Description

The Technopolymer Blade has been created by using the most recent plastic moulding technologies. Performance, which has always been a real obsession for Umberto.

These blades are ‘soft’ and footpockets are sold separately.

Fit C4 250 pockets

Specifications

Advanced polymer blade

The best result is achievable only by combining a top quality footpocket with a highly performing blade. The new Umberto Pelizzari are designed with blades that put together all the elements needed: high quality materials, a futuristic design, advanced manufacturing and great mechanical resistance.

Materials

The design and material of the blade are key features to obtain both softness, high elastic return and strong resistance to breaking. C4 has selected and tested many different polymers, selecting two blends, one for the Soft version and one for the Medium stiffness blades. These two solutions guarantee extremely high performance and resistance.

Integrated water rails

A key element feature by the C4 Umberto Pelizzari fins is the fact that the water rails are over-moulded on the blades. The length (30.2* cm), the variable height (max 17.8* mm), the thickness (3.3* mm) and the material (thermo rubber) are another important feature of these blades. The result is a blade that works perfectly with no interference from the water rails and minimal lateral sliding of the fin.

Design

The blade features a central smooth and glossy band which widens from the foot-pocket to the tip of the blade. On the sides, the surface feature a carbon fiber finish look. On the back side of the blade, the finish of the surface is exactly the opposite.

The tip of the blade is shaped as whale’s tail. The blade is 59 cm long at the center and 62.5 cm laterally. The measure takes into consideration the length from the tip of the foot-pocket to the end of the blade. The total maximum length of the blade is 79.5 cm, while the total maximum length of the fin, so including the foot-pocket, it is 91 cm.

Two long ribs are featured laterally on both surfaces of the blade, but they are 5 cm longer on the top side. On the back side of the blade there is an additional central nerve which runs almost all along the length of the blade. On the back surface, just before and after the tip of the foot-pocket, there are two 16 cm long ribs, 15 mm wide and 9 mm long, with an almost triangular section. The thickness in front of the foot-pocket is 3.4 mm, and goes down to 1.6 mm at the tip of the blade.

The angle of the blade is 29°, which added to the 3° angle of the C4 250 foot-pocket, brings the total angle to 32°.

Low weight

Today the C4 Umberto Pelizzari fins are by far the lightest on the market of long polymer blade fins. They weigh less than 1200 grams a pair.

Fantastic diving in Auckland on the weekend. Good Fantastic diving in Auckland on the weekend. Good visibility and lots of fish on offer. Large numbers of snapper and schools of kingfish prevalent where ever we found current. And only a short boat ride offshore. We are very lucky to have such a healthy fishery in the Hauraki Gulf with easy accessibility for people to catch a feed! #spearfishingnz #haurakigulf #wettie @danrogers_spearo @jdwaugh
Perfect Spring day out on the water in the weekend Perfect Spring day out on the water in the weekend. Good conditions above and below the water. Lots of fish around. @danrogers_spearo picked up a nice Kingi out of a big school and there were Snapper galore. As well as healthy numbers of crayfish. We came across all three species we have in NZ in the same spot. Spiny Red Crayfish, Packhorse Crayfish, Spanish lobster (slipper lobster). #lobster #spearfishingnz #wettie

Good to get time in the water last weekend. We hea Good to get time in the water last weekend. We headed out to Kawau and were greeted with great diving. Although water is still 14-15 degrees there were lots of bait fish, kingfish, snapper, along with John Dory and an unusual capture for us when diving the reef. A Spotted Stargazer! Visibility was good at around 6 metres. #wettie #spearfishingnz

Fins Sizing Guide

Spearfishing Fin sizes
Sizing recommendation according to 3mm booties being worn. If you are wearing a thinner sock or bare feet, go down a size. For thicker booties go up a size.
Closed foot pocket fins are designed to fit like a 'gumboot' with a bit of room to allow for your foot to swell while swimming. If you are in between sizes, we suggest going up a size. Feel free to call us for advice we are happy to help you choose the right fit.
