Buzz is one of the most successful of all the Seacart30’s built (hull #4) and certainly in the last few years one of the most successful small multihulls on the UK racing circuit having won inshore and offshore events including Cowes week and MOCRA championships with the previous owner. In the hands of the current owner Buzz has won the RORC Offshore championship 2018, 2019 and the shortened 2020 series. She has taken several line honours against the whole of the RORC fleet including The Cherbourg race in 2018 and 2019. She completed the 2019 Fastnet race - 4th MOCRA multihull to finish in 2 days 19 hours setting a new sub 40ft multihull record in the process.
Buzz underwent a major refit in 2018, with new deck layout, new standing and running rigging, new electronics and electrics, custom 4 x wheel trailer and trailer storage box. The new revised deck layout was designed by Peter Hobson (Hugo Boss 7 Design team) and Hamble based rigger Scott Cavanaugh with the specific aim of making the boat easier and more efficient to sail in both inshore and offshore events. The sail wardrobe was specifically designed and made by Ullman and Doyles. The mainsail by Dale Mitchell of ‘Mortica’ - Australia’s’ leading Seacart30. The headsails by Doyle NZ, the same team that built Hugo Boss 7 sails.
Additional Details
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
