Polar 55 - Alliage/Azzuro range
The Polar looks very nice with some good ideas; seems very similar in design & concept to the Alliage & Azzuro swing & lifting keel yachts - which are from the board of a well known designer. I think aluminum makes more sense if you're going the shoal draft route. I get nervous taking a glass boat anywhere too shallow where there's anything to potentially graze the gelcoat/antifoul/epoxy barrier coat !
just noticed the 45 foot concept at end of that Polar 55 brochure. Still a bit short on info re the "composite construction" of these yachts.
Re 7 year warranty - we had a 10 year hull warranty on a larger J/Boat (built in the mid 90's in the USA) - don't know if they still do that. Only caution is that these long-dated warranties are really just a marketing tool and can be very difficult to claim on - esp when the yacht is in a different country to the company giving the warranty; and also when the builder is a different legal entity to the marketing company who is party to the sales contract !
