, most of them “pushing” water. Pushing here means displacing water, as one can easily imagine these massive round hulls bouncing into waves to make route. However, since planning hulls came in, we must admit that this ratio is now a bit oldschool. From the moment a hull will plane, it will not be facing this natural brake offered by the water mass to be displaced. What about our modern cruising multihulls? With their thin bows and their hulls litteraly slicing waves? The answer is obvious: they... https://lnkd.in/gufWxCzP

Ever wondered why we insist on soil tests before diving into construction? ?? From navigating clay-rich terrains to uncovering hidden boulders, soil tests are our blueprint for success. They not only guide our engineers in designing sturdy foundations but also ensure transparency in costing for homeowners. Dive into our latest project's journey and see how these underground detectives safeguard your investment and dreams. ??

Introducing the single access point to reliable and up to date information for winter navigation in the Baltic Sea! Baltice.org -site gathers information and instructions from icebreaking authorities from all Baltic Sea countries. The aim of the site is to extend the knowledge of winter navigation and prevailing conditions in the area during ice season. At Baltice.org https://www.baltice.org you can find extensive information: ??Current assistance restrictions per country and port ??List of currently assisted ships and planned assistances ??Handy search function for ships and ports ??Interactive map showing traffic and ice situation in the Baltic Sea ??Ice reports and ice forecasts ??Reporting instructions for ships heading to Finnish and Swedish ports ??Ice navigation instructions ??Contact details of maritime authorities responsible for winter navigation in all Baltic Sea countries ??Links for giving feedback to national authorities ??Baltic Sea icebreaking reports from 2005 onwards ??Training videos for safe navigation in ice Please check it out and make full use of the site. All feedback, questions and improvement ideas are welcome. Big thanks to Mika Nyrhil? and the rest of the winter navigation unit at V?yl?virasto / Trafikledsverket / Finnish Transport Infrastructure Agency who worked hard to renew the site together with our good colleagues at Sj?fartsverket ???????? Baltice.org is a joint effort by Baltic Icebreaking Management, BIM, an organisation with members from all the Baltic Sea states. BIM is a result of the annual meetings of the Baltic states icebreaking authorities which have assembled for more than 25 years. #winternavigation #icebreaking #icereports #icecharts #assistancerestrictions #iceforecast #maritime #safety #cooperation

#NEARSHORE_CIRCULATION_AND_RIP_CURRENTS The nearshore circulation system occurring at the beach often includes nonuniform #longshore currents, rip currents, and cross-shore flows. #Rip currents are jets of water issuing through the breaker line that carry sand offshore. These currents can sometimes be observed occurring (somewhat) periodically down a long straight beach; they also occur under piers, alongside jetties and groins, in the center of embayment's formed by headlands, and at breaks in sandbars and offshore breakwaters. The offshore velocity in rip currents can #exceed 2 m/s, and they contribute to the death toll at beaches by carrying unwary swimmers directly offshore into deep water.

“REGENT lands major order for 27 #allelectricseagliders to advance #coastalmobility ” #VESSELS September 27, 2024, - Sara Kosmajac “UrbanLink Air Mobility, a South Florida-based air mobility company, has placed an order for 27 #allelectric #seagliders from REGENT Craft, a compatriot manufacturer of all-electric seagliders for #sustainablemaritimemobility , aiming to ‘advance’ multi-modal #electrictransportation ecosystems in coastal areas.” “Under the agreement, UrbanLink will operate REGENT’s flagship Viceroy seagliders, 12-passenger vessels that can travel up to 180 miles on a single charge.” “Seagliders are new type of #maritimevessel that operate a few meters above the surface of the water by combining the higher speeds of a light #aircraft with the low operating costs of a #vessel .” “REGENT’s all-electric seagliders are described as a type of vessels that cut down on the time and the cost of transporting both people and goods between coastal regions.” “The #hydrofoiling #winginground (#WIG) craft combines modern technology from a number of industries – including #electricpropulsion , #hydrofoils , modern vehicle controls, and fly-by-wire systems. This is said to provide wave tolerance, safe operations, and passenger comfort.”” https://lnkd.in/e9way2Wb Source- original post Read all my posts #MariusPreston
