OK foil fans…… I am not having a shot at you and commend what Darryl and the Stealth boys are doing……. However I have some questions and am asking for answers.

You do not have to address my questions and can side step as much as you like, but if you do, you will not convince me of the benefits.

Wouter’s comment about foils possibly having a greater effect on a smaller boat was very interesting and was constructive feedback.

Below are my queries and it would be appreciated if someone knowledgeable could comment on them.

1) I believe these rudders will catch weed and other debris and be difficult / slow to remove compared to non foil, kick up rudders. Do you agree or disagree. If you agree, then have you thought about how to rectify this. If you don’t agree….. Then why.

2) I am not doubting that the foils reduce pitching or allows you to load up the boat more...... I am questioning at what cost (drag). Whilst there would be minimal (still some) drag when perfectly trimmed, what about the drag when the foil loads up at the top or bottom. The reduced pitching and ability to load up the boat more may feel like you are going quicker…… But are you.

3) How much drag is produced from them in large chop when pitching is inevitable?

4) What testing has been done. Tank testing???? Have you done extensive side by side 2 boat testing with boats identical in set up and crew weight. Taking results from racing is far from an accurate way to gather data.

5) How experienced are those doing the research in controlled environments and gathering data.
