Thanks for your swift reply. I realise it will be to much work for a very uncertain result to modify my existing large weed fin.
I really want a fin with offset base cause I belive they perform better in the large sizes. Large weeders without offset simply shifts COE too far behind the board. Do you think a Tangent Dynamics 46 would be a good match to a iSonic 133 and 9,5 race sail if focus is on early planning and upwind performance? Is Sailworld the only dealer in the US who carries Tangent Dynamics?
The location I sail get moderate amount of weeds, can get heavy in later part of the summer and fall though. However, people who sail Formula in my area say they come clear with Gsport Someweed, which has a rake of 42 degrees I belive.
Thanks for your input !
