Product Overview

Why Surf Fin technologies on a wave windsurf board?

Asymmetrical foil surf type fin technology with the appropriate toe in & cant angles, enchanges the total behavior and performance of any multifin windsurf board with extra speed, control and confidence on the critical zone of the wave.

In details:

  • Tighter archs / higher rail to rail acceleration & performance through the turns

  • Higher speed with better control during the turn

  • Optimal lift to drag ratio

  • More Rail bite

 

Extensive range of fins options to choose:

  • Fin material technologies with difference flex and response

  • Layout design for different control, speed or balance through the turn

  • Asymmetrical foils designs 80/20, Flat, IFT for different carving performance

  • Full customize the turnability of your board

  • Less total weight (fins & adaptor saves up to 30-150 gr)

 

Design & Material

An innovative heavy duty high quality and super light custom composite material ensures great stiffness and fitment. Designed , engineered & tested in Crete Greece by Surfilsland passionate team (Pat pending) in cooperation With Olympic Gold and Silver Medalist, 3 × World Champion Nikos Kaklamanakis.

 

Toe in Calculation

Calculate your Side fin conventional board Toe in Angle (of your fin boxes) and choose between 2o – 3.0 degrees adaptor for a 2.5-3.5 total amount of the toe in fin angle in the board

For 80/20 asymmetric fin foil an average of toe in of 2 - 2.5 is optimum

For Flat/IFT asymmetric fin foil an average of toe in of 2 - 3.0 is optimum

For instance a 100mm Slot Box fin length measure the total difference in distance from top and bottom of the box. For example, if difference is 3mm then your board has 1.0 toe in angle which means an adaptor with 2.0 toe in angle is optimum for a total 3.0

Fin setup Options

 

Quad setup Options

Asymmetrical side surf fins with regular windsurfing back fins can be used to get the performance of the toe in, foiled setup of front fins which give a really high rail to rail performance and control through the turns without loosing the acceleration of the board in straight line. Very good setup for overall wave or jumping conditions

 

Suggestions for an 75-80kgr average rider:

Side surf fins with 7150mm2 surface area from rear trailer with 80/20 foil or 8000mm2 surface area from Grom side fins and

Quad windsurfing wave rear fins with 13cm depth and 9800mm2 - 10500mm2 surface area

 

For example in a quad 75-85lit wave board, replace your 8,9cm windsurfing fronts with a Grom with Flat or IFT foil or trailer fin with 80/20 foil and replace your 15cm fin with a 2cm (or two sizes) smaller in your rear quad windsurfing fins

 

Thruster setup Options

Asymmetrical side fins with regular symmetrical windsurfing rear fins. In that case by using the regular size for rear windsurfing fin and a smallest side fin you gain really good acceleration and control through the turns without losing the acceleration of the board in straight line. A really good setup for overall wave or jumping conditions.

 

Suggestions for an 75-80kgr average rider: Side fins:8500mm2 – 10000mm2 Small / Medium with Flat, IFT, 80/20 foil technology.

Center rear fins: 11000mm2 – 13000mm2 or 15cm or 16cm depth regular wave windsurfing fins.

 

For example in a quad 75-85lit wave board,

Option 1: Replace your 10cm windsurfing fronts with a Grom or Xsmal front fin (10 up to 11cm) with Flat or IFT foil and keep the same back fin.

 

Option 2:Replace your 10cm windsurfing fronts with a Medium front fin (11.5 cm) with Flat or IFT foil and drop down 2cm (or two sizes) in your thruster trailer windsurfing fin. If you were using 11cm fronts, drop down one size (1cm ) on your thruster trailer windsurfing fin.

 

Full quad surf fins setup options

Pure wave riding performance with maximum acceleration, control, drive and speed through the turns and very good performance on straight line. Most benefit in pure wave sailing conditions with side to side off wind. Maximum surfy feeling.

Suggestions for an 75-80kgr average rider: Side fins:9300mm2 – 98000mm2 Small - Medium with Flat, IFT, 80/20 foil technology.

Quad back fins with 9400mm2 -10000mm2 surface area Large - Medium with 50/50 symmetrical foil

Fitting instructions:

  • Insert your fin into its Fin Adapter (Left, Right and Center/Rear).

  • Secure your fin to the Fin Adapter using the provided stainless-steel set screws and the hex alen key

  • Insert the adapter and fin assembly into the corresponding type fin box (Left, Right and Center/Rear) as you normally would and secure the assembly with the fin-box set screw.

Special notes

Regarding adaptor appropriate fitment it has to be counted that tolerance is +/- 5% over the finbox dimensions, so in some cases a light sanding needed with 220grant sandpaper over a flat surface.

Handling and care

Surf fins due to their super light construction (in comparison with windsurf fin rtm technology) are much more sensitive when they get in contact with the shore or the rocks. An extra care needs to be taken to avoid damages or total distraction of the fins or the board. We don’t take responsibility for any fin loss or damage in your board.
