Thanks all 3 of you for your input.
@billboard: you are right, between speed and comfort/versatility, I choose comfort.
@JasonProsser: Thank you for your input on Alpha. I will have a look at Escape too.
@HumanCartoon: Γεια σου! You confused me a bit. You suggest that the 14' is better due to my ratio of weight and height ? or due to the specificities of Mediterranean sea ?
Can you comment on wood vs. AST please as well ?
