In smaller boats such as dinghies it is used to control the angle of the sail to the wind on each point of sail. The block is typically attached to the boom by means of a bail, which is a U-shaped piece of metal, flattened at the ends to allow attachment with screws or rivets.

Because of the improved sail control it is rare to find a non- headsail without a boom, but lateen sails, for instance, are loose-footed. The boom also serves as an attachment point for more sophisticated control lines.

The primary action of the boom is to keep the foot flatter when the sail angle is away from the centerline of the boat. Some delays for other orders are also possible, Complete Rigs for example will take around 48 days to ship.In sailing, a boom is a spar (pole), along the foot of a fore and aft rigged sail, that greatly improves control of the angle and shape of the sail. All sails such as IOM & Victoria sails and IOM rigs (and Custom sails, DF65 by Sailboat RC) will take around extra 35 days to be shipped and K2 IOM sailboats will probably be shipped around 60 days later than promised on the website items page, that is our best estimate, but please take into consideration it is just an estimate, maybe little sooner, maybe little later.
CLEW OF A SAIL UPDATE
): Due to our shop being moved to bigger and more advanced production facilities as we are upgrading our factory and also because many materials are late until they reach us, please notice that all orders will be shipped later than stated on the website items page because we can’t update all items one by one. **WE RESERVE THE RIGHT TO UPDATE THE SHIPPING COST FOR SOME ISLANDS OR EXOTIC/REMOTE LOCATIONS AFTER THE ORDER IS MADE, IN THAT CASE, WE WILL CONTACT YOU DIRECTLY VIA EMAIL.** This was a special after-COVID-19 measure or Customs rule from the countries listed and their postal offices are not allowing shipping with postal service, it is not Sailboat RC rule, thank you for understanding that. Orders for Russia and Belarus are completely blocked in international shipping traffic. Here is an UPDATED list of countries that can’t use the HR Post shipping method: Australia (smaller orders of only up to 2kg are ALLOWED for AUS with HR Post shipping!), Bangladesh, Barbados, Chile, Colombia, Iceland, Indonesia, New Zealand (smaller orders of only up to 2kg are ALLOWED for NZ with HR Post!), Paraguay, Peru, Philippines, Puerto Rico, Singapore, South Africa, Uruguay. The following countries have restricted shipping for Post shipping ( HR Post method only, our Shipping/courier delivery is not affected by this restriction!).

DF MONOCLASS WAS MOSTLY NOT AFFECTED BY THESE DELAYS AS IT RARELY REQUIRES COMPLEX ASSEMBLY AND IT IS MUCH SIMPLER AND LESS TECHNOLOGICALLY ADVANCED COMPARED TO IOM CLASS. OUR AIM IS ALWAYS TO BE BETTER AND FASTER THAN EVER FOR ALL OF YOU RC SAILORS WORLDWIDE (THAT MEANS R&D WITH NEW UPGRADES, YAY, WOHOOO!). OUR SAILBOAT RC COMPANY WAS COMPLETELY MOVING TO NEW & BIGGER PRODUCTION FACILITIES (NEW LOCATION!) AND WE WERE UPGRADING MANY PRODUCTION PROCESSES AS WELL TOGETHER WITH OUR WHOLE ORGANIZATION. *** WE HAD DELAYS (BUU!) WITH ALL ORDERS MADE FROM THE START OF APRIL 2022 UNTIL THE END OF 2022, PLEASE UNDERSTAND THIS.
